Based on data about underground water level,climatic variation and the amount of groundwater mining,and through the methods of wavelet transform (WT) and fuzzy matrix,factors inducing the abnormal variation of groundwater flow field in Shijiazhuang as well as the characteristics are studied,to reveal the factors driving the evolution of groundwater flow field in Shijiazhuang. The results indicate that:(1) the central level and area of groundwater depression cone decreases with the increase of P_e value (ratio of precipitation to groundwater mining),and the trend fits well to the power function,with a declining degree of P_e value in dry years 1.8 times or 1.9 times of that in wet years;(2) the central level and area of groundwater depression cone increases with R_e value (ratio of replenishment to groundwater mining),which is in a trend of decrease and showed the characteristics of power function;(3) due to the construction of water conservancy projects in the upstream, the recharged quantity through infiltration of surface water decreased 49%,and the recharged quantity through well irrigation decreased 17%. With the above method successfully applied in this research as the results basically coincide with the actual cases,this study can be served as guidance to regional groundwater development and utilization.
