Analysis of Groundwater Dynamic During the Period of 2006-2010 in Shanxi Province Basins

Based on the current status of water shortage and the serious over exploitation of groundwater in Shanxi Province,this paper analyzed the factors that influencing groundwater changes. Adopting the data of groundwater depth /level of 222 observed wells which distributed in 5 basins from2006 to 2010,this paper checked the groundwater variation after the second evaluation of groundwater resources of Shanxi Province,especially the changes of groundwater depth,the location of groundwater level decrease and the changes of flow direction. The results show that the groundwater level is declined and the buried depth is increased overall from 2006 to 2010 in the basins,while a few of overdraft areas are improved; the seasonal groundwater depths are great different and are not consistent in different basins; there are 85%,71% and 90% of monitoring wells where groundwater buried depth increases in Datong,Linfen and Changzhi basins respectively,while there exists drastic changes of groundwater buried depth in Taiyuan basin; the groundwater flow has not been changed thoroughly in the basins.
