摘　　要：提出了树冠对降雨截留容量的概念,截留容量不仅反映树冠特征对降雨截留作用的大小,还可以用于不同林分之间的比较。通过对雪松树冠截留降雨的观测资料,近似确定出了雪松截留容量与降雨量的关系。借鉴水文学中"流域蓄水容量面积分配曲线"概念,建立了雪松截留容量与降雨量的半经验公式,给出了公式中3个参数的确定方法,经检验效果较好。Tree canopy interception rainfall capacity not only reflects the degree of tree canopy intercept rainfall features,but also it is used to compare interception capacity among different stands.By analyzing data of deodar cedar（Cedrus） canopy intercepting rainfall,a relationship between intercepting capacity and rainfall was established approximately.A half-experience formula was built according the concept of relative curve between watershed storage-water capacity and area in hydrology,and a method of determinating three parameters in formula was also introduced.The results were trust worthly through verification.
