河北平原地下水动力环境演化影响因素的关联度分析
CORELATIVITY ANALYSIS OF AFFECT FACTORS IN EVOLUTION HYDRODYNAMIC ENVIRONMENT IN HEBEI PLAIN
-
摘要: 本文以河北平原典型地区-石家庄、衡水、沧州地区为例,采用灰色关联度分析方法,分析了地下水动力环境演化的影响因素。结果表明,对于第一含水组地下水,水动力环境演化主要受气象因素控制,对于第三含水组及漏斗区地下水,人为开采是最直接的影响因素。Abstract: A grey correlativity analysis method is used in analysis of the affecting factors in evolution of hydrodynamic environment in same typical areas of Hebei Plain,such as in Shijiazhuang,Hengshui and Changzhou aeas.The study shows that the change of meteorological phenomena is a governing factor for aquifer system Ⅰ,and the water expoitation is a direct affect factor affect on aquifer system Ⅲ and depression cone areas.
