摘　　要：从土壤物理、化学和生物性质出发,通过土壤肥力综合指标体系,利用多元统计方法,对重庆缙云山亚热带常绿阔叶林不同演替阶段山地土壤肥力的变化特征进行综合评价。并分析了缙云山亚热带常绿阔叶林群落演替与山地土壤肥力变化的关系。In this paper, the variation characteristics of soil fertility at different succession stages of the plant communities in Jinyun Mountain, Chongqing City was evaluated, based on the soil physical, chemical and biological properties, and with the integrative evaluation index system. The values of integrated soil fertility index of shrub, coniferous forest, coniferous and broad-leaved mixed forest, evergreen broad-leaved forest were 0.0086, 0. 3407, 0. 5104 and 1, respectively, implying that soil fertility was improved with succession, and plant community played an important role in the development process of soil. The variation of soil fertility also affected the adaptability of species to environment and the competition among species. It was suggested that soil fertility was the important factor affecting plant succession course.
