长江流域皖江沿线地下水统测分析

Statistical survey and analysis of groundwater along the Wanjiang River in the Yangtze River Basin

为查明长江流域下游皖江沿线地下水现状,对长江流域下游皖江沿线地下水水位进行统测。通过调查分析气象资料、水文地质条件,选择丰水期在统测工作区域布设390个地下水水位调查点进行统测,对统测结果进行评价,结合结果总结地下水埋深、开采现状与地下水水位的相互影响。分析认为:长江流域皖江沿线地下水水位小幅上升,可满足生活、生产和生态用水需求,但部分区域由于用水过大,有形成漏斗趋势,需加强日常监测,合理开发利用地下水。分析结论以期为保护与科学开发利用地下水资源提供依据。

In order to find out the current situation of groundwater along the Wanjiang River in the lower reaches of the Yangtze River,the groundwater level along the Wanjiang River in the lower reaches of the Yangtze River was surveyed.Through investigation and analysis of meteorological data and hydrogeological conditions,390 groundwater level survey points were set up in the unified survey work area during the wet season,and the results of the survey were evaluated.Combined with the results,the interaction between groundwater depth,exploitation status and groundwater level which is summarized.The analysis shows that the groundwater level along the Wanjiang River in the Yangtze River Basin has risen slightly,which can meet the needs of living,production and ecological water.However,due to excessive water use in some areas,there is a tendency to form a funnel.It is necessary to strengthen daily monitoring and rationally develop and utilize groundwater.The analysis conclusion is expected to provide a basis for the protection and scientific development and utilization of groundwater resources.
