【摘要】 通过对太行山典型区径流小区内不同覆盖处理和坡度处理对土壤水运动的影响的试验研究,探讨了山区土地利用方式和人为耕作活动对土壤水的影响。结果认为人为的耕作活动对山区降雨入渗有很大影响。自然坡面未进行人工处理截留和覆盖时,降水到达地面后主要以产流的形式流走,而难以入渗到30cm以下土层。石子覆盖的坡面将延长雨水滞留时间而促进入渗,但水平地面的作用不明显。工程措施处理可以改变降雨入渗的特性,有效地将雨水集流储存到深层土壤。更多还原

【Abstract】 By the experimental studies on effects of mulching methods and slope treatments on moving processes of soil moisture in typical runoff plots in Taihang Mountain region,the effects of types of land uses and farming activities on soil moisture in this region are interpreted.The results show that precipitation- infiltration process is impacted significandy by fanning activity.It is hard to infiltrate into 30 cm and more for natural slope where no catching measures and mulching are carried out and net precipitation will collect and runoff.Mulching by little stone in diameter of 5- 20 mm in slope helps to extend the retention interval and to accelerate infiltration.However,it is not significant in horizon plot.Moreover,engineering measures will effect the infiltration characteristics of precipitation and promote die precipitation storing into deeper depth.更多还原
