Abstract：The dynamic variation of groundwater level is actually a reflection of the change of groundwater resources in aquifer. The fluctuation of groundwater level directly reflects the variation in amounts of consumption and recharge of groundwater. Based on the monitoring data of groundwater level, the variation characters of phreatic water in Lower Liaohe Plain from 1996 to 2005 are analyzed. It is concluded that whether phreatic water or confined water, the groundwater levels change along with precipitation in non-exploitation area and dry farmland area. Besides the contribution of precipitation, the exploitation scale and layout of groundwater in exploitation area are also significant influential factors for the variation characters of groundwater level.
