Abstract: To promote the ecological environment in the protection zone and the sustainable development of regional social economy, the study on the spatial structure and evolution of landscape pattern in Maolan Nature Reserve in 2005 and 2010 was conducted by means of the moving window method, DEM based on Arc GIS and FRAGSTATS software with high-resolution images of Maolan and the topographic map with a scale of 1:50,000. The results show that: 1) the landscape pattern of the protection zone is of considerably  high value in 5 lumps of zones with its central region of significant heterogeneity; 2) from the experimental area to the core area, SHDI decreases by 65%, ED by 46.73%, LSI by 49.71% and PD by 40.21% while CONTAG increases by 43.95% and LPI by 107.01%.The landscape pattern is transformed from the lumped balance and fragmentation in the experimental area to the mosaic distribution with an extension of agricultural land along the road in the south, in which the overall space in the buffer zone is of high density and significant heterogeneity; 3) the artificial landscape in the study area is of concentrated distribution in the slope between 0°～5°, the natural landscape to 35°～45° to decrease on both sides, between 5°～25° of the smallest, experimental pattern evolution are benign, to prevent the spread of residential areas to steep slope region. Buffer and core pattern evolution is unreasonable, the buffer not only prevents the spread of residential areas to steep slope region, reasonable planning roads and fields should also be made. In addition, the efficiency of agricultural land use should be increased; core destroying forest phenomenon is relatively serious, and agricultural land utilization is low; and 4) the factors which result in the differentiated landscape patterns mainly include the policy guidance of the development in the reserve, special geographical form and unreasonable land use.
