Dabie Mountain is located at the junction of Hubei, Henan and Anhui provinces in China.
Southeast and northwest strike.
Tongbai Mountain in the west and Zhangbaling Mountain in the east are collectively called Huaiyang Mountain.
The watershed between the Yangtze River and Huaihe River.
It is 270 kilometers long.
Tiantangzhai, the main peak, at an altitude of 1729 meters, is located in the northeast of Luotian County, Hubei Province; Baimajian (called Huoshan in ancient times), at an altitude of1774m, is located in the south of Huoshan County, Anhui Province.
The mountain is divided into many diamond-shaped fault blocks by faults. From Huangmei to Tongcheng in the southeast, the foothills are straight and the slope is steep to more than 50 degrees, which is an obvious cliff.
Many reservoirs are built on the north and south sides of the mountain, including Meishan, Foziling and An Baili River.
The original forest was lush, but it was destroyed for a long time, with low coverage, serious soil erosion and serious reservoir siltation.
The existing forests are dominated by Pinus massoniana, Cunninghamia lanceolata and Quercus.
Dabie Mountain area is the main tea-producing area in China, among which Liuan Guapian in west Anhui, Xinyang Maojian in south Henan and Hanlu in northeast Hubei are all famous varieties.
Economic trees such as chestnut, tung tree, camellia oleifera, tallow and sumac are widely distributed in hilly areas.
geographical position
The watershed between the Yangtze River and Huaihe River.
Located at the junction of Henan, Hubei and Anhui provinces.
North latitude 3010' ~ 32 30', east longitude112 40' ~117/kloc-0'.
There are Tongbai Mountain in the west, Huoshan (also known as Wanshan) and Zhangbaling in the east, northwest-southeast in the west and northeast-southwest in the east.
Generally, the altitude is 500 ~ 800 meters, the main part of the mountain is about 1500 meters, and the main peak is Tiantangzhai 1729 meters.
geology
The foundation of the mountain geological structure is the Dabie Mountain fold belt in the West Qinling of Huali in the Middle Paleozoic.
It is mainly composed of pre-Sinian strata and intrusive rocks, mainly granite and gneiss.
The eastern part of Macheng was more significantly influenced by Yanshan movement.
After folding, the mountains were once quasi-leveled.
The present mountain outline was formed by the later fault movement.
Fault movement continues, and the Huoshan earthquake of 1923 is an obvious example.
The mountainous area in Dabie Mountain accounts for about 15% of the total mountainous area, and the rest are mostly low mountains and hills.
The valley between mountains is wide and open, with floodplains and terrace plains, which is the main agricultural area.
There are many deep valleys and steep slopes in mountainous areas, and the terrain is complex, and the slope direction is changeable, and the slope is mostly 25 ~ 50.
Dabie Mountain is relatively high-lying, with developed water systems on the north and south sides, which flow into the Yangtze River and Huaihe River respectively.
The main rivers flowing into the Yangtze River are □ water, □ water, Dawu River, Qinshui and diving. The main rivers flowing into Huaihe River are □ River, Zhugan River, Yellow River, Guanhe River and Shihe River.
climate
Dabie Mountain belongs to the north subtropical warm and humid monsoon climate zone, with typical mountain climate characteristics, mild climate and abundant rainfall.
Temperature and light in the same season, rain and heat in the same season, with superior mountain climate and forest microclimate characteristics, with forest climate advantages.
Annual average temperature 12.5℃, maximum temperature 18.7℃, minimum temperature 8.8℃, extreme maximum temperature 37. 1℃, extreme minimum temperature-16.7℃, the coldest average temperature in 65438 +0.2℃, and the most in July.
Average precipitation 1832.8 mm, annual precipitation days 16 1 day, average air relative temperature 79%, annual sunshine hours 1400- 1600 hours, annual foggy days 102 days.
plant
There is a great difference in forest altitude in Dabie Mountain, and the vegetation changes obviously. The height varies from more than 400 meters to 1700 meters, forming a rich and colorful forest landscape.
The patches of plantations such as Cunninghamia lanceolata, Cryptomeria fortunei and Pinus massoniana at low altitude are rich and vast, with neat forest types and distinct layers.
Cunninghamia lanceolata and Cryptomeria fortunei in the forest have tall and straight trunks and flourish; The branches of Pinus massoniana are vigorous and lush.
Quercus variabilis, Cyclobalanopsis glauca, Liquidambar formosana and Dalbergia odorifera are full of vitality and thriving.
Separated by a small piece of water, hidden in it.
The altitude is getting higher and higher, and the landscape is different. On the steep rock between the cliffs, Huangshan solitary pine stands proudly and weathered.
On the hillside, the Huangshan pine forest stands in the wind, the trunk is bent, and the branches are flag-shaped, which is beautiful and unusual.
Different seasons have different scenery.
In spring, flowers bloom, vegetation spreads, pine green and bamboo yellow, birds and flowers are fragrant; In midsummer, the trees are thick, the shade is heavy, the cool wind blows the muscles, and the summer heat is forgotten.
From autumn to autumn, pine and bamboo are heavy, maple leaves are like fire, fruits are decorated with branches, and fragrant grass is fragrant.
In winter, the wind swings in the forest, the snow presses the golden pine, and the mountains are dignified and dew-like; The snow on the top of the mountain is hard to disappear for a long time, and it blends with flowers and green leaves, so there is a beautiful view of "paradise snow".
history
Dabie Mountain is an old revolutionary base area. During the new-democratic revolution, the Dabie Mountain area centered on Tiantangzhai was the cradle of the birth of the Fourth Army of the Chinese Red Army, and countless warm-blooded men embarked on the indomitable road of resistance.
