摘要
南通市地下水主采层Ⅲ承压水为赋存于第四系地层中的松散岩类孔隙水,已成为区内广大乡镇水厂的主要供水水源,全区性开采。1998年完成的《南通市地下水资源评价报告(1∶10万)》,为水资源主管部门地下水规划管理的依据。以1997年为基准对比年,阐述1997年以来区内地下水主采层水位动态的演变特征,为加强地下水资源的规划管理,保护地质环境提供一定的依据。
The Ⅲ confined groundwater belongs to a kind of porous water buried in the loosened rocks of Quaternary formations and has become the major water supply in the region. Based on the year of 1997 as benchmark contrast, the author depicted the dynamic evolution properties of the main extraction layers for the underground water in the region since 1997, providing foundations for the supervision and planning of water resources and environmental protection of the region.
