辅助专业人员进行地下水位动态预测,为政府进行地下水资源开发利用和监督管理服务。基于GIS技术,从空间数据库提取水位相关数据系列,利用多元线性回归和逐步回归分析方法,建立地下水位与降水量、开采量、蒸发量之间的回归模型进行数据分析和水位预测,采用克里格插值方法生成水位等值线,实现预测结果的可视化表达。预测评价数据来源于空间数据库,预测结果又以空间数据的形式保存到空间数据库中去,便于进一步利用。模型将地下水位动态相关预测方法与GIS结合起来形成应用型GIS专业模型,可用于单井点或区域地下水位动态预测评价。
Assist professionals in the dynamic prediction of groundwater level, for the government to develop and utilize groundwater resources and supervision and management services. Based on the GIS technology, a series of water level data was extracted from the spatial database. Based on multiple linear regression and stepwise regression analysis, a regression model was established between the groundwater level and precipitation, extraction and evaporation for data analysis and water level prediction. The grid interpolation method generates the contour of water level and realizes the visual expression of the prediction result. The prediction and evaluation data come from the spatial database, and the prediction results are stored in the spatial database in the form of spatial data for further utilization. The model combines the dynamic correlation forecasting method of groundwater level with GIS to form an applied GIS professional model, which can be used for the dynamic prediction and evaluation of single well point or regional groundwater level.
