地下水脆弱性评价是地下水环境保护与决策的有力工具,岩溶地区地下水脆弱性评价尚无有效方法.基于汇流、上覆岩层和降水等因素,以济南地区为例,对地下水脆弱性评价方法-COP法进行了较详细的介绍和应用,针对COP法存在的问题,提出了基于承压含水层埋深、水力传导系数、隔水顶板岩性和隔水层厚度4个因子的BCAT指标法评价承压区岩溶水的脆弱性.最后,指出地下水脆弱性评价方法的发展趋势.

The evaluation of groundwater vulnerability is a useful tool for groundwater environmental protection and decision-making, the karst groundwater vulnerability evaluation lacks an effective method. In order to assess groundwater vulnerability in karst areas. based on concentration flow, overlying layers and precipitation, COP Method is introduced in this paper and brought forward as a study case of Jinan karst spring regions. A DCAT index for antipollution evaluation of confined groundwater system is proposed a-gainst the problem that COP Method exists , the DCAT index includes depth to confined aquifer, Conductivity of the aquifer, cate-gory of aquiclude, and thickness of aquiclude. At last the paper analyzes the development trend of the research on groundwater vul-nerability assessment.
