降水入渗补给系数分析研究

Analysis and Study on Recharge Coefficient of Precipitation Infiltration

本文运用均衡实验站各观测系统的实验数据和资料,根据水均衡原理和“三水”转换关系,通过包气带蓄水库容有效作用分析,阐明了包气带蓄水库容和复蓄的概念,说明了包气带对土壤中水分调节作用的机理。通过对前期影响雨量系列的分析,建立了降水与入渗补给系数之间的关系,得出了降水入渗补给系数计算思路和取值公式,同时就降水入渗补给系数和地下水埋深的关系进行了探索。

Based on the experimental data and information of observation system from the water balance experimental stations and the water balance principle and relationship of triple-water circle, by analyzing the effective function of storage capability of the zone of aeration, the article states the concepts of water-storage and re-storage of zone of aeration and described the mechanism of the moisture-regulated function by the zone of aeration of soil. Through the analysis for precipitation series information, it sets up the relationship between precipitation and infiltration recharge-coefficient and concludes the calculation logic and evaluation formula of precipitation infiltration coefficient, at the same time, it searches the relationship between recharge coefficient and groundwater depth.
