摘　　要：【目的】采用综合指数法对博湖县耕地地力进行评价。【方法】以新疆巴音郭楞蒙古自治州(以下简称巴州)州博湖县为例,选取与剖面性状、土壤理化性质、土壤管理和立地条件相关的13个因子作为指标,在GIS技术支持下,运用层次分析法和模糊数学法对全县耕地质量进行了评价。【结果】在博湖县19 141.27hm^2耕地中,一~四等地分别占耕地面积的比例为5.37%、43.47%、31.87%、19.29%。【结论】博湖县耕地地力处于中等水平,三、四等地主要受自然因素土壤理化性质不良、肥力较低、盐渍化程度高和人为因素土壤管理水平低的影响。[ Objective] The study aims to evaluate the fertility of the cultivated land in Bohu County by using the integrated index method. [ Method] Bohu County of Bazhou, Xinjiang was taken as the study area, and geographic information system （GIS） technique and analytic hierarchy process （AHP） and fuzzy mathe- matics methods were used in this study, thirteen factors associated with sectional traits, soil physieochemieal properties, soil management and site conditions were used as indexes to evaluate the quality of cultivated land. [ Result] The results showed that among the 1,9141.27 hm2 farmlands, the fertility grade from the first to the fourth accounted for 5.37%, 43.47%, 31.87% and 19.29% of the total farmland area, respectively. [ Con- dusion ] The Bohu fertility of arable land was at the middle level, which were mainly affected by natural fac- tors, such as bad soil physical and chemical properties, low fertility and high degree of salinization, as well as anthropogenic influence, e. g. poor soil management.
