本文选择集流面进行有机硅喷涂、拍光压实及自然坡面三种处理的刺槐林地，对其林地土壤水分动态变化作了定量分析，并探讨了其林木生长的差异，可为生产实践中径流林业的推广提供科学的理论依据。
In this paper, we selected the Robinia pseudoacacia forest land with organic silicon spraying, photo compaction and natural slope on the catchment surface to quantitatively analyze the dynamic changes of soil moisture and discuss the difference of the tree growth, which can be used for production practice To provide a scientific theoretical basis for the promotion of medium-sized stream forestry.
