摘　　要：为了评价川西北绵阳地区的农业土壤肥力质量,为该地区土壤平衡施肥,提高肥料利用率提供科学依据,选择四川绵阳青冈、关帝2个行政村为项目工作区,以金土地项目实测数据为基础,采用聚类分析法对样品分类,并引入AHP法和建立模糊综合评价模型,在确定参评因子后获取研究区内各因子权重的方法对项目研究区的农业土壤肥力状况进行评价。结果表明:关帝村的土壤肥力以4级(养分缺乏)为主,占81.5%;其次为3级(适量养分),占18.5%。青冈村则以3级为主,占81.1%;其次为4级,占18.1%。In order to evaluate the soil fertility in Mianyang district in Northwest Sichuan, Qinggang and Guandi villages were selected as study areas. Soil fertility situation has been assessed on the basis of determination the factors and acquired their weight, relying on the measured data from the golden land project, clustering analysis methodology was applied for sample classification, and AHP method were induced. The result shows that soil fertility in Guandi is mainly graded as class IV （nutrient deficiency）, accounting for 81. 5%, and followed by class III （moderate nutrients）, covering 18. 50%. While in Oinan is graded major in class III （81.1%）, and followed by class IV （18. 1%）.
