摘要
本文以相关分析法选取并确定了土地鉴定因素及其权重,以最大树法进行了模糊聚类分析,在此基础上确定了各鉴定因素的隶属函数,作出了模糊综合评判模型,通过评判模型确定土地的质量等级。
The identification factors were selected out by correlation analysis.The maximum tree method was used for fuzzy cluster analysis and then the sub-functions of each identifica- tion factor were formulated.Finally,the fuzzy comprehensive evaluation model was estab- lished with which the grades of apple orchard soil could be determined.
