The origin of Qiandao Lake, the origin and formation of Qiandao Lake

In 1959, due to the construction of a nearby hydropower dam, the water of the artificial lake continued to flood, flooding the ancient city of Chun'an. Rather than "disappearing" with a specific sacrifice, the city slept quietly under 100 feet of water like a coral reef in the form of a Han Dynasty ruin, slowly turning into a specimen.

Qiandao Lake (Xin'anjiang Reservoir) is located in Chun'an County, Hangzhou City, Zhejiang Province, and a small part of it connects to the northwest of Jiande County. It is an artificial lake formed by the construction of Xin'anjiang Hydropower Station to impound the lower reaches of Xin'anjiang River, which was built in 1955 and completed in 1960. The reservoir dam is 105 meters high and 462 meters long; The reservoir is about 150 kilometers long, and the widest part is more than 10 kilometers; The deepest depth is more than 100 meters.

Under normal water level, the area is about 580 square kilometers, and the water storage capacity can reach 17.8 billion cubic meters.

The water of Qiandao Lake ranks first among the major rivers and lakes in China. The national first-class water body meets the drinking water standard without any treatment, and is praised as "the world's first beautiful water".

Geological structure: Before the construction of the reservoir, the Xin'an River entered the Chun'an Basin from the direction of Tunxi in Anhui Province, and met with Dongxi Port from the east, Jinxian River and Sui'an Port from the south, to the port, and out of Tongguan Gorge. In the upper reaches of Tongguan Gorge, the Xin'an River flows zigzags between the mountains, due to the great slope of the riverbed, the river water drop is increasing step by step, between 200 kilometers from Tunxi to Tongguan Gorge, the natural drop reaches 100 meters.

The tectonic line of the reservoir area is in a north-east direction, with faults such as the Majinfu anticline axis and Yinzhubu-Kaihua passing through, and the ridgeline is consistent with the direction of the regional tectonic line. The landform of the reservoir area is mostly erosion and denudation of low hills and karst hills, and a small part is river valley plain. Most of the reservoir bottom and reservoir bed are Paleozoic tight impervious rock formations, a small part are semi-dense or cohesive impervious and slightly permeable rock formations, and there are local impervious magmatic rock intrusions, and their outcropping elevation is greater than the design backwater elevation.

The water and soil in the reservoir area are well maintained, and the average sediment content over the years is only one kilogram cubic meter, and the alluvial and siltation are not serious. Reservoir dam site Tongguan Gorge. Tongguan Gorge has a total length of 800 meters, the elevation of both banks is 300 meters above sea level, the elevation of the canyon riverbed is 20 22 meters, the lower part is steep, the slope angle is 30 ° 40 °, and the width of the canyon is about 180 meters in the dry period.

The lithology on the left bank is Tangjiawu quartz sandstone (S3T), the right bank is the quartz sandstone of the West Lake Formation (D3X), and most of the riverbed is Tangjiawu sandstone, with a compressive strength of 150x106 Newtonm2, a friction coefficient, no regolith at the bottom of the river, and no large fault rupture zone in the riverbed.

The water of Qiandao Lake is very clear, and the water here can be drunk directly, because this is the reservoir of Xin'anjiang Hydropower Station. The Qiandao Lake used to be called the Xin'an River Reservoir, and later it was renamed Qiandao Lake.

Qiandao Lake was formed as an artificial lake for the construction of the Xin'anjiang Hydropower Station to hold back the reservoir, and the origin of Qiandao Lake is rich in water, which gave Qiandao Lake a foundation for its formation.

Qiandao Lake is located in Chun'an County, Zhejiang, because of the completion of the Xin'an River Reservoir, the lower reaches of the Xin'an River were intercepted into a huge lake, and the peaks that stretch not high and are not extinct are also covered by the lake, forming islands, a total of 1078 islands, hence the name of Qiandao Lake. The most wonderful feature is that there are large islands surrounding the small islands in the Qiandao Lake, and the large lakes hide small lakes, and the turquoise water is separated by the islands, and each of them forms a small lake, which is as clear and charming as green leaves and dew.

The origin of Qiandao Lake is inseparable from the geographical location of Chun'an, and the rolling Xin'an River flows through the county, and the abundant water sources make Qiandao Lake have a foundation for formation. Chun'an County is the ancient Hangzhou and Huizhou water transport must pass through the place, since ancient times the geographical advantages, more mountains and more water and very little arable land, for the beautiful scenery of Qiandao Lake, provides the original resources.

Qiandao Lake, also known as the Lake of Thousand Islands, is located in Chun'an County, Hangzhou City, Zhejiang Province, and is an artificial lake dominated by reservoirs. Qiandao Lake got its name because of the many islands of different sizes on the surface of the lake, forming a spectacular scene. So, what is the origin of Qiandao Lake?

Let's explain it to you.

Legend has it that Qiandao Lake was originally a plain, but then there was a great flood here, and the water was so strong that it rained non-stop for a while, far more than any other heavy rain in the history of the area. Floodwaters swept in and submerged most of the plains in the area, leaving only a few hills, forming what is now known as Qiandao Lake.

After historical evolution, Qiandao Lake has gradually formed a unique topography and landscape. The islands in the lake vary in size, from small as a flower pot to as large as a mountain. These islands come in a variety of shapes, some resemble dragons, some resemble tigers, some resemble bells, and some resemble harps ......Each island has its own characteristics and stories, which have become a unique landscape in the Qiandao Lake Scenic Area.

In addition to the islands, Qiandao Lake has many other wonderful landscapes, such as the moon in the three pools, the Longjing Tea Garden, and the Xiaoyue in Nanping. Together, these landscapes constitute the unique charm of the Qiandao Lake Scenic Area, attracting many tourists to come for sightseeing.

In conclusion, Qiandao Lake is a man-made lake, but its beautiful scenery and unique landforms make people can't help but imagine the history and legends here. Whether from a natural or human point of view, Qiandao Lake is a great place to visit. <>

Summary. Qiandao Lake was originally called Xin'anjiang Reservoir, which was formed by artificial dams, and was formed to build Xin'anjiang Hydropower Station to impound the lower reaches of Xin'anjiang River. And more importantly, there are more than 1,000 large and small islands in the lake, so on December 15, 1984, the Zhejiang Provincial Geographical Names Committee officially named the Xin'anjiang Reservoir as "Qiandao Lake".

1. Ecology of Qiandao Lake.

The trend of transformation from eutrophication to eutrophication in Qiandao Lake showed that the polluting elements were heavy metals, nitrogen, phosphorus and organic matter, cages and pleasure boats. Water temperature stratification, the annual average temperature is 19 6, the surface layer (water surface to 10m underwater) temperature changes greatly in September, the average is 28 2 24 4, and more maintain a higher water temperature, called the warm water layer, which is greatly affected by floods, the middle layer (10-30m) is the constant temperature layer, the water temperature is maintained about 10 all year round, there is a water temperature mutation point above and below 30m, this layer can also be called the thermocline.

Qiandao Lake is an artificial lake formed by damming and storing water for the construction of the Xin'an River Mapin Hydropower Station in 1959. The lake area is 573 square kilometers, the lake has 1078 islands of different sizes, the average water depth is 34 meters, the visibility is 9-14 meters, it is a national first-class water body, and is praised as "the first beautiful water in the world" by Mu Qing, the former president of Xinhua News Agency.

Qiandao Lake Scenic Area, also known as Haomochong Xin'anjiang Reservoir, Qiandao Lake is shaped in the form of branches, there are 1078 large and small islands in the lake, the large and small islands in Qiandao Lake have different forms, and the distribution of archipelago is sparse and dense, and there is a list.

Located in the southwest of Chun'an County, Hangzhou City, Zhejiang Province, China, Qiandao Lake is a beautiful natural freshwater lake known as the "No. 1 Lake in Zhejiang". Today, I will introduce the origin and formation of Qiandao Lake to Da Li's hometown.

In ancient China, Qiandao Lake used to be a small village called "Xinpu". According to legend, 1,500 years ago, there was a major flood in the area that inundated the village of Sinpo and the surrounding hillsides. At that time, one of the gods who saved the village blocked the mountains and rivers on the hillside, forming a small lake.

This small lake is today's Qiandao Lake.

There is also a scientific explanation for the formation of Qiandao Lake. During the ancient Ice Age, the earth was moistened by the massive flow of water and rain formed after the melting of snow and ice. Under the action of the earth's crustal movement, these water currents brushed out a large reservoir, which is now Qiandao Lake.

Over time, Qiandao Lake has evolved into a beautiful lake with crystal clear waters and spectacular views. There are more islands in the lake, and there are as many as 1078 islands of all sizes, so it is named "Thousand Island Lake".

If you're planning a trip to Qiandao Lake, here are some recommended attractions. The first is West Lake Island, which is the largest island in Qiandao Lake, with a pleasant scenery and perfect for recreation. The second is Neverland, a theme park with lots of fun rides that are very popular with kids.

In addition, there are also attractions such as Santan Yinyue, Longchuan, Daling Lake, etc., each of which is worth visiting.

In conclusion, Qiandao Lake is a beautiful lake with a long history and spectacular landscapes. If you want to experience the beauty and magic of this place, plan a trip that is sure to leave a lasting impression on you. <>
