Abstract:

Located in the Town of Yulong County,Lijiang City,Yunnan Province,Lashihai is one of the most important plateau wetlands in China. This article analyzes the threatening factors of Lashihai Basin,such as climate change,agriculture development,fireburning,cofferdams and other project. Influenced by these factors,the structure and function of Lashihai ecosystem have changed a lot. Now,a “Landscape Island” appears in Lashihai wetland,and the loss of biodiversity is obvious. The wetland ecology function declines remarkably. After analyzing the factors and their influence,the authors advise that cofferdams should be demolished as soon as possible,the wetland should be protected and exploited correctly,and some countermeasures should be taken to compensate the local people for the declination of the ecology.

Key words: Lashihai Basin, environmentthreatening factors, structure, function
