【摘要】 本文论述了塔里木河生态脆弱区渭干河灌区地下水水文地质、赋存、补给、径流、排泄特征、化学特征和地下水动态变化特征。灌区地势北高南低决定了地下水的基本流向,地下水主要以地表水转化补给为主,灌区地下水表现为渗入-蒸发型的动态特征,年际变化小,现状地下水仅有少量生活用水开采,开采量很小,水质较好,满足集中式生活饮用水水源及工、农业用水要求。科学认识该区地下水特征,对该区地下水开发、保护、治理以及调配流域和区域水资源保障供水安全、生态与环境安全和地下水资源的可持续利用政策的实施提供了科学依据。更多还原

【Abstract】 This paper discusses the groundwater characteristics,including hydrogeology,storage,recharge,runoff,discharge,chemical characteristics,dynamic changes,et al.In the Weigan River irrigation area of Tarim River in Xinjiang.In the Weigan River irrigation area,the terrain slope decides the flow direction.The groundwater is mainly recharged by the surface water.Its dynamic characteristic is filtering-evaporation type,with a little interannual change.The volume of groundwater exploited is small and the quality of the water is fairly good.It is vital to exploitation,protection and control of groundwater to understand its characteristics,which can provide a scientific basis for sustainable utilization of groundwater resource.更多还原
