估算地下水补给量的新方法-SWATMOD耦合模型简介

Estimation of Groundwater Recharge by The New Method-SWATMOD Coupling Model Introduction

近年来,随着经济社会的飞速发展,生产生活用水量的迅速增加导致供需矛盾增加,地下水资源也被过度开采。为了避免过度开采地下水资源而造成严重的环境问题和更好地可持续开发和利用地下水资源,我们需要更为准确的估算地下水补给量。地表水与地下水存在密切联系。为了更好的掌握地下水与地表水的资源情况,地表水与地下水的耦合就十分重要。因此,SWATMOD耦合模型便应运而生,它是一种将地表与包气带水文过程与地下水流过程有机的结合在一起考虑的模型,能够提高地下水补给量估算的精确度。

In recent years, with the rapid development of economy and society, the water consumption of production and living Which is rapid increasing leads to the contradiction between supply and demand so that the groundwater is exploited. In order to avoid the serious environmental problems caused by over exploitation of groundwater resources and achieve the sustainable development and utilization of groundwater resources, we should search a more precise method for accounting the groundwater recharge. There is a close relationship between surface water and groundwater. In order to grasp the resources of groundwater and surface water, the coupling model between surface water and groundwater is very important. Therefore, the SWATMOD coupling model came into being. It is a kind of coupling model refer to surface and the vadose zone hydrological processes and groundwater flow process.It can improve the accuracy of estimation of groundwater recharge.
