该文通过林地土壤物理性质

土壤入渗率

林地枯落物吸水量测定和林地人工模拟降雨的地表径流观测

对密云水库上游人工林和天然次生林的水源涵养效益进行了比较系统的研究。结果表明:各树种具有明显的水源涵养效益

天然次生林的水源涵养效益高于人工林。并对土壤渗透时间与渗透速度

总渗透量的关系进行了曲线拟合

对影响林地地表径流系数的各因子作了逐步回归分析。

Abstract

The water-reserving benefits of man-made forest and natural secondary forest in the upper reaches of Miyunreservoir were systematically studied through determining the physical properties and infiltration of the soil

moistureholding capacity of forest litter and through observing the surface runoff produced by simulated rainfall. The resultsshow that each species of these trees has distinct benefits of water-reserving. The water-reserving benefits of naturalsecondary forest are higher than that of man-made forest. Using curve-fitting techniques

the relationship between thevelocity and time of soil infiltration and between the time and amount of that were given respectively. The runoff coef-ficient model of forest soil under simulated rainfall was developed with step by step regression.
