科尔沁左翼后旗主要耕作土壤肥力的模糊综合评判

Fuzzy Comprehensive Evaluation and Judgement ofMaine Cropped Soil Fertility in Kezuohou County

本文扼要阐述了模糊综合评判的数学模型，以土壤基本性状及有机质、速效氮、速效磷、速效钾含量五方面的因素作参评因索建立模型，对科尔沁左翼后旗典型的和面积较大的耕作土壤肥力状况进行综合评判，并采用计算权重的方法，突出了限制性因素对土壤肥力影响。

This paper expounded a model of mathematics of fuzzy comprehensive evaluation andjudgement and established the model of mathematics of fuzzy comprehensive evaluation and judgement by using soil basic characters and contents of the organic matter quickacting nitrogen,quickacting phosphine and quickacting POtassium as evaluation and judgement indexes.This model wasapplied to fuzzy comprehensive evaluation and judgement of maine cropped soil fertility in kezouhou county and given prominence to effect of limiting factors to soil fertility by use of computing weight.
