本文采用模糊(FUZZY)聚类分析的方法,对实例21组数据的11项土壤肥力因素进行聚类筛选,确定了6项有代表性的土壤肥力参评因素,并以此对土壤肥力进行评价。其结果比原有11项肥力因素的评价结果提高了对作物产量的相关程度。这6项因素是:有机质、速效氮、胡富比、转化酶活性、容重和全钾。
In this paper, FUZZY cluster analysis method was used to cluster 11 soil fertility factors in 21 groups of data, and 6 representative soil fertility parameters were determined, and soil fertility was evaluated. The results of the evaluation than the original 11 fertility factors increased the relevance of crop yield. These six factors are: organic matter, available nitrogen, Hu Fu ratio, invertase activity, bulk density and total potassium.
