摘要/Abstract

摘要： 针对大连市周水子地区滨海含水层的海水入侵状况，建立了一个非均质各向异性介质的三维变密度地下水数值模型．利用实际观测水位和浓度资料对模型进行校正和检验，以识别研究区含水层的水文地质参数．再利用校正和检验模型预测在考虑潮汐作用的条件下，研究区未来30年的海水入侵发展状况．预测结果表明，潮汐作用会加重研究区的海水入侵程度．本文模拟分析成果可为控制大连滨海地区海水入侵、实现地下水资源的合理配置提供理论依据．

Abstract: This study develops a threedimensional heterogeneous densitydependent numerical model to simulate the seawater intrusion process in coastal aquifers in Zhoushuizi District，Dalian City.To identify the hydrogeological parameters of the aquifers in the study area，the model was calibrated and validated using the observed head and concentration data.According to the current groundwater abstraction conditions in this study area，the calibrated and validated model was applied to predict the dynamics and trend of seawater intrusion for the following 30 years from 2010 to 2040 with and without tidal effect.Prediction results showed that the overall extent of seawater intrusion in the future would be even more severe considering tidal effect.This threedimensional seawater intrusion model provides the theoretical basis for controlling the further deterioration of groundwater quality and the rational allocation of groundwater resources in coastal aquifers.
