摘要

以四川盆地西缘中低山坡地为研究样地，根据实际地貌特征分别选取3个典型山体、2个典型土壤类型。山体坡面不同坡位下土壤质量综合指数（PI）研究表明土壤质量指数随山体坡面位置相对海拔高度的降低而增高。不同利用方式下土壤质量综合指数（QI）研究表明，人工林的土壤质量指数值显著偏高，坡耕地的指数值最低。中低山坡地土壤质量的变化特征主要依赖于土地利用与覆盖之间的差异。故必须加强坡耕地规范治理，实施植被保护与重建等一系列土壤资源持续利用措施，实现土壤质量的持续健康发展。

Abstract

This essay takes middle-low mountains in the western edge of Sichuan basin as the research area

and selects three typical mountains and two soil types according to the practical geomorphic features.The research of the composite index number(PI) of soil quality in different soil locations suggests that

the soil quality index increases as the altitude of mountain slope location decreases.The research of the composite index number(QI) of soil quality in different utilizing ways suggests that

of forest plantation is obviously higher

whereasof sloping cultivated land is the lowest.The distribution configuration of middle-low mountain soil quality mainly depends on the variations between land use and cover

and human activities is the main factor that enhances the variations.So if the stable positive circle of mountain ecosystem and the sustainable development of soil quality are to be realized

a series of measures to improve soil quality and recover ecotope

such as reinforcing the treatment of farm land on the slope

enhancing constructions of the projects of vegetation conservation and protection.
