  2. Abstract : according to the base flow separation results from hydrographs in many watershed, the best regression equation expressing the relationship between annual precipitation infiltration coefficient and the weight of different strata area to total area of the watershed is established. the equation can be used to calculate the precipitation infiltration recharge for different ground water basins in which the strata distribution and the precipitation are given. the precipitation recharge is equivalent to the ground water recharge in some mountainous area where the exploitation of ground water resources are far from being sufficient

    文摘:降水入滲補給系數與地層相關分析的目的,是為推求山丘區降水入滲補給量.魯中山丘區是由各種不同地層出露組成的山丘區域.在多個水文流域基流分割基礎上,建立流域年均降水入滲補給系數與各種地層出露面積占流域總面積權重間的最佳回歸方程,利用該回歸方程和地層分佈及降水量推算不同地下水流域的降水入滲補給量.在地下水開發利用不高的山丘區,降水入滲補給量即為地下水補給量
