摘　　要：对盘锦地区1995年和2009年LANDSAT5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,将研究区划分为8种土地利用类型。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:盘锦地区景观基质主要为湿地,两种湿地类型变化呈现相对性,人工湿地景观在增加的同时,破碎化程度也在加大;而自然湿地景观虽然面积在减少,破碎化程度进展缓慢,自然景观尚处于自身可调控范畴。而人工建设用地量和工矿用地量增长迅速,这也加深了区域景观的破碎化程度,虽影响尚表现不够突出,但应加以关注。Landsat-5 remote sensing images of Panjin City in 1995 and 2009 were interpreted and analyzed. The study area was divided into eight land use types based on the standard of Land Use Classification and the current feature of the investigation area. And the landscape patterns of the study area were analyzed by means of statistical data analysis and calculation of landscape pattern indices based on the format conversion and spatial analysis. Results showed that the wetlands, inclu- ding both artificial wetland and natural wetland, were the dominant types in Panjin region. The degree of fragmentation increased with increasing artificial wetlands, while the natural wetlands decreased, and the progress of fragmentation was slow under a self-controlled condition. The area of construction land and mining land increased rapidly, which deepened the degree of fragmentation of Panjin region.
