2. The lake is whispering in the withered grass, and the flapping sound of one or two ducklings comes from time to time in the distance, which makes the lake more lonely and deserted on a moonlit night.
Counting the white sails, on this golden sea, just like a few white feathers, floating gently and leisurely.
The sea is full of Ying Ying, shining in the sunset, the waves jumping like naughty children, and the sea is golden.
The lake is hard, like a flawless jade, shining with beautiful luster.
The lake is quiet, just like a mirror, clearly reflecting the blue sky, white clouds, red flowers and green trees. The lake is covered with a layer of mist like blue smoke. From a distance, only gray mountain shadows can be vaguely recognized.
7. The spray is a miracle of the sea, but she is more like a dancer. She can make people forget their troubles and enjoy themselves.
8. The sea water is so blue that people feel that the color of jade is too light and the color of sapphire is too dark, which is hard for the master to describe.
9. The sun shines on the undulating lake, like a layer of shiny broken silver on the water, and like a crumpled green.
10. Chaka is Mongolian, which means "salt sea". The lake area and water depth of Chaka Salt Lake are obviously affected by the incense festival. In rainy season, the lake area can reach 104 square kilometers, which is ten times that of Hangzhou West Lake, and the dry season is obviously reduced.
1 1. This lake is a saltwater lake. There is a layer of rock salt at the bottom, generally 5 meters thick, and the thickest part is 9.68 meters. More than ten kilometers of Mayana River flows into the southeast bank of the lake. Other water flowing into the salt lake is a small seasonal river.
12. This salt lake is a natural crystalline salt, large and pure, with a mellow taste. It is an ideal edible salt. Because its salt crystals contain minerals, and the salt crystals are blue-black, it is called "green salt". The initial proven reserves exceed 440 million tons.
13. Chaka salt is easy to mine. People only need to uncover the salt cover of more than ten centimeters to get natural crystalline salt from below. A few years later, the mined brine recrystallized into a salt layer. Is really inexhaustible, inexhaustible.
14. Yuncheng Salt Lake is located in Jinnan Basin, Shanxi Province, with an area of 132 square kilometers. Because the black mud in the lake contains seven kinds of macro elements and sixteen kinds of trace elements, people can row boats in the lake, and the black mud in the lake can beautify the skin, so it is also called the "Dead Sea" in China.
15. The Great Salt Lake contains countless salts. Chaerhan Great Salt Lake is very vast, and the lake is covered with a hard salt layer, which looks like the waves of the sea from a distance. Its salt can feed the people of the whole country for more than 60 thousand years.
2. An excellent composition describing Chaka Salt Lake in 600 words. My parents went to Qinghai Lake, my dream.
We will fly to Qinghai Province first, and then go to Qinghai Lake by bus. On the way, our car turned over one mountain after another and passed through one valley after another, just like walking in a maze in the mountains. When the car crossed a mountain again, our eyes lit up, ah! This is a big golden rape flower. At first glance, rape is like a golden carpet. When the wind blows, it swings with the wind and looks like golden waves. Our car sped along the highway in the rape field, and gradually, a light blue ribbon appeared on the edge of the rape field-Qinghai Lake. The car is getting closer and wider, and the charm of Qinghai Lake is fully displayed before our eyes.
I stood by the lake and looked around. Qinghai Lake is like a precious sapphire embedded in a valley. The sky looks so blue, so clear and so high. The water in Qinghai Lake is clear in You Lan. The endless sky and lake blend together, so you can't tell where water is and where sky is. I looked into the distance, the endless mountains and endless green grass, like a big hand holding this sapphire.
The lake is quiet, like a mirror, embedded in the valley, clear and transparent, reflecting the blue sky, white clouds, safflower and green trees. What a wonderful "underwater scene".
This lake is dynamic. A breeze blew, and the lake, just as flat as a mirror, immediately rippled like a fish scale. Layers of fine waves rise with the wind, chasing and playing with the jumping sunshine, but when Ying Ying Lake ripples to my feet, it slowly recedes, like a loving mother patting a baby who refuses to sleep.
Ah! Beautiful Qinghai Lake, your beauty is beyond my clumsy pen. I am proud that my motherland has such a beautiful Qinghai Lake.
3. A 600-word composition describing pupils in Chaka Salt Lake is unforgettable.
A few days ago, my mother and I came to Chaka Salt Lake in Qaidam Basin, between Qilian Mountain and Kunlun Mountain. The geographical location of Chaka Salt Lake is very important, and it is the only place to enter Xinjiang and Tibet.
When you enter Chaka Salt Lake Scenic Area, the first thing you see is a group of exquisite salt sculptures. Look, this little dinosaur is lifelike, with big eyes open, as if crawling slowly. I rode on the little dinosaur and carried it forward. You see, there is a large bottle of the Queen Mother of the West, which is inlaid with many diamonds, emitting a touch of elegance and looking magnificent and dignified under the sunshine. ...
"DuDu-"A small train with only five carriages is coming towards us. I got on the small train, which was very slow.
4. Good words and sentences about the meaning of plateau cold (1) In the morning, when the window is opened, fluffy snowflakes are secretly given to the earth. In August, the weather in Hada surrounds the earth, and the loneliness of heaven can't help but come with the earth. The desert is buried and the mountains can't be buried. That's a soldier. The unyielding backbone strides in the white world, and there is a Qinghai-Tibet highway, which is the abbreviation of the plateau soldiers who have condensed a lot of fatigue and thoughts.
Tibetan antelopes, wild donkeys, yaks and goshawks are all abandoned. In this uninhabited "forbidden area of life", this group of creatures struggled tenaciously and survived, as well as gray-yellow grass roots and more inconspicuous ferns.
The tenacity and tenacity of life are strongly displayed and interpreted here. On the Qinghai-Tibet Plateau, whether in Lhasa, Linzhi, Namco, Shigatse, Yang Ni, Lhasa River, or in the homes of Tibetan compatriots, the word "sacred" appears most frequently.
People introduced the sacred Tibetan Buddhism, presented the sacred Hada, praised the sacred snow-capped mountains, eagles and heavenly roads, and held high the sacred Yarlung Zangbo River and Yangni River. In short, when I came to the snowy plateau, I felt that everything here was sacred.
Good poems, words and sentences describing the Qinghai-Tibet Plateau. Looking at the blue sky and white clouds on the Qinghai-Tibet Plateau, why not sigh its sublimity and vastness? By the Yarlung Zangbo River and Yangni River, I scooped up a handful of river water, put it in my mouth and wiped it on my face. Why don't I sigh its purity in the coolness? These, naturally, are associated with the sacred.
The Qinghai-Tibet Plateau makes people look up, how can it be just its altitude! (3) The songs of the snowy frontier are fascinating. "Who brought a distant call, who left a permanent expectation? The sonorous singing on the Qinghai-Tibet Plateau makes people feel the long history, the vast grassland and the magnificent sky.
The soul seems to have been purified, as if it were in an endless grassland, carefree and brainless. Beauty is revealed in songs, including melody beauty, voice beauty, scene beauty, humanity beauty and emotional beauty. At this time, I have been integrated with sound, melody and scene.
Singing expresses my feelings and reveals my wishes. I am a natural thing, I am with nature, and nature is eternal at the moment of singing! (4) Dream, written in Xining, picturesque Qinghai Lake, close at hand, with endless rape blossoms, is better than the fresh air in Wan Li, covering the sky, bird droppings are like rain, and the bird island is uninhabited, attracting countless people to stop and visit the Minotaur Monument at the source of the Yellow River, gaping at Princess Wencheng, and marry a natural whip here. It seems to have crossed the illusory space of history ... where rivers are dense, Golmud is next to the cornucopia of tornadoes and mirage. There are many beautiful crystals in Chaerhan Salt Lake on the vast Gobi land. Thousands of Hu Yangshu are dancing on the water in the breeze, and cars are swaying. This is the unique landscape of Salt Bridge ... Also known as Jed Everest Glacier in the front of Cocoa, it is magnificent and beautiful. On his contradictory comments in Mongolian: Yu Xufeng, a Taoist holy place with an altitude of more than 6,500 meters, is the highest peak with an altitude of 7,723 meters on its left side, and Mu Zi Tage is a karst landform with a height of 1 10,000 square kilometers, which is not inferior to the wonders of Yunnan Stone Forest.
5. The poem Lhasa describing Tibet
Apocalypse me! This is the apocalypse.
This mysterious Lhasa
It is the sky that pushes mountains, vastness and white flags in front of me.
Let me hold my breath
Cry loudly! This vicissitudes of life face
The purity that can't be calmed by putting your hands together
And sacred.
Ah, give up, this world!
There are my sleepless eyes above the snow line.
There is my mysterious Potala Palace.
In Lhasa, I was heartbroken at E79FA5E98193E78988E69D83313331323464.
Blue covers me and white buries me. Sunshine.
Sunshine. The beloved sunshine.
In the silence of Lhasa
I fell to the ground.
The tent where I live
The accounting office where I live,
In the tall and wide Qiangtang,
She is the hinterland of the Qinghai-Tibet Plateau,
The sacred north of Tanggut,
So big, so desolate.
The accounting office where I live,
On the pasture where wild yaks live,
In June, the snow waves rolled for 8 thousand miles.
Clouds hold up mountains,
Oh, yo-ho-it's too big.
The accounting office where I live,
Surrounded by the powerful protector King Kong,
The goddess of salt lake flies in the air,
The prayer wheel is supported in the sky,
The prayer flags are tied to the sun.
The accounting office where I live,
This is a pile of things made of cow hair and horns.
Auspicious bodhisattva is enshrined in the middle,
The heating card on the stove sleeps on the mat,
There is a skylight overhead.
The accounting office where I live,
Summer in the mountains, winter by the lake,
Like a boat crossing the ocean,
Walking, stopping, falling and rising,
Dad always paddles.
The accounting office where I live,
There is a dog lying at the door, cow dung wall.
Women butter, men tend sheep,
Air-dried meat makes me strong, and milk makes me fantasize.
The accounting office where I live,
Is the highest accounting firm in the world,
There are so many girls who love me,
But I don't know why I want to wander,
One day I said goodbye to my hometown.
Hadasong
In my hometown,
There are lamas everywhere,
They dedicated their whole lives to Hada.
Needless to say, you are a fairy ribbon,
Good luck flying out of the world;
Needless to say, you are the sacred snow of Mount Everest.
Clothes falling into dreams.
Lhasa, Lhasa, you are the Hada of the world.
Needless to say, you are the fresh milk of a ewe.
It is the Yarlung Zangbo River floating in the sky;
Needless to say, you are the lover's lovesickness,
This is silent singing.
Robe, you are Hada in the sky.
Needless to say, you are a summer breeze,
Send the coolness of the ice tower goddess;
Needless to say, you are the warmth of winter.
Gorkon on the frozen soil.
Crops, crops, you are Hada of the Fruit Festival.
Needless to say, you are the integrity you earned.
Hang the fragrance of the moon around your neck;
Needless to say, you are the melting of sunshine,
Soft as a blessing.
Ma, Ma, you are Hada of Mercedes-Benz.
I have a white hada,
I want to dedicate it to Shambhala in the distance;
I have a colorful hada.
I want to dedicate it to my Tibetan mother;
I have a golden hada,
I want to dedicate it to Qiangba in Wuliangshan.
Jamba and Jamba, you are Hada of the revolution.
In my hometown,
Living with my parents,
They dedicated their whole lives to Hada.
6. The six major lakes in the saltwater lake are the largest saltwater lake and the largest lake in the world.
Dead Sea-the lowest lake in the world and the highest salinity lake. Great Salt Lake-the largest saltwater lake in America.
Aier Lake-the largest lake in Australia. Qinghai Lake-the largest lake in China.
Namco-the highest saltwater lake in the world. Geographical location is located in the abdomen of Eurasia, between Asia and Europe. The east, north and west banks of the lake belong to Turkmenistan, Kazakhstan, Russian Federation and Azerbaijan respectively, and the south bank belongs to Iran. It is the largest lake and the largest saltwater lake in the world.
Basic overview The Caspian Sea is an out-and-out inland lake, so why is it called "sea"? Judging from the natural characteristics of the Caspian Sea, the Caspian Sea has vast waters, vast smoke waves and endless winds and waves, just like the rolling waves of the sea. At the same time, the water in the Caspian Sea is salty, and many aquatic animals and plants are similar to marine life.
In addition, judging from the reasons for the formation of the Caspian Sea, there are Caspian Sea, Aral Sea, Mediterranean Sea, Black Sea and Azov Sea. Originally part of the ancient Mediterranean. After the evolution of land and sea, the ancient Mediterranean gradually narrowed, and the outline, area and depth of the above-mentioned sea areas changed many times. Therefore, today's Caspian Sea is a remnant of the ancient Mediterranean Sea, which geographers call "Sea Trace Lake".
Therefore, people call the world's largest lake "Caspian Sea". In fact, it is not a real sea.
The south and southwest of the Caspian Sea are surrounded by the Elbers Mountains and the Caucasus Mountains, and the other two sides are flat plains and lowlands. The Caspian Sea is long and narrow from north to south, slightly "S"-shaped, with a length of about 1, 200 kilometers from north to south. It is the longest and only lake in the world whose length exceeds 1000 km.
The east-west average width is about 320km, the coastline is about 7,000km, and the area is 37 1000 km2, which is almost equivalent to the area of the Baltic Sea, 10 times that of the Azov Sea, accounting for 14% of the world's total lake area (2.7 million km2), and 245% more than the total area of the famous Great Lakes in North America. The total volume of this lake is 76,000 cubic kilometers.
The Caspian Sea consists of Mangeshlak, Kazak, Turkmen, Kela-Si Nuo-Wotsk and other bays. The surface of the Caspian Sea is 28 meters below the ocean surface, and the average depth of the lake is about 180 meters.
The depth of the Caspian Sea is different, shallow in the north and deep in the south, and the bottom of the Caspian Sea inclines from north to south, which can be roughly divided into three parts: the northern part is generally 4~6 meters deep; Intermediate water depth 170~790 meters; The south is the deepest, and the maximum depth can reach1025m. There are about 50 islands in the Caspian Sea, covering an area of about 350 square kilometers.
There are more than 130 rivers, such as Volga River, ural river River, Kula River and telek River. From 1940 to 1970, the average annual inflow of fresh water is 2.864 million cubic kilometers, of which Volga River, ural river River and Terek River account for more than 90%.
The whole sea area can be divided into three parts: north, middle and south, separated by many islands and shoals. Beili coastal slope is gentle, and the water depth is very shallow, only 4~8 meters, and the deepest part is only 25 meters. The seabed is a corrugated sedimentary plain, and the water volume only accounts for 1% of the total water volume.
In the Middle Caspian Sea, there are many steep slopes on the coastline of the Great Caucasus Mountains, and the east coast is relatively steep near the Mangeshlak Plateau. The bottom is the shelf in the east and the Gerbat basin in the west, with a water depth of 790 meters; Water accounts for about one third of the Caspian Sea.
The South Caspian Sea has a low coast, a broad east-west continental shelf and a depression in the west. It is the deepest part of the Caspian Sea, with a large amount of water, accounting for about two-thirds of the entire Caspian Sea. Seabed sediments and sand containing shells in the North Caspian Sea; There is much mud and sand in the middle Caspian depression, and there are many shells, gravel sand and clay on the east and west coasts. The deep water area of the South Caspian Sea is silt and clay containing thin layers of iron sulfide, and the marginal areas on the east and west banks are sand, lime mud, shells and gravel.
The hydrological characteristic flow is mainly cyclone circulation, and some local circulation can be formed in each sea area. After entering the sea, the North Caspian Sea and Volga River are divided into two tributaries: the main river flows south along the west bank; The other branch flows eastward along the north shore, forming a small anticyclone circulation in the northeast.
The velocity changes with the wind, generally between10 ~15 cm/s. When there is strong northerly wind, the velocity in the west reaches 30~40 cm/s, and the maximum can reach100 cm/s. The central Caspian Sea is controlled by large cyclone circulation.
There is cyclone circulation in the northwest and southeast of the South Caspian Sea. Therefore, a coastal current from north to south is formed in the west of the Caspian Sea, with an average velocity of 25~35 cm/s, while a coastal current from south to north appears in the east.
The average velocity is about 10~ 15 cm/s, and the distribution of water temperature varies with seasons and regions.
In winter, there is a great difference in surface water temperature between the north and the south. In February, the temperature in the North Caspian Sea is only 0. 1 ~ 0.5℃, and the temperature in the South Caspian Sea can reach 8 ~ 10℃. The temperature difference in summer is small, generally 24 ~ 27℃.
The vertical distribution of water temperature also changes with the seasons. In winter, the water temperature in the North Caspian Sea and the Middle Caspian Sea is almost unchanged, and there is a thermocline in the South Caspian Sea at a depth of 50~ 100 meters.
In summer, the temperature difference between the upper and lower layers at the depth of 30~50 meters in the central and southern waters is large. There are 130 rivers flowing into the Caspian Sea, and the annual runoff into the sea is more than 300 cubic kilometers.
Among them, the runoff of Volga River into the sea is 256 cubic kilometers, accounting for 85% of the total runoff of Caspian Sea. The discharge into the sea has great seasonal and interannual changes, which directly affects the changes of salinity and water level.
Seawater is low in chloride and high in sulfate and carbonate. The salinity of seawater is about two-thirds lower than the standard salinity of seawater.
Generally, the south-central part is 12.0~ 13.0, and the salinity outside the Volga River Delta is only 0.2. The seasonal variation of salinity is often between 0. 17 and 0.2 1.
From February 65438 to April the following year, the North Caspian Sea often freezes. The ice thickness is generally 0.5 ~ 0.6m, with the maximum thickness of1m.. Under the strong north wind, drifting ice can drift south to the vicinity of the Apsheron Peninsula.
The remarkable change of water level in long period and ultra-long period is the most remarkable phenomenon in Caspian Sea. Studies have confirmed that the water level of the Caspian Sea in the early19th century was 22 meters lower than that before 4000~6000 years.
During 7 ~ 1 1 century, there was a low water level. During 1930~ 1957, the water level dropped again due to the construction of reservoirs on the Volga River, excessive industrial and agricultural water use and dry climate.
Since the early 1970s, the water level of the Caspian Sea has remained at around -28.5 meters. The water level varies greatly in seasons, high in spring and summer and low in winter, with an annual variation of up to 33 cm.
The winds in the Caspian Sea significantly increase or decrease the water. In the Volga River Delta, sometimes the wind reduces the water by 4-5 meters, and the wind increases the water by 2 meters. Water level in Caspian Sea, July.
7. A few days before writing a 600-word composition for primary school students in Chaka Salt Lake, my mother and I came to Chaka Salt Lake in Qaidam Basin, between Qilian Mountain and Kunlun Mountain. The geographical location of Chaka Salt Lake is very important, and it is the only place to enter Xinjiang and Tibet.
When you enter Chaka Salt Lake Scenic Area, the first thing you see is a group of exquisite salt sculptures. Look, this little dinosaur is lifelike, with big eyes open, as if crawling slowly.
I rode on the little dinosaur and carried it forward. You see, there is a big bottle of the Queen Mother of the West, which is inlaid with many diamonds, exudes a touch of elegance, and looks magnificent and dignified under the sunshine ... "DuDu-"A small train with only five carriages is coming to us.
I got on the slow train. It took us to the depths of the mysterious salt lake. In the distance are blue sky and white clouds, endless grasslands, and salt miners are digging salt. Not far away, the endless lake, crystal clear crystal salt is white and dazzling. Ah! The car, the ground and the air smell salty. When I touch my hair and rub my clothes, I really feel salty.
As soon as the train stopped, I couldn't wait to get off and get in touch with the salt lake. I am happy to walk on the white salt beach, just like walking on the vast snow in winter, so comfortable! I lay on a salt flat that can be used by the people of the whole country for 75 years, leaving photos.
If I don't say this is Chaka Salt Lake, just look at the photos, you must think this is my winter snow photo. In the salt lake, I also experienced the most primitive artificial salt mining method in the world.
I put the big "spoon" of salt mining into the salt lake, and then pulled it up hard, and a big "spoon" was fished up with heavy salt. I playfully filled a bag with salt.
The salt here is slightly blue, which is called Daqingyan. Banyan salt is an excellent edible salt with large crystallization, pure quality and mellow taste.
I walked all the way to play, "pa-"accidentally slipped into the lake, and I suddenly became a "salt chicken." I reluctantly left Chaka Salt Lake in my wet shoes and half a pair of pants, looking forward to revisiting my old place.
