摘　　要：地下水环境保护的关键工作之一是保护地下水型饮用水水源.为了科学保护水源地,须划定水源补给区.以郑州市的九五滩水源地为例,对不同傍河型水源补给区划分方法进行对比分析,并最终划定了九五滩水源补给区.结果表明,傍河型水源补给区宜结合水文地质分析法和数值法结果综合划定,河流侧向补给边界、隔水边界根据水文地质分析法结果确定,其他流量边界根据数值模型预测水源井相应时间的捕获区范围确定.九五滩水源补给区的北部边界位于黄河河道的北岸,西部边界为京广线铁路,东部边界为郑州黄河公路大桥,南部边界为沿黄快速通道,补给区面积为62.17 km^(2).研究结果可为该水源地地下水保护提供科学依据,也可为其他傍河型水源补给区划分提供参考.Protecting groundwater-based drinking water sources is a fundamental aspect of groundwater environmental preservation.The division of groundwater recharge zones forms the basis for ensuring the safety of drinking water sources.This work comparatively analyzes the combination of optimal division methods for riverside groundwater recharge areas and uses it to devise groundwater recharge zones for the Jiuwutan water source.The results indicate that the recharge area of the riverside groundwater source should be comprehensively divided using hydrogeological analysis and numerical methods.The lateral recharge boundary of the river and water barrier boundary should be determined through hydrogeological analysis,while other flow boundaries are determined based on the capture area of the corresponding wells using a numerical model.The northern boundary of the Jiuwutan water source is the north bank of the Yellow River,while the western boundary is the Beijing-Guangzhou railway,the eastern boundary is the Zhengzhou Yellow River Highway Bridge,and the southern boundary is the Yellow River expressway.The total recharge area covers an area of 62.17 km^(2).The research provides a scientific basis for protecting groundwater in drinking water sources and offers a reference for the division of recharge areas for other riverside groundwater sources.
