| 摘 要： | 从土壤的理化因子出发，利用综合评价的方法，对渝东地区城口县坪坝区大巴山南坡山地黄壤的土壤肥力变化特征与地上植被类型之间的关系进行了研究.结果表明，马尾松林、杉木林、落叶栎类林、茶树林和常绿阔叶林下土壤肥力的综合指标值分别为0.1256、0.2085、0.3514、0.2479、0.9329.阔叶林（落叶栎类林、茶树林和常绿阔叶林）下山地黄壤的土壤肥力综合指标值均大于针叶林（马尾松林、杉木林）下山地黄壤的土壤肥力综合指标值.即使在同一植被类型下，由于建群种的不同，其土壤肥力综合指标值也不相同.根据植物群落演替的过程可以断定土壤的发育与植物群落演替是两个密不可分、相辅相成的过程.

| Abstract: | Based on the analyses of soil physical and chemical properties,this paper studied the relationship between plant community succession and fertility variation of mountain yellow soil in east Chongqing.The results showed that the values of integrated soil fertility index of Pinus massoniana,Cunninghamia lanceolata,deciduous oak,Camellia sinensis and evergreen broad-leaved forest soils were 0.1256,0.2085,0.3514,0.2479 and 0.9329,respectively,implying that soil development had a close relation to plant community succession. |
