摘　　要：自然及人为因素影响下,生态环境体系出现不稳定波动而产生一系列生态环境问题,在区域上就会出现密切相连的不同景观格局的变化。文章以开都河流域下游绿洲作为景观变化研究区域,利用1990、2000以及2009年遥感影像数据,结合野外考察数据,利用RS/GIS技术、景观格局分析软件(FRAGSTATS)和重心模型分析方法,分析了研究区各景观类型格局的变化趋势。结果显示,1990-2009年间,研究区耕地面积明显增加,景观多样性略有下降的态势,景观复杂性及景观异质性程度在减少。景观破碎化程度比较高,其中,其他地类及耕地的破碎化程度相对较大。各地类的中心均向东迁移。Due to the natural and human factors, unstablity of the ecological environmental system couses a se- ries of ecological and environmental problems, accordingly, there will be changes spatially in different landscape pattern that are closely linked. This paper analyzed the trend of changes landscape patterns of the downstream oasis of Kaidu river from the 1990; 2000,2009 TM/ETM＋ remote sensing image and field data using RS / GIS technique, landscape pattern analysis software （FRAGSTATS） and center of gravity model. The results showed that the area of farmland was substantial increasing trend during 1990-2009, the landscape diversity, heterogeneity and complexity of study area were increasing trend. The landscape fragmentation degree was higher, while the fragmentation degrees of the other land and farmland＇ s were higher than the fragmentation degrees of other landscapes. The center of gravi- ty of the all landscape types had a whole migration trend to the eastern area.
