降水对土壤水资源的补给及其制约因素分析

Analysis of water resources supplement in soil from rainfall and constraint factors

阐述了土壤水资源的概念及其内涵,分析了降水对土壤水资源的补给。通过实验,对降水特性、土壤含水量、土壤特性、地下水位埋深、季节性和区域性因素进行了分析,给出了制约降水补给土壤水资源各因子的定量或定性结论,为农业生产中有效利用土壤水资源提供了科学依据。

The paper elaborated the concept of soil water content and analyzed the soil water supply from precipitation.Through experiment,the precipitation characteristics,soil moisture,soil characteristics,groundwater depth,seasonal and regional factors were analyzed.It given the quantitative or qualitative conclusions of every factor to constraint the soil water recharge from precipitation.The paper provided a scientific basis for agricultural production efficient use of soil water.
