【摘要】 我国北方地区地表水资源相对较少,因而地下水环境保护尤为重要。城市供水水源主要来自松散孔隙水分布区和岩溶裂隙水分布区,山区小流域为平原区地下水的补给水源,同时地层岩性多为砂卵砾石,防护能力较差。因此,应结合各地的实际情况,采取相应的水环境保护措施保护地下水资源。更多还原

【Abstract】 Surface water resources is relatively less in northern part of China, thus groundwater protection is of great importance. Water sources for urban water supply are mainly from friable fracture water distribution area and karst sources. Small watershed in hilly areas is the supplementary water source for groundwater in plain areas, while most of the stratum rocks are sandy gravel that has low protection capacity. Therefore relevant protection measures should be adopted in line with the actual local conditions.更多还原
