应用层次分析法、隶属度函数和森林土壤健康指数法，对吉林省蛟河市林业实验区管理局内4种不同演替阶段的森林土壤健康进行评价；主要选取5个物理性指标、8个化学性指标、1个生物指标建立评价体系，使用隶属度函数进行无量纲化处理，应用层次分析法求出各指标的权重值，得出森林土壤的健康指数。结果表明：森林土壤健康等级降幂排序为中龄林、成熟林、老龄林、近熟林；相关性分析可知，土壤健康指数，与全氮、有效磷、速效钾呈极显著相关性，与水解氮、有机质呈显著相关。

We used analytical hierarchy process , standard scoring functions and forest soil health index to evaluate the health of forest soil at four sucessional stages in Jiaohe Management Bureau of Forestry Experimental Area in Jilin Province .We se-lected five indexes of physical properties , eight indexes of chemical properties and one biological indicator to establish the assessment indicator system .The standard scoring functions were used to process dimensionless , and the analytical hierar-chy process was used to calculate the index weight , and finally the health index of forest soil was obtained .The descending order of forest soil health level was middle-aged forest, mature forest, old-growth forest, and near-mature forest.By the correlation analysis , the correlations between health index of forest soil and total nitrogen , available phosphorus , and avail-able potassium were highly significant , and health index was significantly correlated with available nitrogen and organic matter.
