大连地下水开发模式探讨

为探讨提高大连地区水资源利用率的方法,通过分析总结大连地区滨海水文地质条件,剖析了地下含水系统的独立流域特征、开发价值特征、流动系统特征和环境水文地质的脆弱性特征。在此基础上,提出了大连水资源开发应以流域开发为指导思想、以地下水库为技术方法的加大开发地下水水资源利用模式,并进一步得出岩溶含水系统与河谷砂砾石堆积具有较大开发潜力而基岩裂隙含水系统开发难度较大的结论。

Exploitation pattern of groundwater in Dalian Area

In order to approach a way of advancing the water resources use rate in Dalian Area, this paper analyzes and sum-marizes the characteristics of the coast hydrogeology including independent watershed, developing value, flow system andthe vulnerability of environment hydrogeology. And based on these characteristics, the paper brings forward a water re-sources’ utilization mode of watershed exploitation direction and groundwater reservoir technology, and furthers the conclu-sion that karst and valley filling systems are more valuable and easier than bedrock fissure system as far as groundwater de-velopment is concerned.
