摘    要:介绍了大连市海水入侵现状及产生背景;针对国内外沿海地区普遍存在的海水入侵问题,分析了实践中广泛采用的单位脉冲-水位降深响应矩阵在解决海水入侵问题中存在的不足,阐述了建立单位脉冲-海水入侵响应矩阵的必要性和可行性。以大连市地下水资源开发为实际背景,分别建立了沿海边界节点的单位脉冲-海水入侵响应矩阵和研究区内部节点的单位脉冲-水位降响应矩阵,并使二者与地下水水流模拟模型相结合,构造了地下水系统优化管理模型,根据大连市地下水资源的发现状提出了2个方案的优化管理,可指导大连市未来的地下水开发;该模型还可用于解决国内外沿海地区类似的海水入侵问题。

关 键 词:地下水 海水入侵 管理 响应矩阵 地下水资源

Abstract:This paper gives a sketchy introduction to the current status and background of saline intrusion in Dialian City. According to the common problem of saline intr usion existing in the coastal areas around the globe and problems in the model o f response-matrix of groundwater level draw-down corresponding to unit pulse w hen it is used to deal with the problem of saline intrusion, it details the nece ssity and possibility of the establishment of response-matrix of saline intrusi on corresponding to unit pulse. Based on the actual practice of groundwater deve lopment of Dalian City, this paper develops two response matrixes: matrix of uni t pulse to saline intrusion at boundary nodes of computation groundwater area al ong the coast and that of unit pulse to groundwater draw-down at internal nodes . After the combination of these two matrixes with simulation model of groundwat er flow, it establishes a new optimization model of the studied groundwater syst em. Two optimal schemes were obtained from the model. They can be used as a refe rence to guide future groundwater development in Dalian City and to solve the si milar problems of saline intrusion along the coastal areas in the world.
