摘要: 实验发现,降雨通过林冠的穿透过程线、树干径流过程线与电感电容电阻串联电路暂态过程线极为相似.由此启发,用此电路暂态方程拟合穿透降雨与树干径流过程并求出了解析解.进而,根据余项法求出截留强度表达式.此举拓宽了森林水文学理论研究思路.

Abstract: It is found through analysis that the throughfall and stemflow processes in canopy bear a strong resemblance to the transient course of series connection circuit of inductance capacitance and resistance. Thereform, an analytic result in terms of circuit transient equation and fitting throughfall and stemflow processes is obtained. Finally, the expression of interception intensity is obtained by means of remainder method.
