| 摘 要： | 根据1995、2000、2005、2009、2013年Landsat影像，利用监督分类方法（平行六面体、最大似然、最小距离、马氏距离）进行解译，利用高分一号影像对不同解译方法进行评价，确定最优解译方法。利用最优解译方法解译得到升金湖保护区5个时期的土地利用图。在此基础上利用ArcGIS景观格局分析工具，通过分析其水域面积、图斑数、破碎度等要素，得出不同时期的土地利用和景观格局变化。土地利用变化是自然因素和人为因素综合作用的结果，利用对近20年土地利用空间格局变化特征分析的研究，为区域土地利用开发和资源的可持续发展提供依据。

| 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. |
