What water is Weizi Lake?

Located in the west of Hangzhou, Zhejiang Province, West Lake is the first batch of national key scenic spots in Chinese mainland and one of the top ten scenic spots in China.

It is one of the main ornamental freshwater lakes in Chinese mainland, one of the few lakes in the World Heritage List, and the only lake cultural heritage in China.

After the Northern Song Dynasty, most famous poems were named after the West Lake, and the name of Qiantang Lake was gradually unknown. Su Shi's Seeking the West Lake in Hangzhou is the first time to use the name "West Lake" in official documents.

Name source:

West Lake used to be a bay, which evolved from a lagoon to a lagoon, an ordinary lake. West Lake used to be a natural lake, but it was submerged in the development process.

The West Lake is a lake in Qiantang County, so it is called Qiantang Lake (after the Tang Dynasty, "Qiantang" was changed to "Qiantang"), and because there is a lake connected to it in the north, the water level is lower than it, so it is called Fox Xia, so the West Lake is called Shanghu accordingly.

Introduction of artificial lake:

Artificial lake (reservoir) is a water conservancy engineering building used for intercepting flood and storing water and regulating water flow. In some places, artificial lakes exist in the form of landscapes and beautiful scenery.

Artificial lake is generally a kind of lake that people dig out in a planned and purposeful way, which is produced in an unnatural environment, that is, a reservoir that is often mentioned in daily life. Reservoir is a hydraulic engineering building used for flood control and water storage and regulating water flow, which can be used for irrigation, power generation and fish farming.

For example, in the Weiming Lake of Peking University, the reservoir is a hydraulic engineering building for flood interception, water storage and water flow regulation, which can be used for irrigation, power generation and fish farming. Very large reservoirs may also have a negative impact on local ecology.

Reasons for the formation of artificial lakes:

1. At a certain section of the river, a dam was built for people's needs.

2. The dam stopped the incoming water and the flowing water was accumulated.

3. The accumulated water constitutes an artificial lake reservoir.
