摘　　要：利用GIS、RS技术和景观生态学方法，选取了随土地利用分类系统变化的可预测行强的景观格局指数如面积比重、破碎度、多样性、均匀度和优势度等分析了巴江流域1992—2009年景观格局变化特征。结果表明：巴江流域主要景观类型是耕地、林地、难利用地和草地；景观格局随时间发生了较大变化。居民地、耕地、林地面积在扩大，难利用地、草地、水体呈减少趋势。在景观水平上，景观多样性、均匀度和优势度均变化较小。Based on the GIS/RS techniques and the methods of landscape ecology, this paper has chosen Bajiang basin as the study region, selected some landscape pattern indices which change with the land use variety to reflect the landscape area, such as area percentage of landscape, fragmentation index, diversity index, evenness index and dominance index. The results show that： the main landscape patterns are cultivated land, forestland, grass-land and unavailable land, and the landscape pattern changed greatly during the study period. Rural and urban areas,cultivated land, forest land area are expanding, unavailable land, grass-land, water area are showing a decrease trend. Landscape diversity, evenness and dominance are small changes.
