地下水动态,是指地下水的水位、水量、水质和水温等随时间的变化。开展地下水长期动态观测工作,就是为了掌握地下水动态情况,探索其变化规律;进行地下水资源评价、合理开发利用地下水,以及提出水资源保护(防止土壤盐碱化、地下水浸没)研究地下水补给等问题的重要依据。随着水利建设的迅速发展,引起地下水发生一些新变化。如有的渠灌区,河网
Groundwater dynamic, refers to the groundwater level, water, water quality and water temperature changes over time. Carrying out the long-term dynamic observation of groundwater is to grasp the dynamic state of groundwater and explore its changing rules; to evaluate the groundwater resources, to develop and utilize the groundwater reasonably, and to propose the research on the groundwater recharge due to the protection of water resources (prevent soil salinization and groundwater immersion) Important reference. With the rapid development of water conservancy construction, some new changes have taken place in groundwater. If any drainage area, river network
