摘要
本文基于大同盆地30761418号地下水观测井1997-2021年观测数据,利用频谱分析法建立了该井的地下水预报模型,并对模型进行了显著性检验。2022年以后的预报结果表明,大同盆地该观测井附近地下水水位呈持续下降趋势,应采取相关措施来保证地下水位止降回升。
This paper is based on the observation data of No.30761418 groundwater observation well in Datong Basin from 1997 to 2021 as an example,the groundwater forecasting model of the well was established by spectrum analysis,and the significance of the model was tested.Forecast results beyond 2022 suggest that,the groundwater level near the observation well in the Datong Basin shows a continuous downward trend,relevant measures should be taken to ensure that the groundwater level stops falling and rising.
