摘　　要：结合历史时期的海水入侵监测数据,对大连市典型海水入侵区大魏家地区50余年海水入侵历史演化过程进行了分析。基于近期地下水采样测试数据,评价了当前地下水供水的生活饮用水和农业灌溉水的适宜性。在此基础上,从自然和人类活动两个方面对该区地下水质情势和影响水质的主控要素进行了分析和判别。结合目前地下水开发利用现状,提出了地下水开发利用针对性对策。研究结果为该区供水安全和地下水合理利用提供了科学依据。Based on the long-term monitoring data of seawater intrusion in the past 50 years,the historical evolution of seawater intrusion in Daweijia area,a typical seawater intrusion area in Dalian,was analyzed.On the basis of the recent sampling and testing results,the suitability of current groundwater supply for drinking water and agricultural irrigation water was evaluated.Furthermore,the groundwater water quality situation and the main controlling factors affecting water quality in this area were analyzed and discriminated from two aspects of natural and human activities.According to the current situation of groundwater exploitation and utilization in this area,the corresponding countermeasures were put forward.This study results provide a scientific basis for the safety of water supply and rational utilization of groundwater in thisarea.
