摘　　要：将有机碳、全氮、全磷、全钾、碱化度、pH等项目作为评价指标,应用灰色关联度分析方法,对均腐土28个土系进行综合评价,结果表明,名文系等8个均腐土土系关联度达到0.60以上,比其它土系的关联度要高,关联度在0.39以下的为白音讷勒系。灰色评价方法得出的结论与实际情况基本一致。SOC, total N,total P, total K, ESP and pH were chosen as main indices for evaluation and the gray relative analysis was used to evaluate twenty- eight series of Isohumisols. The results showed that Grey relation coefficients of eight Isohumisols such as Mingwen Series were more than 0.60, and it was more than the other Isohumisols. The gray relation coefficients which was less than 0.39 was Baiyinnele Series. The results from the gray relative analysis get the same way with the nature.
