| 摘 要： | 基于欧洲模式中针对岩溶含水层脆弱性的评价方法—COP法,根据区内实际水文地质条件,建立徐州城市规划区岩溶水脆弱性评价模型。评价结果表明,脆弱性级别高区、脆弱性级别较高区占徐州城市规划区总面积的23.12%、13.73%;脆弱性级别中等区占总面积的7.85%;脆弱性级别较低区和低区分别占总面积的11.57%、43.73%。总体来看,区内岩溶含水层脆弱性整体较低,不容易被污染;脆弱性高区主要分布在基岩裸露区及其周围地区。

| Abstract: | Based on the COP method of European model for karst water vulnerability assessment,and according to the actual hydrogeological conditions in Xuzhou planning area,the karst water vulnerability assessment model has been established.As a result,the areas with the highest and higher vulnerability account for 23.12%and 13.73%,while the area with medium vulnerability accounts for 7.85%in Xuzhou planning area.The areas with lower and lowest vulnerability account for 11.57%,43.73%,respectively in Xuzhou planning area.Overall,the vulnerability of karst water aquifers in Xuzhou planning area is low and it is safe from pollution.The bedrock exposed region and its surrounding area is much more vulnerable. |
