Selecting Jinghong hydropower station as a study case, we studied the spatial-temporal change of land use and landscape pattern during 2004,2009 and 2013 based on the application of RS interpretation , ArcGIS 10.1 analysis and Fragstats3.4. The results showed that: 1) Area of tea garden, traffic land, residential land, bare land, hot shrub grass and rubber plantation was a growing trend. Area of dry land, beach, tropical seasonal rainforest, tropical montane rain forest, paddy land, water and banana was a declining trend. The residential land and dry has maximum increment and maximum decrement, which annual changes percentage and increment was 5.11% , 1182.22 hm2 and 2.37%, 838.86 hm2, respectively; 2) the landscape matrix showed a trend of fragmentation and discrete distribution, and the shape of patches became more complex. The fragmentation, aggregation, heterogeneity and diversity showed decreasing firstly and then increasing trend in the whole.
