摘　　要：土地是一种稀缺的自然资源,一个区域各部门的生产建设都要落实到土地上,对区域土地利用现状进行全面的研究和分析,能揭示人类利用土地的广度、深度和合理程度,有助于全面分析土地利用变化的内在机理,反映生产规模、水平和特点,为土地利用结构的优化调整提供依据。基于RS与GIS技术,利用三峡库区2010年TM影像数据,获得三库区土地利用现状数据,并采用计量地理学和景观生态学的方法对三峡库区土地利用现状进行分析。结果表明:由于自然条件和社会经济条件的不同,三峡库区各区县在土地类型多样化、组合类型形式和区位指数各有差异。从库区土地利用多样化指数来看,兴山县用地类型最单一,主要以林地为主;从土地利用程度来看,渝中区土地利用程度最高;从土地利用综合指数来看,长寿区土地利用综合指数最低。文章旨在为制定保护三峡库区生态环境的相关政策提供参考和依据。Land is one of scarce natural resources, the construction in an area should be based on the land. The comprehensive analysis of the land use can show the scope, depth and rationality of it. It also be helpful to analysis the internal mechanism of land use change, and provide the basis for adjustment and optimization of the land use structure. Based on the RS and GIS, the land use status data of the Three Gorges Reservoir area were obtained by using the TM images of 2010. The land use statuses were analyzed with the methods of quantitative geography and landscape ecology in this paper. The results indicate that： due to the different of natural conditions and social and economic condition, there are difference between each counties of the Three Gorges Reservoir area in land type diversification, combination type form and locational index. From the land use diversity index, Xishan＇s land use type is the most single, and forest is mainly land use. Form land use degree, the highest degree of land use is in Yuzhong District. Form integrated land use index, Changshou District is the lowest. The results provide references for making policies to protect the ecological environment of the Three Gorges Reservoir area.
