云县石佛山小流域坡耕地土地治理是云南省开展坡耕地水土流失综合治理工程试点之一。项目对西南高原地区坡耕地治理方法的推广具有典型意义。选取该典型区域对其土地治理过程中对土壤理化性质的影响进行分析、研究,并探寻一些坡耕地治理前后土壤理化指标在土壤肥力、重金属污染等方面的变化规律,为进一步坡耕地水土流失治理提供理论依据。
Land management of sloping farmland in Shifoshan small watershed in Yunxian County is one of the pilot projects of comprehensive management of soil erosion in sloping farmland in Yunnan Province. The project has typical significance for the popularization of slope farmland management in the Southwest Plateau. This paper analyzes the influence of the typical area on the physical and chemical properties of the soil in the process of land management and probes into the changing rules of soil physical and chemical indexes before and after the sloping land management in terms of soil fertility, heavy metal pollution and so on, Provide a theoretical basis.
