烟台地区地下水库建设的地质环境条件及其效益浅析

Study on Geological Environment Condition and Its Effects of Underground Water Reservoir Establishment in Yantai City

烟台市是环渤海经济区的重要组成部分,是山东省乃至整个北方地区重要的工业开发区,但支撑其经济社会以及生态环境发展的淡水资源匮乏,而且由于地下水资源的不合理开发诱发或加剧了地下水资源枯竭和海水入侵等地质环境问题。为此,本文通过典型案例较系统分析总结了该区地下水库建设的4 个基本条件,即理想的地表拦蓄条件、良好的地下水调蓄条件、优越的补给水源条件和适宜的自然与社会环境条件等;同时对地下水库建设带来的经济社会效益和生态效益进行了论证,并提出了尽快制定勘查与建设方案的建议,以缓解淡水资源匮乏的现状,改善地质环境。

Yantai city, as an important part of economic areas around Bohai sea, is an important industrial developing zone in Shandong province, even in the whole north part of China, while fresh water is very lack in this area. Furthermore, due to unreasonable exploitation, some geological environment problems, such as drying up of fresh water and seawater intrusion have been heightened. Thus, through typical examples, 4 basic conditions for establishing underground water reservoir in this area are analysed comprehensively, they are as follows: perfect surface water blocking and storing condition, good adjustment condition for undergroundwater, predominant water recharging source and stuitable natural and social conditions. Meanwhile, economic, social and ecological efficacies brought by establishment of underground water reservoir are proved as well in this paper. Suggestions are put forward to enact exploration and establishment plan immediately in order to allay the lack of fresh water, and to improve geological environment.
