摘　　要：以多维利用雨水资源为目的,针对研究区坡面、沟道等不同的自然地貌条件,研究建立主动利用和被动利用雨水资源的两种开发模式,并通过示范区试验,初步实现人工有限干预水文循环的效果:改善灌溉条件,改良土壤成分,提高粮食单产;促进产业结构调整,稳定农业效益;调控坡面与沟道径流,减少水土流失。For the purpose of multiple utilizations of rainwater resources,this paper puts forward two development modes of the active utilization and passive utilization of rainwater resources,based on the natural geomorphic conditions of slopes and ditches in the study area.Through experiments in the demonstration area,the following effects of limited manual intervention on the hydrological cycle were preliminarily achieved： improvement in the irrigation conditions,improvement in the soil constituents,increase of the crop yield per unit area,promotion of the industrial structure adjustment,stabilization of the agricultural benefits,regulation of runoff along the slopes and in the ditches,and decrease of soil and water losses.
