黄土高原地下水资源与水质初步评价
Water resource and water quality evaluation of underground water in Loess Plateau
【摘要】 通过黄土高原地质、地貌及水文钻孔资料的初步分析 ,认为 :该地域地下水的分布、赋存层位、水质、富水程度等主要受地貌、地质构造、岩性、气候及水文等条件控制 ;其中松散岩类等裂 (孔 )隙水以大气降水补给为主 ,多数以泉水形式排泄于沟谷中。结合降水量、排泄方式及矿化度的不同 ,对各种成因地下水进行了综合水质评价 ,得出该区域潜水地下水大部分为重碳酸型低矿化度淡水 ,矿化度大于 1 g/L的微咸水、咸水主要分布在宁夏银北、西海固地区和甘肃陇西及内蒙古河套地区 ,为高原水资源开发利用提供了水文地质资料
【Abstract】 Based on the geological and geomorphic features ,and the principium analysis of hydrogeologic drilling data, it shows the distribution ,host position ,water quality are mainly controlled by geomorphology ,geological structure ,lithologic characters ,weather and drainage characteristics,in which the pore water of loosened rocks is replenished with precipitation ,and drains into trenchs as spring .Combining with precipitation, drainage pattern and nineral intensity ,the undergrourd water quality on many genetic types is comprehensively evaluated.It provides useful hydrogeologic data for the exploitation and utility of water resource in Loess Plateau.
