济南泉域岩溶地下水动态开采模型研究

Study on Dynamic Exploitation Model of Karst Groundwater in Jinan Spring Area

通过收集近3年来济南泉域岩溶地下水开采量、降雨量、泉水流量及泉群水位资料,进行了相关性分析及回归分析。揭露了四大泉群之间内在联系及影响泉群水位变化关键变量间的相互关系,以此为基础建立了岩溶地下水年内动态开采模型。该模型量化了不同时期地下水的开采量,有利于引导当前开采模式下水资源配置,对实现泉水保护及城市供水具有重要意义。

Through collecting datas of exploitation quantity, precipitation, spring water discharge and spring water level of Jinan spring area in recent three years, correlation analysis and regression analysis have been carried out. It revealed the internal relation between four springs and relation among main varia- bles which affect the spring water level. On these basis, annual dynamic exploitation model of karst groundwater has bee set up. The model quantifies the exploitation quantity of groundwater in different pe-riod. It is beneficial to guide the allocation of groundwater resources on the current exploitation mode, and has important significance on spring protection and city water supply.
