Driving forces analysis of groundwater environment evolution in the south edge of Junggar basin

Groundwater environment evolution is the comprehensive reflection to groundwater system evolution. Many studies on groundwater function can be conducted. On one hand, groundwater cycle condition is basic, emphasizes on groundwater resources property; on the other hands, groundwater environment evolution is the actual demonstration on ecology and environment properties of groundwater. This paper, bases on the changes of groundwater cycle condition, analyzing evolution process of groundwater environment, which includes spatial and temporal evolution characteristic of groundwater dynamic field and chemical field. And also bases on groundwater level, groundwater quantity and groundwater quality as environment elements, revealing the impact of natural and anthropogenic driving forces on groundwater environment evolution. In essence, natural factors, including precipitation, air temperature and surface runoff, is driving inner forces to control the direction of groundwater environment. However, anthropogenic factor, such as groundwater abstracting, division water and trench utilization and soon on, is driving outer forces to accelerate the speed of groundwater environment. The research result is not only a key to direct groundwater resources reasonable exploitation and eco-environment protection, also a typical region of groundwater sustainable utilization to the similar northwest districts.
