%X Groundwater is one of the most important aspects of hydrological cycle in Yellow River Delta.Groundwater systems play an important role in integrating land and water management as well as in maintaining and protecting wetland.In this study,the isograms of groundwater depth show that the depth of groundwater near the Yellow River is deeper and near the sea and the interfluvial lowlands is shallower in the typical region.Based on the bivariate and partial analysis by SPSS 11.5 software,the interactions between groundwater depth and precipitation or runoff quantity are analyzed both on the annual and monthly variations of groundwater.It is revealed that:the variations of groundwater depth in Yellow River Delta(besides the nature reserves) do not have obvious rule and are controlled by multiple driver factors,which have different effects on groundwater depth at different stages or sites.In this region,the variations of groundwater are complicated and not controlled by precipitation and runoff quantity.Moreover,human activities,including the irrigated-runoff,the deposited-runoff in reservoirs from the Yellow River which provide urban domestic and industrial water quantity,may become more important influencing factors which lead to the rise of groundwater level.This study provides some basic information as requirement for the management of groundwater resource and protection of wetland in the delta.However,limited by data and length of the paper,the quantitative relationship between human activities and groundwater depth will be studied in future research.
