随着城市对地下水的大量开发利用,人们对地下水位的变化规律,特别是它在将来时刻的变化趋势,常需及时或提前知道,以利于防止地下水资源枯竭,水质恶化,地面沉降等不利的水文地质工程问题,为合理开发利用和调节控制地下水,为最大限度的兴利除害提供主要科学依据。本文即利用北京城西郊所积累的二十余年地下潜水位历史资料,应用趋势分析和周期分析方法,对水位的多年变化规律及其演变趋
With the extensive development and utilization of groundwater in cities, people often have to know the law of the groundwater level change, especially its trend in the future, in time or in advance to prevent unfavorable groundwater depletion, water quality deterioration and land subsidence Hydrogeological engineering problems, in order to rational development and utilization and regulation and control of groundwater, provide the main scientific basis for the maximization of Xinglihuzhu. In this paper, we use the historical data of more than 20 years of underground submerged water accumulated in the western suburbs of Beijing City. By applying the trend analysis and periodic analysis methods, we study the multi-year variation law and evolution trend of water level
