地下水动态是指地下水的水位、水量、水温和化学成分等要素随时间而变化的过程。地下水位动态常有季节性和多年的周期性变化。地下水位受自然因素(气候、地质和水文地质条件等)和人为因素(开采地下水、回灌等)的影响,不同类型的地下水,由于影响因素的差异,其水位动态类型也不尽相同。笔者在负责昌平区地下水水位长期监测工作中,应用文字说明法、统计表法、水位动态变化历时曲线法、地下水储存量变化柱状图法、地下水位等值线法和剖面图法进行地下水水位动态资料的分析研究,取得了较为理想的效果,现简要介绍如下。
Groundwater dynamic refers to the groundwater level, water, water temperature and chemical composition and other factors change over time. Groundwater level dynamics are often seasonal and many years of cyclical changes. Groundwater table is affected by natural factors (climate, geology and hydrogeological conditions, etc.) and human factors (exploitation of groundwater, recharge, etc.). Different types of groundwater have different types of groundwater due to different influencing factors. In charge of the long-term monitoring of groundwater level in Changping District, the author applied the textual description method, statistical table method, the dynamic change of water level diachronic curve method, the change of groundwater storage histogram method, the groundwater level contour method and the profile method to carry out the groundwater level dynamic Data analysis and research, and achieved a more satisfactory results, are briefly described below.
