济南泉域地下水环境容量研究

The Groundwater Environment Capacity in Jinan Springs Basin

分析了国内外关于水环境容量的概念,认为地下水环境容量可采用临界水位、容许开采量、纳污能力或支撑社会-经济-环境可持续发展的综合指标来表征,给出了地下水环境容量的涵义。以济南泉域为例,采用开采量-地下水位变动关系分析与Visual MODFLOW数值模拟相结合的方法,确定容许开采量26.53万m3/d作为济南泉域岩溶地下水环境容量的阀值,为保泉提供依据,最后指出了地下水环境容量研究的发展趋势。

Through an analysis of the water environment capacity at home and abroad, Considering that the groundwater environment capacity can be denoted by critical groundwater level, allowable yield, pollution receiving capacity and synthesis index of sustainable developmentof society, economy andenvironment, a concept of the groundwater environment capacity is put forward. The Ji＇nan Springs Area is used as an example to analyze the relation between the exploitation and the water table changes. At the same time, combined with the numerical simulation Visual MODFLOW methods. At the same time, some major directions for future research are put forward.
