现有的土地评价工作侧重于土地应用功能，而对土地生态环境功能的考虑比较少。为了探索考虑生态环境功能的土地质量评价方法，选择生态环境条件脆弱的泸定县为研究区，在土地利用类型的基础上，加入坡度、坡向、高程等地形要素指标，建立土地生态环境质量评价指标体系，并应用GIS、RS和层次分析( AHP)技术获取评价因子专题图，经过图形叠置生成泸定县土地生态环境质量等级图。评价结果显示，影响研究区土地生态环境质量的主要因素为坡度、降水量、高程、植被指数和土壤质地等。经过对泸定县土地生态环境质量评价等级与地貌类型、土地利用方式及生态环境因素进行对比分析，认为评价结果与现实条件吻合较好。

The current soil assessment met hod focuses on the application function of soil, while the ecological environment func-tion is not largely considered. In order to examine the soil quality assessment met hod in consideration of ecological environment function, an ecological environment qualit y assessment index syst em w as developed to evaluate the soil quality of Luding Coun-ty, a typical y vulnerable dist rict of ecological environment. T he system w as based on land use and incorporat ed the topographic factors such as slope, aspect , and elevation. GIS, RS, and Analytic H ierarchy Process ( AH P) t echnique were employed to obtain the thematic maps of evaluat ion indexes, w hich w ere overlaid to generate the soil ecological environment quality map of Luding County. The results indicat ed the main factors affecting t he soil ecological environment quality in the study area include the slope, precipitat ion, elevation, vegetation index, and soil texture. The soil ecological environment quality assessment results were compared w ith the topography, land use, and ecological environment factors, which suggested that the assessment results are in accordance w ith the actual conditions.
