滨海平原咸水入侵动态监测网构建研究——以潍河下游地区为例

作为进行咸水入侵动态监测的基础性工作，对潍河下游地区的供需水平衡及地下水位、水质和地层电阻率在咸淡水界面上变化规律进行了研究分析；同时，探索了监测工作的地理工程技术途径，并据此构建了3个层次的监测体系：（1）宏观区域供需水平衡分析与地下水位负值区变化监测，（2）中观咸水入侵发展变化的物探监测，（3）微观地下水位、水质变化监测；最后，为了对日益增多的咸水入侵动态数据资料进行有效的管理，设计了一个基于GIS的、以数据库管理应用为核心的信息系统。

Study on constitution of dynamic monitoring network for saltwater intrusion into seashore plain:taking the lower reaches of the Weihe River as an example

With the socioeconomic development and irrational exploitation of water resources, saltwater intrusion arose in the lower reaches of the Weihe River. Saltwater intrusion has drastically restricted the regional sustainable development. This paper probes into the scientific monitoring method of saltwater intrusion regime and the layout of monitoring network, and three kinds of monitoring network are constructed: (1) the monitoring network of the water resources supplies and demands; (2) the monitoring network of groundwater table and quality regime; (3) the monitoring network of geophysical methods. In order to make a systematic management and analysis on a large majority of data of saltwater intrusion, and apply them to solving the problem of saltwater intrusion, the paper attempts to construct a saltwater intrusion monitoring system centered about database. The system runs accurately and scientifically in practice and achieves good results.
