辽宁省中部平原降雨入渗补给系数分析

降雨入渗是地下水补给的主要来源， 其影响因素较多， 主要有土壤、地下水埋深、次降雨量及前期影响雨量。利用地下水动态井资料及降雨资料， 建立降雨入渗半理论半经验模型，并用统计分析方法计算不同质地土壤降雨入渗补给地下水模型中的系、指数， 在辽宁省中部平原地区地下水资源评价中应用，收到较好的效果。

Rainfall infiltration replenishment factor analysis at the plane in middle part of Liaoning province

The rainfall infiltration is a main source of groundwater recharge. But there are many influence factors, such as soil, bury of groundwater, amount of sub-rainfall and antecedent rainfall are primary factors. A semi-theoretical and semi-empirical model of rainfall infiltration replenishment was built up by the data from rainfalls and long-term observation wells for groundwater dynamic. For different soil texture, the coefficients and the power of numbers in the model were calculated by the statistical analysis method. The model was used in groundwater resources assessment at the plane in middle part of Liaoning province, and achieved good results.
