Brief introduction of Lugu Lake

Lugu Lake, located at the junction of Yanyuan County, Liangshan Prefecture, Sichuan Province and ninglang county, Yunnan Province, is under the jurisdiction of Sichuan and Yunnan, bordering Lugu Lake Town, Yanyuan County (formerly Zuosuo District) in the east and Yongning Township, ninglang county in the west.

The lake is slightly northwest-southeast, with an area of 50. 1 km2 and a storage capacity of 2.252 billion cubic meters. Lugu Lake is a plateau rift lake, belonging to Litang River system, a tributary of Yalong River, the main stream of the upper reaches of the Yangtze River. It is the upstream source of Xiaojin River and flows into Jinsha River via Yalong River.

Lugu Lake Basin, located in Yongning Basin, is the third largest deep-water lake in China. There is an island in the lake. There are mainly Mosuo, Yi and Pumi people living around Lugu Lake, and there are also seven ethnic groups living along the coast, such as Mongolians. With beautiful natural environment and peculiar ethnic customs, Lugu Lake is a famous tourist attraction. Lijiang Lugu Lake has Mosuo cultural tourist area, and Liangshan Prefecture has Lugu Lake tourist area.

geologic structure

Geologically, Luguhu area belongs to the junction of Hengduanshan block fault zone and Kangdian Taibei oblique zone, and its formation period is relatively new, which was formed by neotectonic movement and external force dissolution in the middle Quaternary. Lugu Lake is a plateau fault subsidence lake, which consists of a northwest-southeast fault and two east-west faults.

Lugu Lake basin belongs to Bayan Kara geosyncline, Jinsha River fold system, and Paleozoic and Mesozoic strata in the lake area are developed. In Quaternary strata, only the gravel layer near the lake is seen, and there is no typical lacustrine deposit. Triangular faces and U-shaped glacial valley types of cliffs around the lake can be seen everywhere. The lake basin system is formed by fault depression and glaciation. Due to the influence of tectonic movement, the lake basin is surrounded by mountains, and the shores are mostly peninsulas and headlands.
