作者用模糊集隶属度与模糊集贴近度的方法对浙江省海涂土壤作定量分类。结果表明:该方法没有发生错判,方法本身具有的可靠性好,同时应用这种方法还发现了原土壤分类中有误的一些剖面。与多元统计中的判别分析比较,模糊集隶属度法更为简便,也更符合土壤分类需要。因此文中认为可用模糊集隶属度与模糊集贴近度来定量判断土壤的归属及表示土壤类型之间的相互关系。 The authors classify the tideland soils of Zhejiang Province by fuzzy membership and fuzzy proximity. The results show that the method has no misjudgment, and the method itself has good reliability. At the same time, this method also found some sections of original soil classification error. Compared with the discriminant analysis in multivariate statistics, fuzzy set membership method is more simple and more suitable for soil classification. Therefore, we think that fuzzy set membership and fuzzy set proximity can be used to quantitatively judge the relationship between soil attribution and soil type.
