摘    要:根据黄土高原水土保持世行贷款项目的部分监测数据 ,分析了水土保持措施对土壤肥力的影响。结果表明 ,水土保持措施实施以后 ,土壤含水量增加 ;土壤容重降低 ,孔隙度增大 ,改善了土壤结构 ;土壤养分含量和阳离子代换量增加。

关 键 词:土壤  结构  含水量  养分  阳离子代换量  水土保持  黄土高原

Abstract:Based on partial observation data of soil and water conservation of World Bank's Loan Project on the Loess Plateau, the effect of soil and water conservation measures on soil fertility was analyzed.The results showed that the soil water content increased, soil unit weight reduced, soil porosity raised, soil structure was reformed, the contents of soil nutrients were higher,cation exchange capacity (CEC) increased after taking the soil and water conservation measures.
Keywords:Soil  Structure  Water content  Nutrient  Cation exchange capacity  Soil and water conservation  Loess Plateau
