摘要
本文对坡地林农复合系统水文效应进行的研究结果表明，复合系统中林地土壤非毛管孔隙对降水的有效调蓄能力比荒草坡强；全年除了３月、５月外，复合系统农地土壤含水量均比对应的纯农地略高；采用横坡聚土垄作或土石护坎工程可有效地减少复合系统农地水土养分的流失量。
おhis paper studied the hydrological effect of agroforestry systems on slope.The results showed that the water storage capacity of noncapillary pores in forest soil of agroforestry systems was higher than that of the waste land.In a year except March and May,soil moisture content of farm land in agroforestry systems was higher than that of pure farm land.The amount of soil,water and nutrient losses of farm land in agroforestry sysem was reduced by contour tillage or engineering measures with stone banks.
