The Characteristics Analysis of Land-use in Spatial Pattern Change of Shengjin Lake Nature Reserve in Recent Years
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.
