摘　　要：文章以位于黄土丘陵沟壑区的山西方山县为例,探讨该区土地潜力,建立了黄土丘陵沟壑区土地潜力评价系统和指标体系,并筛选出评价主导因子。依据区域内的土地利用现状,将该区域分为58个地块,在地理信息系统下建立属性数据库,结合有关专家判断,根据权重法对每一地块的土地潜力等级进行了评价。结果为:方山县宜农用地面积130516.43hm2,占全县土地总面积的91.05%;其它用地面积12832.27 hm2,占全县土地总面积的8.95%。For preferably solving existing problems of land utilization and establishing reasonable land utilization planning in desertification area, taking Fangshan county of Shanxi province in the loess hilly and gully region as example, authors established the system of land potential evaluation and index, and abstracted the main factors. According to the status of land utilization, the area is divided into 58 plots, and attribute database of these plots is built through GIS. Then by using method of weighting, the potential of each plot is evaluated. The result shows that the area suits to agriculture is 130516.43 hm^2, 91.05% of total land area, the other is 12832.27 hm^2, 8.95% of total land area.
