为了解清原县的耕地地力现况，将清原县的土壤图、行政区划图、土地利用现状图进行叠加，确定24868个评价单元，采用模糊评价、特尔斐法、层次分析法对土壤管理、耕层养分状况、耕层理化性状、剖面性状4方面13个影响因子进行分析．并建立耕地地力评价体系。以期为合理利用耕地资源提供参考。

Based on the geographic information system （GIS）,using totally 5 587 points, overlaying the current landuse map with the administration map and the soil map,forming 24 868 patches,which are used as the basic management and evaluation cells. This research selected thirteen influencing factors from four aspects including land management, soil nutrient content, physical and chemical situation and profile situation, and the evaluation system and model of farmland fertility was build up. The grade of arable land productivity was formed according to the theory of Fuzzy Mathematics, Telphi Principle and Analytic Hierarchy Program,and the farmland fertility in Oingvuan country and analysis of its spatial distribution were evaluated.
