摘　　要：【目的】采用综合指数法对农五师89团耕地地力进行评价。【方法】以农五师89团为研究区,充分利用测土配方施肥项目取得的数据,收集整理相关图件和其它资料的基础上,结合特尔斐法、层次分析法、GIS技术等进行耕地地力评价。【结果】农五师89团耕地四、五级地所占比例较大,分别为28.64%、35.34%,一级地和六级地较少,不足总面积的4%,二级地、三级地分别占总耕地面积的13.70%和16.19%。【结论】农五师89团耕地大部分属于中等水平,中低产面积较大,要因地制宜科学合理种植规划。[ Objective] The purpose of this study was to evaluate the fertility of the cultivated land in the No. 89 state farm of the 5＇h Agricultural Division by using the integrated index method. [ Method] No. 89 state farm of the 5ts Agricultural Division was chosen as the research area and full use was made of the data obtained through Soil Testing and Formulated Fertilization Project, and related graphic documents and other information were collected, and then Delphi, Analytic Hierarchy Process, GIS technique etc. were used to evaluate the cultivated land＇s fertility. [ Result ] Cultivated land Grade four and five in No. 89 state farm account for a large proportion, that is, 28.64% and 35.34% respectively; Grade one and six take up not more than 4% of the total area; Grade two and three account for 13.70% and 16. 19% respectively. [ Conclusion] Establish the cultivated land fertility evaluation system.
