CORELATIVITY ANALYSIS OF AFFECT FACTORS IN EVOLUTION HYDRODYNAMIC ENVIRONMENT IN HEBEI PLAIN

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.
