Fuzzy聚类分析在土壤分类中的应用研究

Study on the Application of Fuzzy Clustering Analysis in the Soil Classification——Example for the Mountain Soil in Fujian

应用模糊聚类分析方法,以福建山地土壤为例,进行土壤分类研究。首先对20项土壤理化特征在计算机上进行Fuzzy聚类筛选,确定粘粒交换量、阳离子交换量等12项有代表性的土壤指标为分类指标。并据此对福建山地土壤进行分类,将其分为草句土、黄壤、草甸黄壤、红壤、黄红壤、红黄壤和变性土7个类型。同时提出了分类鉴别方法——加进标准样本的Fuzzy聚类分析法和福建山地土壤分类鉴别的计算机软件。研究结果表明,Fuzzy聚类分析法在土壤分类中是一种切实可行的方法。

This paper reports that applying the method of Fuzzy clustering analysis to the study of the soil classification, example for the mountain soil in Fujian. 20 physics and chemical items of the soil characteristic are clustered and selected by the method of Fuzzy clustering analysis and computer. 12 items of the soil characteristic are selected as the representative soil classification indexes. Seven types of the mountain soil in Fujian are classified. A advisable method for the soil classification——Fuzzy clustering analysis with the standard sample is suggested.
