摘要: 本文依据实测数据及有关资料, 对林冠截留进行了深入细致的分析, 并以物理化学中溶液吸附理论引伸出的上升-饱和函数关系曲线为类比, 提出了一组关于林内雨量率、截留率、截留量与大气降水关系的新的数学模型。模型中的3个参数μm、Po、k水文学意义明确, 拟合效果较好, 对深入研究林冠截留具有一定现实意义。

关键词: 大气降水, 林内雨量率, 截留率, 截留量, 上升-饱和函数关系曲线

Abstract: According to the observed data and relevant references, an in-depth analysis on the pro cess of canopy interception is given, and analogized with the curve of up-saturation function which based on the theory of solution adsorption in physicochemistry, a set of new models on the relationship between the rate of rain falling to the forestland, the rate of interception, the intercepted quantity and the rainfall outside the forest is presented. Three parameters μm、 P0 and k in the models have definite hydrological significance. As we compare the results from the model with observed data, the consistency is quite sati sfactory. And all of these would have some significance for further canopy interception researches.The formula of the rate of rain falling to forestland.

Key words: Rainfall outside forest, Rate of rain falling to forestland, Intercepted quantity, Rate of canopy interception, Curve of up-saturation function
