采用野外调查、取样和实验分析相结合的方法对云南省保山市西庄河山地流域内4种主要土地利用方式（林地、耕地、茶园、灌丛）的土壤理化性质进行对比研究，讨论了不同土地利用方式对土壤肥力的影响，结果表明，不同的土地利用方式对土壤肥力具有比较明显的影响：土壤有机质和全氮质量分数变化从大到小依次为灌丛＞林地＞茶园＞耕地；磷、钾元素表现为耕地＞茶园＞林地＞灌丛；土壤阳离子交换量表现为耕地＞茶园＞灌丛＞林地；盐基饱和度表现为耕地＞灌丛＞林地＞茶园；农业耕作活动对表层土壤物理性质影响明显。
The soil physical and chemical properties of four main land use types (forestland, farmland, tea garden and shrub) in Xizhuanghe Mountain Basin of Baoshan City, Yunnan Province were studied by field survey, sampling and experimental analysis. The effects of different land The results showed that different land use patterns had a significant effect on soil fertility: the order of the changes of soil organic matter and total nitrogen was shrub> forest> tea garden> Potassium showed as follows: cultivated land> tea plantation> woodland> shrub. The amount of soil cation exchange showed cultivated land> tea plantation> shrub land> woodland, and the basal soil salinity showed cultivated land> shrub land> Significant impact on the nature.
