Abstract: According to the image of Landsat TM in 1995,2000,2004,2009 and 2013,this paper uses supervised classification (parallelepiped,maximum likelihood,minimum distance,Mahalanobis distance) to interpret it, and makes use of high-resolution image evaluate different interpretation methods, then determines the best method of interpretation. Using the optimal interpretation method obtained the map of land-use and land-cover change in Shengjin Lake reserve by means of 5 times image. And on this basis,use of ArcGIS landscape pattern analysis tool,by analyzing the water area,the number of polygons,fragmentation and other factors,obtain land-use and landscape pattern changes in different periods. Land-use change combined the result of natural factors and human factors,researching the spatial pattern of land-use change analysis for the past 20 years,can provide us the basis for sustainable development of the regional land use and development of resources.

Key words: land-use change, supervised classification, Mahalanobis distance, landscape pattern analysis, fragmentation
