摘　　要：【目的】为了解高原湖泊流域土地利用景观格局,为当地农业结构调整提供依据,更好解决高原湖泊污染。【方法】采用景观格局指数和分形理论分析方法对云南省三大高原湖泊流域的土地利用景观格局及稳定性进行分析。【结果】从流域土地利用景观格局分析,景观多样性和均匀程度表现为抚仙湖流域最高,洱海流域次之,滇池流域最低;景观破碎化程度表现为滇池流域最高、抚仙湖流域为中间水平,洱海流域最低。从耕地、园地、林地和草地的稳定性看,洱海流域最好,滇池流域最差或较差;从建设用地和未利用地稳定性看,抚仙湖流域最好,洱海流域和滇池流域较差;流域内稳定性最好的景观类型是水域,最差的是林地;景观整体稳定性表现为洱海流域最好,滇池和抚仙湖流域较差。【结论】通过研究,摸清了三大高原湖泊流域土地利用景观空间结构特征,为研究区域农业结构调整及农业面源污染治理提供科学依据。【Objective】The present paper was conducted to know the landscape pattern of land use in plateau lake basin,to provide scientific basis for the optimization of agricultural structure,better to solve the lake pollution.【Method】The landscape pattern and stability of land use in three major lake basin were analyzed by using landscape pattern index and fractal theory analysis method.【Result】The results indicated that from the analysis of landscape pattern of land use,the highest degree of landscape diversity and the degree of uniformity was Fuxian Lake Basin,followed by Erhai Lake Basin,and the lowest was Dianchi Lake Basin,the highest degree of landscape fragmentation was Dianchi Lake Basin,the middle level was Fuxian Lake basin,and the lowest was Erhai Lake Basin.From the stability of cultivated land,garden,woodland and grassland,Erhai Lake Basin was the best,Dianchi Lake Basin is the worst or poorer.From the stability of the construction land and unused land,Fuxian Lake Basin was the best,Erhai Lake Basin and Dianchi Lake Basin was poorer;The most stable landscape type in the basin were the waters,the worst was the woodland,the overall stability of the landscape in the Erhai River Basin was the best,Dianchi Lake and Fuxian Lake basin were poorer.【Conclusion】Through the research results,we could find out the spatial structure characteristics of land use landscape in the three plateau lake basins,and provide scientific basis for agricultural structure adjustment and agricultural non-point source pollution control in the study area.
