[ Method ] Taking sever- al lakes in Yunnan Plateau as example, the distribution characteristics and rules of plant community in lakeshore wetland of Yunnan Plateau were discussed. The degradation and causes of lakeshore wetland were analyzed. [ Resultl The wetland plants were characterized by reduction of the aquatic plant species, the decline of the species diversity and the biomass. Fast breeding vegetation with high fat and pollution tolerance, strong adaptability was easy to form a single optimal community. Some representative and sensitive to pollution plants deteriorated or destroyed. These phenomena reflected the changes of water quality, the worse pollution, eutrophication and the acceleration of turning wetland to land. The causes of wetland degradation and biodiversity included increase of population pressure, industrial and agricultural development, advance of urbanization, unreasonable cultivation, over-exploitation and eutrophication, etc. [ Conclusion] The study provided theoretical basis for the protection, environ- ment evaluation and sustainable development of lakeshore wetland.展开更多
