摘  要：
对太行山低山丘陵区坡地人工刺槐林降雨入渗及造林技术研究结果表明,降雨后短时间内(10~30cm)上层剖面水势很快由初始值增至最大值,当降雨停止后水势逐渐降低。随入渗进行而下渗锋面向下扩展,水势分布曲线由较陡直逐渐变为相对平缓。降雨初期有林地入渗速率慢于无林地,随降雨进行有林地入渗锋前移速率明显快于无林地,有林地植被及枯落物的存在阻缓了地表径流和壤中侧向流,增加了垂直一维入渗。

摘  要：
Rainfall-infiltration processes under artificial Robinia pseudoacacia plantation and afforestation technology in the slope of low-land in Taihang Mountains were studied.The results show that the water potential in 10～30cm soil section quickly increases to maximum with rainfall and decreases gradually after rainfall stops.With infiltration,the wetting peak gradually moves ahead.Curve of water potential changes from steep to slow.Comprising the water potential variation in different vegetations,infiltration velocity is slower in forest land than that in naked land at the beginning of rainfall.With rainfall going on,the speed of wetting peak moving ahead in forest land is quicker than that in naked land.Litters and vegetations slow down the lateral and subsurface flow and increase the one-dimensional vertical infiltration.
