基于化学动力学理论的中深层地下水资源评价——以四平市区为例

运用化学动力学和水动力学相结合的理论和方法,提取了反映中深层地下水的赋存环境特征、循环速度、资源量组成、可更新能力等方面的重要信息,并以此为依据进行了四平市区中深层地下水资源评价和补给能力分析。研究结果表明,目前四平市区该层地下水已经处于超采状态,四平市区中深层地下水具有补给能力较弱,补给资源有限,水循环滞缓的特点,作为供水水源缺乏保障性。

The Evaluation of Middle-and Deep-layer Groundwater Resource and the Analysis of Its Recharge Capability Based on the Theory of Chemical Dynamics --A Case Study on the Urban Area of Siping City

The information of the aquifer characteristics, the velocity of groundwater cycle, the composition of groundwater resources , the renewable capability of middle- and deep-layer groundwater is acquired by the theory and method of chemical dynamics and water dynamics,which are based on hydrogeological data and phreatic water and middle-and deep-layer groundwater chemical analysis data. According to these, the evaluation of the middle-and deep-layer groundwater resource and the analysis of its recharge capability have been completed in the urban area of Siping city. The results indicated that the middle-and deep-layer groundwater has been exploited extensively at present, and it has the characteristics with the weak recharge capability,the limited recharge resource and the slow water cycle ,which has a lower assurance as the supply of water source.
