澜沧江流域上、中、下游典型案例区景观格局对比分析

Watershed landscape pattern is important of study basin's development and sustainable utilization of natural resources based on the environment.Lancang Rive Basin in Yunnan province is of many special and important characteristics.By selecting three case study areas in up\|stream,middle\|stream,down\|stream along with river basin,based on the theory of landscape ecology,the comparison and analysis are completed in three different cases in this paper.The results show that,in general,there are difference characteristics of landscape pattern in the different location along the River basin.Relatively,integrated quality of landscape of upstream and down stream is good than middle stream in Lancang River Basin.Especially in down stream area,there is a very good codition on its ecology richness and diversity index.One of the reason resulted out the difference in landscape along the river different location is its special natural condition.Another reasons dependence on condition of the local social,economy development,and the environment pressure of population.
