摘要
地下水动态变化不仅影响居民生活生产用水,还可能引发一系列环境地质问题。为研究河南省新郑市浅层地下水水位变化趋势,本文收集2015年1月—2019年12月新郑市5眼观测井的监测资料,统计地下水埋深变化,分析影响其埋深的因素。结果表明:新郑市地下水位埋深较深,多数地区地下水埋深大于20 m,近5年间除观测孔3地下水埋深减少4.02 m,其他观测孔埋深均增加1~5 m。通过分析影响埋深变化的因素发现:随气温、降雨量季节周期性变化,浅层水位埋深的周期性变化并不明显;当地地下水位埋深较深,蒸发对其影响可以忽略;开采量的变化与地下水埋深变化相一致,推测地下水开采量仍是影响浅层水位埋深变化的重要因素,因此严控开采量仍是保护当地地下水资源的重要措施。
The dynamic change of groundwater not only affects the living and production water of residents,but also may cause a series of environmental geological problems.In order to study the change trend of shallow groundwater level in Xinzheng City,the monitoring data of 5 eye observation wells from January 2015 to December 2019 were collected,and the change of groundwater depth was statistically analyzed.The results show that the groundwater level in Xinzheng City is deep,and the groundwater depth in most areas is more than 20 m,During recent 5 years,the ground-water depth of observation hole 3 decreased by 4.02 m,and the groundwater depth of other observation holes in-creased by 1~5 m.By analyzing the factors affecting the change of groundwater depth,it found that with the seasonal periodic change of temperature and rainfall,the periodic change of shallow water level is not obvious.The local groundwater level is deep,and the influence of evaporation on it can be ignored.The exploitation amount is consistent with the change of groundwater depth.It is speculated that groundwater exploitation amount is still an important factor affecting the change of shallow water level.Strictly controlling the amount of exploitation is still an important measure to protect local groundwater resources.
