The impacts of climate change, groundwateroverdraft, surface runoff and food production changes on water resources are analyzed.
分析了气候变化、地下水超采、地表径流及粮食产量变化等方面对水资源的影响。

The groundwater exploitation potential of irrigation region is less than the permissible utilization volume of groundwater, groundwateroverdraft is remarkable in irrigation region.
现状年地下水开潜力很小，甚至有些灌区开采潜力严重不足，超采严重。

For many years, because of overdraft of the deep groundwater has resulted in serious geologic hazards.
