摘要
摘要:本文旨在利用因子分析方法和模糊数学中的隶属度函数,对天津市经济技术开发区土壤肥力进行定量化的评价。文中首先对开发区土壤现状进行了分析,然后应用SPSS软件确定土壤中各个因子的评价指标的权重,并且计算各个指标的隶属度,最后得出土壤综合肥力指标。
This article is for the purpose of using factor analyses method and degree of membership function in fuzzy mathematics to evaluation quantitatively on TEDA soil fertility.Firstly,the author had carried on the analysis to the TEDA soil situation presently,and then identified each factor＇s weight and degree of membership with the help of SPSS.Finally this paper obtained integrated fertility index（IFI） of TEDA.
