摘要
在总结海平面变化及长江三角洲古河道分布的基础上,通过上海地区第Ⅱ至第Ⅴ承压含水层地下水化学、^(14)C年龄特证的分析,探讨了因海平面变化引起的长江及支流河道的侵蚀、堆积对地下水径流交替的影响,提出了滨海三角洲地区地下水补给、径流、排泄的一种模式。
Based on a review of historical sea level changes and fossil stream channel distribution in the Yangtze River delta, the authors have studied the influence of erosion and accumulation of the Yangtze River and its tributaries caused by sea level changes on groundwater recharge, runoff and discharge through analyses of chemical and 14C age characteristics of groundwater in aquifers Ⅱ , Ⅲ , Ⅳ and Ⅴ . A groundwater recharge, runoff and discharge model in a littoral delta is proposed in the paper.
