“十三五”期间淮北市孔隙水环境变化特性研究

Study on variation characteristics of pore water environment in Huaibei city during the 13th Five-Year Plan period

淮北市孔隙水分布面积大、范围广。基于淮安市41个监测站点2006-2010年地下水位、水质监测资料,对"十三五"期间淮安市孔隙水环境变化特性及成因进行研究,结果显示:"十三五"期间由于开采量增大、降水量减少导致孔隙水水位呈下降趋势,但水位总体较2001-2005年增高,地下水开采量对降落漏斗影响较大。孔隙水水质较为良好,水温度较稳定,受气候变化影响较小。开采量和降雨量的变化是导致地下水环境变化的主要原因。研究结果可为后期区域地下水保护与科学开发利用提供参考依据。

large and wide of the pore water distribution area is in Huaibei city.The variation characteristics and causes of pore water environment in Huai ’an city during the 13 th Five-Year Plan period has been studied based on the groundwater water quality monitoring data of 41 monitoring stations in Huai ’an from 2006 to 2010,The results showed:The pore water level shows a downward trend because of increasing exploitation quantity and precipitation reduction during the 13 th Five-Year Plan,but water levels were generally higher than from 2001 to 2005,thus the falling funnel has been great influenced by groundwater exploitation.Pore water quality is relatively good,the water temperature is stable,less affected by climate change Production and changes in rainfall is a major cause of lead to groundwater environmental change The research results can provide reference for the protection and scientific exploitation of regional groundwater in the later period.
