Abstract: Changing weather and unreasonable exploitation and utilization of water resource are not only altering the nature states,but also the supplying-flow-drainage rhythm of the native surface water and groundwater.Water becomes a fastest changing factor in the environmental elements.the loss of water makes the environments brittle greatly and comes into being many kinds of geological environmental problems as follows: desert land、salty soil、regional groundwater lever falling down and groundwater pollution.How to make use of ground-water and protect the environment in reason are pretty important.The paper emphatically concludes the geological environment problems in the west of liaohe plain,primarily studies exploitation and utilization of underwater and tables a proposal about it.
