Abstract The affection of groundwater depression to local environment has heen unnecessarily overemphasized and exaggerated.Groundwater depression is a natural phenomena while groundwater is pumped out.By analyzing and comparing several groundwater depressions in Northeast and North China,it can be found that regional hydrogeological condition and pumping intensity affect their forming and developing.The groundwater depressions can be controlled and restored as well.It may be developed to geo-disaster only when it is out of control.The correct understanding to the characteristics and changes of depressions will be helpful to the exploration for groundwater resource and avoidance of geo-environmental problems.
