山东省博兴县浅层咸水入侵研究

Study on Shallow Salt Water Intrusion in Boxing County

摘要:

地下水资源是人类重要的自然资源，地下水资源的多少严重影响着当地居民的生活、生产和工农业发展。随着经济的发展，地下淡水资源逐渐减少，而咸水入侵的发生使得本来就稀缺的地下淡水变得更加紧张，严重影响了当地生态环境的良性循环和持续发展。该文以20世纪80年代咸淡水分界线为背景，通过取样分析获得博兴县浅层地下水现状年的咸水入侵锋面在利王—辛张—寨高—鲁崔一线；截至2017年的入侵面积为18.45km2；最大入侵距离为2.15km；最大入侵速率为0.06m/a。经过资料分析，目前博兴县浅层咸水入侵处于稳定状态。该研究对博兴县南部咸水入侵的现状和发展趋势更加深入，为当地的浅层地下水资源的开采和管理提供了科学依据。

Abstract:

Groundwater resource is an important natural resource. The amount of groundwater resources will seriously affect the lives of local residents, industrial and agricultural production and local development. Accompanying with the development of economy, underground water resources has been gradually reduced. The salt water intrusion makes the scarce underground fresh water become more nervous, which has influenced the virtuous circle and sustainable development of local ecological environment seriously. Regarding the recorded water line in the 80's as the background, through the sample analysis, it is regarded that salt water intrusion front of shallow groundwater in the basic year in Boxing county is Liwang—Xinzhang—Zhaigao—Lucui. The intrusion area is 18.45km2 from 80's to 2017. The largest intrusion distance is 2.15km, and the maximum intrusion rate is 0.06m/a. At present, salt water intrusion in Boxing county is in a stable state. It will provide a scientific basis for exploitation and management of local shallow groundwater resources.
