【摘要】 在２２种土壤腐蚀性因素的聚类分析的基础上，通过对单个因素分类能力的特征评价，从同类中选取关键性因素，进而在特征空间中进行有关样本的土壤腐蚀性预测和考评，为今后土壤腐蚀性研究中主要因素的选取和等级评判提供一定的依据。更多还原

【Abstract】 On the basis of the clustering analysis of corrosive factors of soil, the abilities of corrosive factors to distinguish soil corrosivity are assessed, and the main factors are selected,In the generalized space of the main factors,the disposition of the nearest neighbors for the experimental samples are analyzed and the way to predict the soil corrosivity for unknown samples is studied.更多还原
