河北平原地下水动力环境演化规律及影响因素

GROUNDWATER DYNAMIC ENVIRONMENT EVOLUTION AND ITS CONSTRAINTS IN HEBIE PLAIN

通过河北平原多年地下水位长期观测资料的整理、统计和分析，探讨了地下水动力环境演化规律，并选择典型地区，采用灰色关联度分析方法，论证了地下水位变化与开采量、降水量之间的内在联系，从而揭示了地下水动力环境演化机制。

Based on statistical analysis of long-term groundwater observation data,the evolution patterns of groundwater dynamic environment in Hebei Plain in the past are discussed.Meanwhile,taking Shijiazhuang,Hengshui and Cangzhou districts as examples and using the gray connection degree analysis method, the relationships among the change of goundwater table, exploitation and precipitation are demonstrated,thus,the mechanisms of groundwater dynamic environment evolution are explained.
