Groundwater level prediction is also a very important field in groundwater environment prediction . land subsidence , encroachment of sea water and deterioration of water quality and so on by artificial development have relation to sustained drop of groundwater level . after groundwater level change mechanism was analyzed , the establishment method of groundwater level prediction regression analysis model was explored . and the groundwater level development trend of some planning region with the model was predicted according to its change characters of groundwater level , wath ' s more , the prediction results was analyzed
地下水位的预测也是地下水环境预测的重要内容，地下水在开采过程中所产生的地面沉陷、海水入侵、水质恶化等现象均与地下水位持续下降有关，本文在对地下水位变化机理分析的基础上，探讨了地下水水位预测回归分析模型的建立方法，并针对某规划区地下水位变化的特点，应用该模型对该规划区地下水位发展趋势进行了预测，并对预测结果进行了分析。
