摘要
考虑由彼此间有间距的树冠组成的非均匀林冠内的降雨截留过程,将以前的林冠截留理论模型从水平均匀随机分布林冠推广到非均匀林冠,导出相应的偏微分方程和截留量的计算公式,并以实例运行该模型,以揭示非均匀林冠在降雨截留过程中的一些细节特征。
The process of rainfall interception by inhomogeneous forest canopy composed of tree crowns with some gaps among them has been considered, and the previous theoretical model of rainfall interception has been generalized from statistically homogeneous canopy to inhomogeneous canopy as well. Both the relevant partial differential equations and a formula to estimate rainfall interception were derived. Moreover, the new model is illustrated with typical values of some ecological factors, and some specific characteristics of interception process were shown.
