萨克模型在变质岩山丘区“三水”转化关系研究中的应用

APPLICATION OF SACRAMENTO MODEL IN THE STUDY OF RELATIONSHIP BETWEEN SURFACE WATER AND GROUND WATER IN METAMORPHIC ROCK MOUNTAINOUS AREA

本文选用山东胶东半岛代表性小流域试验资料,根据美国萨克拉门托流域水文模型,分析了变质岩山丘区地表水—土壤水—地下水的转化关系。以降水、实测径流、蒸发资料作为模型输入,应用计算机计算,计算结果与实测数据拟合良好。确定了形成河川径流的地面径流、壤中流、地下径流的定量分配关系。对变质岩山丘区“三水”的蓄泄关系及年内、年际变化进行了分析研究。计算结果分析表明,萨克模型可在同类地区“三水”转化关系及区域水资源评价计算中应用。

In this paper,the Sacramento model has been used to analyse the relationship between surface water and ground water.Hydrological data from the typically small watershed in the metamorphic rock mountainous area of the Jiaodong Peninsula,Shandong Province,have been analysed on the computer AST386.with the precipitation,runoff, evapotranspiration demand as input and with the streamflow,which includes surface runoff,inter flow,primary base flow and supplemental base flow,evaporation and soil moisture on the daily basis as output,the computed results tally with observed data.Therefore,the quantitative distribution relationship has been determined among surface runoff,inter flow and base flow,which form the streamflow.The storage-draft relationship among surface water,soil water and ground water of metamorphic rock mountainous area and the variations among precipitation,runoff,evaporation,soil moisture within a year or years have been disscussed in detail.The computed results show that the Sacramento model can be used as in the transfering relationship between surface water and ground water but also a method of evaluating regional water resources in areas of similar conditions.
