| 摘 要： | 随着城市化进程的不断加快,城市潜层地下水水质逐渐变差。研究以华北地区某重点城市为研究对象,基于Arc GIS平台研究分析了该市1980年、1990年、2000年和2010年4个时间点的地下水总硬度时空变异特征。研究结果显示:研究区在1980—2010年间潜水总硬度高浓度区域大幅增加,地下水水质变差趋势非常明显。老城区地下水总硬度经历了1980—1990年迅速上升和1990年后稳中有降两个阶段;拓展区潜水总硬度总体上呈现先缓后急的上升趋势。

| Abstract: | With the acceleration urbanization process，the quality of urban aquifer groundwater is gradually becoming worse．
An important metropolis in North China was selected as the study object． The sptio-temporal variability properties of total
hardness of aquifer groundwater at four time points( 1980， 1990， 2000 and 2010) were analyzed based on ArcGIS． The results
showed that during 1980—2010，the phreatic aquifer area with high concentration of total hardness increased greatly in
research area，and the worse trend of groundwater was very obvious． The old city zone went through two phases: The rapid
increase during 1980—1990 and stable status with slight decline after 1990． For the extended area of the city，the total
hardness in the phreatic aquifer generally presented sluggish early and quick later increasing trend as a whole． |
