中文摘要在雨养农业区,土壤水占总降水量的60%~70%;若在作物参与下有80%降水都转化为土壤水,而土壤水是作物的直接水源,是降水资源化的最有效形式。坡地表层50cm的土壤水分变化直接影响降水径流的形成,从而决定降水利用率的高低。土壤水分变化和降水产流机制是降水资源的理论基础。依据农田水量平衡原理,采用合理的雨水利用方法,使降水资源最有效地直接贮藏在土壤水库中或间接的形成土壤水,以实现土壤水资源的可持续利用。
英文摘要Soil water was the core of the field water balance and the pivot joint of conversion for the three kinds of farmland water (overland flow ,soil water and groundwater) 160 % - 70 %precipitation was converted into soil water ,which was the most available water for crop utilization under the rainfall fedregion,and the amount might rise to 80% under crop growing farmland1The variation of soil water under 50 cm of hillslope surface directly influenced the conversion of rainfall into overland flow to decide the efficiency of the rainfall usage1The prior condition for rainfall resources exploitation was to make clear the rainfall2infiltration runoff mechanism, and based on the field water balance principle ,the proper rainfall utilization method was used to store as much precipitation as possible into the soil reservoir and promote the sustainable use of the soil water resources。
