Genetic types of tectonic lakes
Summarize the English name of Tianchi. Also known as Tianchi or Dianchi Lake, also known as Kunming Lake and Kunming Pool. The Great Lakes in Yunnan Province, China. In the southwest of Kunming, together with Xishan Mountain on the west side of West Lake, it is a famous tourist resort. Formed by structural collapse. There are rivers such as Panlong River. Lake elevation 1, 886 meters, covering an area of 330 square kilometers. The average water depth is 5 meters and the deepest is 8 meters. The lake is discharged from the southwest of Haikou and named Tanglangchuan, which is the source of Pudu River, a tributary of Jinsha River. In the past, floods often occurred around this lake. As early as 1262, Songhua River Dam was built on Panlong River, and Haikou River was dug in 1268 to increase the outflow of Dianchi Lake and reduce the flood disaster around the lake. 1955, more than ten large and medium-sized reservoirs were built on the river upstream of the lake, and dozens of electric irrigation and drainage stations were built along the lake to alleviate the flood disaster and ensure farmland irrigation and urban industrial and domestic water use. Carp, crucian carp and money fish are produced in the lake.
Ecological characteristics
Dianchi Lake is a eutrophic lake, and some lakes show signs of abnormal nutrition, and the water color is dark yellow-green. The organic pollution in the inner lake is serious and harmful, and the pollution develops rapidly. Some water bodies in the outer lake have been polluted by organic matter, and toxic and harmful pollution (mainly heavy metal pollution) is not prominent. Nitrogen, phosphorus, heavy metals and arsenic are deposited at the bottom of the lake, causing serious sediment pollution. Dianchi Lake has been in the state of "aging" lake for nearly a hundred years. The annual average water temperature is 65438 06℃; In the 1980s, no survey results showed that with the changes of the ecological environment in Dianchi Lake, the destruction of the ecological environment of fish spawning and hatching sites, and the influence of overfishing and the interaction between fish populations, the fish population in Dianchi Lake has undergone tremendous changes, leaving only four indigenous species, which are on the verge of extinction. For example, golden thread fish, fresh and delicious, is now extinct, an alien species.
Morphological description Dianchi Lake is distributed in the north-south direction. The lake is slightly arched, with the arch back facing east. There is a natural sand dike in the northeast, which is 4 kilometers long and divides Dianchi Lake into two parts: the outer lake and the inner lake. It is1887.5m above sea level, with a total area of 311.338km2, of which the inner lake area is10.67km2, the outer lake area is 287. 1 km2, and the lake length is 4 1.2. The sediment in the inner lake is fat, the silt is thick, there are animal and plant residues, it is black and smelly, and the outer lake is fat, brown and has skeleton mud; The upstream rivers mainly include Panlong River, Baoxiang River, Xinhe River, Liangyun River, Mario River, Daqing River, Luolong River, Laoyu River and Wangliang River. ...
Dianchi Lake is located at the foot of Xishan Mountain in the south of Kunming. Its northern end is adjacent to Kunming Daguan Park, and its southern end is in Jinning County, 5 kilometers away from the urban area. Historically, it has always been a resort for vacation and summer vacation. Dianchi Lake was called Nanze in ancient times, also known as Kunming Lake, about 20 kilometers away from Kunming. More than 20 rivers, such as Panlongjiang River, flow into Dianchi Lake, and the lake flows out to the sea in the west, and enters Jinsha River through Pudu River. It is shaped like a crescent moon, 39 kilometers long from north to south and 13.5 kilometers wide from east to west, with an average width of about 8 kilometers. The lakeshore line is about 200 kilometers long; The lake covers an area of 300 square kilometers, ranking first in Yunnan Province. The maximum depth of the lake is 8 meters, the average depth is 5 meters, and the water storage capacity is 65.438+0.57 billion cubic meters, which is known as the "Five Hundred Miles Dianchi Lake". It is the sixth largest inland freshwater lake in China.
Dianchi Lake is a plateau limestone fault lake formed by crustal movement of the Tertiary Himalayan Mountains, with an altitude of1.886m.. There are dozens of peaks around Dianchi Lake, which are surrounded by mountains and waters, and the sky is misty, forming a beautiful natural picture.
In recent years, Dianchi Lake has been seriously polluted and listed as one of the "three lakes and three rivers" by the State Council. The pollution in Dianchi Lake has gone through a long and complicated process. Water pollution began in the late 1970s, and in the 1980s, especially in the 1990s, eutrophication became increasingly serious. The causes of water pollution in Dianchi Lake are as follows: First, Dianchi Lake is located in the lower reaches of Kunming City, which is the lowest depression in Dianchi Lake Basin; Second, domestic sewage enters Dianchi Lake; Third, industrial wastewater enters Dianchi Lake; Fourth, agricultural non-point source pollution; Fifth, the rapid development of urbanization in Dianchi Lake Basin; Sixth, Dianchi Lake is a semi-closed lake, and there is not enough clear water to replace the lake. Seventh, in the process of natural evolution, the lake surface shrinks, the lake basin becomes shallow, and it enters the aging stage, and endogenous pollutants accumulate and the pollution is serious.
Transportation: Visitors from the railway station to Dianchi Lake can take bus No.24 and No.44 and get off at Haigeng Park. Ticket price 1 yuan. There is a cable car in Yunnan Ethnic Village, which runs between Haigeng and Xishan, two-way 50 yuan and one-way 30 yuan.
Admission: free.
Haigeng Park: 8 yuan
It seems that the ticket has become more expensive, and it costs money to take a bus.
