模糊聚类分析在土壤肥力分类中的应用

土壤分类中涉及的许多指标具有模糊性,因此将模糊数学中的模糊聚类分析应用到土壤分类研究中,以期更准确、更合理地区分土壤类型.模糊聚类分析是根据模糊集的理论和方法,通过对样本各类指标的观察值进行数理统计分析处理,最终根据研究目的将各个样本集进行有效分类的一种多元统计方法.在介绍模糊聚类分析理论的基础上,运用模糊聚类分析方法对江汉平原后湖地区的土壤肥力进行分类,验证了该方法在土壤肥力分类中的可行性.

Application of Fuzzy Clustering Analysis in Classification of Soil Fertility

Since many fuzzy indexes are involved in soil classification,therefore,the fuzzy clustering analysis of fuzzy math is used to research the soil classification,so as to differentiate the soil type more correctly and reasonably.In terms of the researched aim,the fuzzy clustering analysis is a kind of multi-factor statistical method by statistics,analysis and processing of the observed values of various indexes based on the theory and method of fuzzy set to classify effectively each sample set finally.Based on the introduction of the theory of fuzzy clustering analysis,the study uses the method of fuzzy clustering method to classify the soil fertility of Houh area in the Jianghan Plain,and the feasibility of the method in the classification of soil fertility is verified.
