摘要

摘要: 从可持续角度提出了区域地下水资源属性的概念; 分析了含水层系统中地下水质点的时间效应; 利用大量同位素资料分析了不同区域含水层系统中的地下水资源属性和人类活动对地下水资源属性的影响.指出利用环境同位素是研究区域地下水资源属性最直接、有效的方法; 正确认识评价区域地下水资源属性对实现地下水资源可持续性具有重要意义.

Abstract: The paper put forward a concept of regional groundwater resources attribute from point of sustainability based on isotope information. It analyzed the distribution of groundwater age in the aquifer system, groundwater resources attribute in some regional aquifer systems using isotope data and the effect of human activities (groundwater exploitation) on regional groundwater resources attribute. It point out that the direct and cost effective tool for assessment of regional groundwater resources attribute is environmental isotopes, and correct recognition and estimation of regional groundwater resources attribute will play a very important role on realizing groundwater resources sustainability.
