论安阳市区地下水位下降漏斗演变与地下水可持续利用规划

Evolution of Depression Cones and Planning of Sustainable Utilization for Groundwater in the Urban Areas of Anyang City

在进行地下水资源评价时,地下水的补给排泄均衡项有许多不确定因素,这大大降低了评价的精度,也影响了地下水可持续利用规划的科学性与准确性。根据不同时期实测的安阳市区地下水位数据,研究地下水位演变过程,得出地下水位下降漏斗形成的初始与现状地下水位变幅值(1965年-2005年或1980年-2005年),利用给水度μ值,可以较精确的计算这个时段的地下水超采量。安阳河冲洪积扇具有较大的含水空间,该地区已形成稳定的地下水位下降漏斗,此漏斗是建立地下水调蓄水库良好的场所。在安阳河冲洪积扇漏斗区规划实施地下水人工回灌是一条安阳市区地下水可持续利用之路。

There are many uncertainty factors in terms of groundwater recharge and discharge on evaluating groundwater resource, which greatly lowers evaluating precision of groundwater and affects accuracy of groundwater planning. The over-extraction amount of groundwater could be calculated accurately based on groundwater level data in different periods （1965-2005 year or 1980-2005 year） and μ parameter of aquifers by studying evolution of groundwater depression cones. There is great water containing space and have formed stable groundwater depression cones in proluvial fan of the Anyang River. This proluvial fan is a well site for setting-up underground reservoir. The artificial recharge in proluvial fan of the Anyang River is a road for groundwater sustainable utilization in the Anyang urban areas
