摘　　要：借助ENVI 4.8软件,对盘锦地区1994年和2009年LANDSAT 5的TM遥感影像进行解译并分析.参照国标《土地利用现状分类》的分类体系,参考调查区域土地利用特征,将研究区域划分为8种土地利用类型.利用ArcGIS 9.3软件和Fragstats 3.3软件,通过格式转换、空间分析等处理,进行了数据统计分析和景观格局指数计算,完成对研究区域的景观格局分析,结果表明:研究区域不同景观类型发展趋势不相同,人工景观类型破碎化程度在增加,自然景观类型总体保育较好,但滩涂区域受到滨水养殖业干扰较大,面积在减少,生态总体质量在下降;旱地和林地在减少,林地的破碎化程度依然较高.By means of ENVI 4. 8, the LANDSAT 5 RS image in 1994 and 2009 of Paniin City was interpreted and analyzed. And refer to the state standard of current land use classification taxonomy and the feather of the land utilization in the investigation area, the eight land use types were divided in the investigation area. Using ArcGIS 9.3 and Fragstats 3. 3, through format conversion and spatial analysis etc, the statistical data analysis and the indices of landscape patterns calculation were done to accomplish the analysis of the landscape pattern in the investigation area. The result is that the development trend of every type in the area is different, that the artificial landscape is more and more fragmented, but the natural landscape is good as a whole. Some problems should be paid more attention, such as the decrease of the mudflat, cropland and woodland.
