There are some springs in nature, which are not famous for their large quantity and good quality, but have some special significance or special uses and are attractive.
Jinxianquan
Jinxian Spring is located in the northeast of Baotu Spring, and it is also recorded in Poems of Seventy-two Springs in Ming Dynasty and Records of Seventy-two Springs in Qing Dynasty. The spring pool is made up of stones and squares. There is a rectangular stone on the wall of Chibei, with the words "Old Jin Quan" engraved in official script, which belongs to Li Zhongyu, former chairman of contemporary Jinan Calligraphers Association. The spring water in the pool is clear, green algae float and goldfish swim.
This spring is a famous strange spring in Jinan. When the water is full, the spring water comes from both sides of the bottom of the pool, and the flow potential is equal. The surface of the spring pool sometimes forms a north-south waterline, which floats and floats, sometimes appearing and disappearing, and shines like a swimming gold thread under the sunlight, hence the name. Wu Zeng, a poet in the Song Dynasty, recorded the old golden thread spring earlier in Notes on Nengzhai, and noticed that the golden thread spring said, "There are golden threads in the north and south of the pool, hidden in the water." Ceng Gong's poem "Spring of Golden Thread" says: "Jade always floats, breathing fresh air, and the golden thread may not go to Nanquan. Clouds compete for beautiful algae, and the moon is bright. "
In the Ming and Qing dynasties, the gold thread was still clearly visible. Later, the water surface narrowed and the water potential weakened. With the stone pool, gold thread is not common.
1956 When the park was expanded, Jinxian Spring appeared in a small pool with carved stone fence about 20 meters east of the old Jinxian Spring, so it was called "Jinxian Spring". In the ninth year of Tongzhi (1870), the three-character stone carving of "Jinxian Spring" inscribed by the people was moved and embedded in the east wall of this spring. The reason why the golden thread appeared this spring is similar to that of the old golden thread spring.
Poisonous spring
Poisonous spring is located in Tengchong, Yunnan, and is called Gualou Spring. According to legend, Zhuge Liang led the army here to "cross Shanghai in May and go deep into the barren land". The soldiers were tired and thirsty all the way. They saw a spring on the side of the road, the water was clear and had no peculiar smell, so they bowed their heads and drank in groups. Unfortunately, they died, which caused a tragedy. From then on, they were called "poison springs". After a long time, people were skeptical when they saw this poisonous spring, but no one dared to try. Someone thought of a way to catch some ducks, and immediately found that the ducks scratched their feet a few times and stopped. In less than three minutes, it finally sank and drowned. Poisonous spring water is really poisonous!
Hydrogeologist came to poison spring and found that there was a volcanic eruption recently, and the location of poison spring was related to the volcanic eruption. The analysis of water samples shows that many toxic volcanic gases, such as carbon monoxide, carbon dioxide, hydrogen sulfide and cyanohydrogen acid, have extremely high sulfur content and are fatal to animals. Human contact with animals is highly toxic.
Spontaneous surface spring
When making steamed bread, everyone knows that yeast and alkali need to be added to flour to steam soft and delicious steamed bread. Now there is a natural spring that can be used to make dough without yeast and alkali, so it is called "spontaneous noodle spring".
This peculiar spring is located near Bianer Village, Hongqi Township, Ba County, Sichuan Province, and exposed at the bottom of the gully on the north side of Bianer River. Villagers within dozens of miles of Fiona Fang often come here to collect spring water and go home to make steamed bread and pancakes, which is very popular.
What is the secret of this "spontaneous surface spring"? Lin Hualing and other hydrogeological experts finally solved the mystery after field investigation. This strange spring comes from a small fault in the local Devonian strata, with a water temperature of 17℃ and an emission of 0.05 liters per second. When the spring gushes out, you can see a string of bubbles escaping. The water quality is colorless, transparent and odorless. After tasting, there is quite a feeling of drinking soda, which should belong to carbonated spring water.
Under the action of underground high temperature and high pressure, a large amount of carbon dioxide is dissolved in this spring water, so steamed bread is made from this water and flour. When steaming, carbon dioxide gas expands when heated, which is helpful for "fermentation". Residents have been collecting water here for a long time and have summed up their experience. The containers that receive water must be sealed strictly, otherwise a large amount of carbon dioxide will escape during transportation. Be sure to mix the flour as soon as possible after you get home. You can't leave it for a long time, otherwise it will be invalid.
brine spring
This is a rare spring in nature. Wuxi county, located at the junction of Sichuan and Hubei provinces, and Ningchang town on the west bank of Daning River.
Salt spring was originally named Bailu Spring. According to local legend, an ugly hunter was named after chasing a white deer this spring. Later, after people drank it, they found that the spring water was unbearable salty, so they called it salty spring, or salt spring.
The discovery and utilization of salt springs have a long history. According to historical records: "In the seventh year of Han Yongping (64 years), this spring was tasted in Wushan and flourished in iron pot (that is, Great iron pot)." What's the big iron pot full of salt water for? Generations used to cook salt. According to local county records, during the Qianlong period of the Qing Dynasty (1736- 1795), there were 336 cooking stoves in the local area, and there were 108 1 large iron pots, which were called "square stove salt smoke".
Where does salty spring come from? Just know the local geological conditions. Sichuan and its adjacent areas were a remnant sea in the Late Triassic more than 200 million years ago. The weather is relatively dry, and the evaporation is much greater than the precipitation. The salt content of residual seawater increases accordingly. After the formation of sedimentary rocks, brine is quite rich. Whenever these strata are affected by the later crustal movement and fracture occurs, brine can rise along the fracture and emerge from the surface, which becomes a salt (salty) spring. If the pressure conditions are good, so much the better. It is not surprising that villagers use brine to make salt, which is profitable. It is not surprising that "gold goes to Wan Li" to make money.
Spring can predict the weather.
This strange spring is located in the paradise of Gu Lin, Sichuan, and is called karst spring. There are Permian limestone strata around, so the karst landform is considerable. The amount of gushing spring is quite large, reaching 500 ~ 1000 liters per second, the maximum flow rate can reach 24500 liters per second, and the minimum flow rate is only 69 liters, which is very different. Strangely, the color of water is changeable, including light blue, blue, gray blue, green, crimson, orange yellow, brown yellow and muddy yellow. Whenever there is tan, it indicates that it will rain. So it is called the spring of weather forecast.
How did this wonderful natural phenomenon come into being? After long-term observation, hydrogeologists finally solved the mystery of this spring that can predict the weather.
It turns out that the process of water color changing from blue to green and then to yellow is a hydrochemical change process, that is, the change process of sulfate ions from less to more. For example, when it is light blue, its sulfate radical is 96. 104 mg per liter; When it is emerald green, the sulfate radical is per liter 145.608 mg; When brown, sulfate is 3 19.054 mg per liter. When it doesn't rain for a long time, the sulfate content in the water reaches the highest, and the water turns yellow and brown. As the saying goes, it will rain if the weather is sunny for a long time, so finding the water color of the yellow robe indicates that it will rain.
So, where does the sulfate in the water come from? It turns out that the local rock is a Permian limestone layer with a pyrite layer about 3 ~ 5 cm thick. Many undercurrents or undercurrents pass through this pyrite layer, dissolving pyrite and bringing sulfate into the water. Because the amount of sulfate will make the spring water show different colors, the change of water color plays a role in forecasting the weather.
Hand and foot boxing
On September 6th, 1982, a local radio station broadcast a news report that a shouting spring was found in Feng Wan Township, Xinning, Hunan Province. As long as people shout in unison at the mouth of the cave, come and get water! After a while, water flowed out of the hole of the cave, flowing faster and faster, making a rushing sound. Soon, the running water gradually decreased until it stopped completely. Then, shout again, flow out again, and so on.
Similar news reports also mentioned that there is also a shouting spring at the foot of a Maanshan-shaped mountain in Jiangjiatun, Sanyou Village, Baishi Township, Xing 'an, Guangxi. When people hear the sound, the thick water column at the bowl mouth will overflow from four springs, and after a few hours, the spring mouth will dry up. One more shout and the water will come back, and so on.
Is there really a sound-induced spring in nature? Several hydrogeologists went to investigate with the feeling of solving puzzles. It turns out that all springs are geysers, that is to say, the gushing of this spring is intermittent, not continuous, nor the result of shouting.
Shameful spring
Shame Spring is located in the northeast section of Longmen Mountain in Guangyuan, Sichuan. The situation is quite like a geyser, but contrary to the characteristics of shouting spring water, when you throw a stone into the water and make a vibrating sound, the spring water stops flowing, just like a shy girl. After calming down, the spring water flowed out again and the water volume increased. If it vibrates again, the spring will "retract" again.
Why is this strange phenomenon happening? After investigation by experts, it is determined that the spring water here flows out from tiny pores and is controlled by capillary phenomenon. When it vibrates, it will produce a kind of pressure, which will soon push the spring back. After a while, the capillary phenomenon in rock and soil can attract spring water again! So there is a phenomenon of "shame".
The spring of greed-the famous spring of warning
In the early Tang Dynasty, Wang Bo, known as one of the four outstanding writers in the literary world, had two words in his famous Preface to Wang Teng-ting: "Being greedy for springs makes people feel refreshed, and doing things happily." The previous sentence said that after drinking the water from the greedy spring, people will have greedy thoughts and lose their upright aspirations.
This greedy spring does have its origin. Shimen, located about15km northwest of Guangzhou. The local area is the only place where the ancient road in and out of Guangzhou passes. The water is surrounded by mountains and the scenery is beautiful. Pedestrians will stop to have a rest when they come here. This is a well-known place. There is a well on the roadside, which tastes sweet and attracts many passers-by to scoop up a bowl to quench their thirst, which makes people feel cool and refreshing, so it is famous far and near. Among the many travelers, there are many government officials who have worked in Guangzhou for generations. Everywhere they go, they also have to dismount and rest under the tree by the well, drink a glass of well water and then go on their way. However, the local people look at these officials and keep them in mind. Nine times out of ten, when officials arrive in Guangzhou or other places, they go from incorruptible to rich corrupt officials in less than a few years, and everyone hates them. In order to remind the new official to take office, the local people should keep clean and do practical things for the people, so they set up a stone tablet next to this well and wrote the word "greedy spring", which became a famous police spring.
During the Eastern Jin Dynasty, Wu Yinzhi, the new secretariat of Guangzhou, passed by and heard about the origin of "Chanquan". He was so moved that he drank three glasses in a row. Then he wrote a poem on the stone tablet:
The ancients drank this water in one gulp.
It is not easy for officials to drink together.
After he took office, he always kept in mind the advice of Shimen villagers, was honest and upright, won the reputation of being an honest official and won the support of all the people.
With the passage of time, the original stone tablet experienced thousands of years of wind and rain erosion and peeling, and by the Ming Dynasty, it had disappeared. However, the villagers warned the officials that their goodwill still existed. In the 24th year of Wanli (1596), Wu Ci-shi's Poem of Greedy Springs was re-engraved and moved to the side of Wanghai Building in Yuexiu Park, so that more officials could see it and take this opportunity to alert themselves and learn from Wu Yinzhi.
