【目的】采用综合指数法对库车县耕地地力进行评价。【方法】在GIS支持下,应用第二次土壤普查资料及成果,利用新疆库车县土壤图、土地利用现状图叠加划分法确定评价单元7 352个,采用模糊评价、特尔斐法、层次分析法等,选取了土壤管理、物理及剖面性状、化学性状等3个方面12个影响因子,【结果】全县73 553.52 hm2耕地可分为6级,其中一级地7 713.07 hm2、二级地20 526.13 hm2、三级地14 621.53hm2、四级地11 987.8 hm2、五级地11 302.33 hm2、六级地7 402.53 hm2,分别占库车县耕地总面积的10.49%、27.91%、19.88%、16.3%、15.37%和10.06%。【结论】建立耕地地力评价体系及其模型。 【Objective】 The index of cultivated land productivity in Kuche County was evaluated by comprehensive index method. 【Method】 With the support of GIS, the second soil census data and the results were obtained. Based on the superimposition and division method of soil map and land use status in Kuqa County of Xinjiang, 7 352 evaluation units were determined. Fuzzy evaluation, Delphi method, hierarchy Analysis method and so on, 12 influencing factors were selected from three aspects of soil management, physical and profile traits and chemical traits. 【Result】 The results showed that 73 553.52 hm2 cultivated land in the whole county can be divided into 6 grades, of which 7 713.07 hm2 The total area of ​​cultivated land in Kuche County is 10.49%, 27.91% and 19.88%, respectively, of the total area of ​​cultivated land in Kuche County, , 16.3%, 15.37% and 10.06% respectively. 【Conclusion】 The establishment of cultivated land evaluation system and its model.
