中文摘要：

从土壤理化性质出发，利用多元统计方法和土壤肥力综合评价体系，对新疆喀纳斯旅游区森林群落次生演替过程中土壤肥力的变化特征进行了综合评价。结果表明，不同森林类型的土壤肥力综合指标值为阔叶林〉阔叶针叶混交林〉针叶阔叶混交林〉针叶混交林；不同森林演替阶段的土壤肥力综合指标值为演替前期〉演替中期〉演替后期。

英文摘要：

Based on soil physical and chemical properties, the variation characteristics of soil fertility at different succession series of the forest communities in Kanas Tourist Areas was evaluated by the integra- tive evaluation system. The result showed that the descending order of the integrated index value of soil fertility among different forest types was as follows： broad-leaved forest〉broadleaved-needleleaved mixed forest〉needleleaved-broadleaved mixed forest〉 needleleaved mixed forest. The descending order of soil fertility among different succession series was as follows： the earlier stage.the middle stage.the later stage.
