连云港市地下水压采效果评估分析

Evaluation and analysis of groundwater pressure production effect in Lianyungang

地下水资源是水资源管理是一项重要内容,同时也是维系生态系统的重要要素,是自然生态系统及环境的重要组成部分。随着社会的高速发展,人们的生活水平得到大幅度提高,生活生产方面的用水量也与日俱增。连云港市部分地区地下水水位逐年下降,已经形成中型孔隙水超采区,通过制定地下水压采方案,明确总体目标、地下水量和水位控制目标,结合替代水源,从需要与可能出发,多措并举,全面进行压采。通过对2013-2020年地下水水位埋深变化分析,结果表明一般超采区和严重超采区地下水水位埋深从2017年开始快速回升,严重超采区水位埋深速率更大,地下水压采效果显著。

Groundwater resources is an important part of water resources management, and also an important element to maintain the ecosystem. It is an important part of the natural ecosystem and environment. With the rapid development of society, people’s living standards have been greatly improved, the production of water consumption is increasing day by day. The groundwater level in some parts of Lianyungang has been decreasing year by year, and medium-sized excess pore water areas have been formed, through the establishment of the groundwater pressure mining plan, the general target, the groundwater quantity and the water level control target are defined, combined with the alternative water source, from the need and the possibility, the multi-measures are taken simultaneously, the comprehensive pressure mining is carried out. Based on the analysis of groundwater table change from 2013 to 2020. The results show that the groundwater table in general overdraft area and serious overdraft area is rising rapidly from 2017, and the water table in serious overdraft area is faster than that in other areas. The effect of groundwater pressure extraction is remarkable.
