对干旱半干旱地区地下水资源的特征 ,地下水的水文地质条件及相关的水文地质问题进行了分析 ,阐述了干旱半干旱地区地下水资源的利用现状及地下水资源管理的内容和意义。
One third of the land area belong to arid or semi-arid regions in the world,and many countries,about a half,are impacted by some problems caused by aridity in certain ways,such as prostration of aquifers,deterioration of water quality,desertification,and soil salinization or alkalinization.Generally there are seldom perennial rivers and freshwater lakes in arid regions because of less precipitation and surface runoff and strong evaporation.Many countries are facing a severe shortage of water along with population growth,increase of water consumption for irrigation,aggravation of water pollution,deficiency of investment on water resources,etc.This paper analyzes the characteristics of the groundwater resources,hydrogeologic conditions and related hydrogeologic issues of groundwater in arid and semi-arid regions,and also discusses the present situation of utilization,content and significance of management of the groundwater resources in arid and semi-arid regions.
