| 摘要: |
| 为了建立更符合研究区的地下水数值模型，提升模型的计算精度，提高水资源的管理水平。采用Kriging插值和地统计分析的方法对研究区现有的地下水监测网进行优化，分析了地下水监测站网优化前后所建立地下水数值模型的计算精度。结果表明，监测站网标准差由优化前的0.2～2.7变为优化后的0.5～0.8，整体标准差显著减小；优化后的监测站网所建立的地下水数值模型的精度优于利用原有的监测站网所建立的模型，更有助于模型的后续计算。 |

| Abstract: |
| This paper investigated how to improve the accuracy of groundwater numerical modelling and the consequent water resource managements using Kriging interpolation and geostatistical analysis. We compared the simulated results with and without optimizing groundwater monitoring networks. The results showed that the standard deviation of monitoring network ranged from 0.2～2.7 to 0.5～0.8, and the overall standard deviation decreased significantly. The groundwater numerical model after optimizingthe monitoring network was superior to the original method, helping any pro-calculations after the groundwater simulations. |
