摘　　要：选用2001年和2005年的IKONOS遥感图象,应用GIS软件Arcview提取各景观斑块,并计算斑块面积、斑块数量、景观多样性指数、景观优势度指数、景观均匀度指数和景观破碎度数等景观生态指标,对研究区的景观格局进行分析。结果表明:研究区近几年景观格局变化较大,景观的多样性指数和均匀度指数逐渐增加,破碎度指数和优势度指数则呈现减小的趋势。各种景观类型中耕地变化最为明显,斑块面积和斑块数目大幅度减小:居住用地的斑块面积增加较大,道路用地、公共用地和防护林地的面积也有所增加,水域面积有所减小。Based on the Ikonos images of 2001 and 2005, the plot was picked-up with GIS software and a series of index was calculated, which included the plot area and number, diversity, dominance, evenness and fragmentation. The landscape pattern was analyzed and the result indicated that the landscape pattern changed greatly in recent years. The diversity and the evenness increased, and the fragmentation and the dominance decreased. In all landscape types, the plot area and number of plantation decreased, and the area of inhabitation increased greatly, and the area of road, common land and shelter belt increased a little. The area of water deceased a little.
