| 摘 要： | 以长春城区为例,分析了城市地下水赋存环境的演变,概化出该区的水文地质概念模型。将土地利用类型和供水管道渗漏对地下水补给的影响纳入城市地下水数值模拟中,经过模型识别,实测水位与计算水位的绝对误差<0.5 m,井点数占观测井总数的85%,经检验满足国家标准(GB/T14497-93)要求。结果表明,模型细化后,水位拟合精度有所提高。 |

| Abstract: | Analyzing the evolution of urban groundwater storage environment in Changchun City,the authors generalized the hydrogeological conceptual model.The urban land use types and pipeline seepage for influence on groundwater recharge were taken into account in the model.After model calibration and verification,the absolute error is less than 0.5 m between the measured and calculated water tables. The examined wells are 85% of the observation wells in total number.The goodness of fit meets the national standard(GB/T14497-93).The results show that the water table fitting precision was improved after fined model. |
| Keywords: | pipeline seepage groundwater recharge storage environment numerical simulation Changchun City |
