What is the area of West Lake in Hangzhou?

The West Lake covers an area of about 60 square kilometers, of which the lake surface is 6.5 square kilometers. It is about 2.8 kilometers wide from east to west, 3.2 kilometers long from north to south, and it is close to 15 kilometers around the lake. The lake is separated by an isolated mountain, Bai Causeway, Su Causeway and Yang Gongdi. According to the size of the area, it is divided into five water surfaces: Waixi Lake, Xili Lake, Beili Lake, Xiaonanhu Lake and Yuehu Lake. Su Causeway and Bai Causeway pass through the lake, while Zhou Xiaoying, Hu Xinting and Ruan Gongdun stand in the center of Waixi Lake. The Leifeng Pagoda in Zhao Xi and the Baodi Pagoda in Baoshi Mountain are separated by a lake, forming one.

Extended data

1950, the geological department sampled and analyzed the geological boreholes in West Lake Island and lakeside park. It is considered that in the late Jurassic period,/kloc-0.5 billion years ago, a strong volcanic eruption occurred around the present lakeside park area, and a large number of volcanic rocks accumulated at the bottom of Baoshishan and West Lake (mostly). As a result, the crater once fell, causing low-lying water in the horseshoe-shaped core, which is the embryonic form of the West Lake.

From 65438 to 0979, geologists analyzed microfossils of rock samples taken from boreholes near the lake. According to the combination of different fossils, the formation process of the West Lake can be divided into three stages: early lagoon, middle lagoon and late lagoon. With the development of Qiantang River sandbars, the West Lake was finally completely closed, and the water surface gradually faded, forming a modern West Lake.

The mountains around the West Lake belong to the remnant veins of Tianmu Mountain. According to different lithology and mountain height, it can be divided into two types: inner ring and outer ring. Beifeng, tianmashan, Tianzhu Mountain, Wuyun Mountain, etc. They are all in the outer circle and belong to high hilly terrain. The mountain is mainly composed of Silurian, Devonian lithic sandstone and timely sandstone, with hard lithology and not easy to be weathered and eroded.

Beautiful peaks, vertical and horizontal streams and clear running water are the areas with the most springs in the West Lake. There are Feilai Peak, Nanfeng, Huangyushan, Fenghuang Mountain and Wu Shan in the inner circle, with low mountains and low hills. The mountains are all syncline mountains, mainly composed of Carboniferous and Permian limestone, which are easily eroded by water flow, forming Xia Yan, Leshui, Shiwu, Zilai and Ziyun caves. In addition to karst hills, there are also Geling Mountain and Baoshi Mountain, which span the northern edge of the West Lake and are composed of pyroclastic rocks, with an altitude of 100 meters.
