贵阳市地下水位监测网优化分析
|
摘要
贵阳市现有地下水位监测网存在空间布局不合理等问题,限制了地下水工作的进一步研究,为了更加合理的掌握地下水时、空分布信息,需要对现有地下水监测网进行优化。本文基于MapGIS技术,采用地下水动态分区图绘制方法,对贵阳市现有的地下水位监测井进行优化设计,并运用Kriging插值法对优化前后监测网分布合理性进行比较分析。研究结果显示,优化后研究区增设监测井28口,删除已有不合理监测井1口,监测井总数达到56口,优化后地下水位监测网标准差明显小于优化前地下水位监测网标准差,说明此优化方案较合理符合优化的目标。
The problem of unreasonable spatial layout occurs in the existing groundwater level monitoring network in Guiyang,which limits the further study of the groundwater. To understand better the time and spacial distribution of ground water,the existing groundwater monitoring networks should be optimized. Based on MapGIS technology,this paper proposes a map drawing method for groundwater dynamic partition to optimize the existing groundwater level monitoring wells in Guiyang. Meanwhile,the Kriging interpolation method was employed to conduct a comparison analysis on the optimality of the monitoring network distribution before and after optimization. The results show that after optimization,28 monitoring wells are added in the study area,one unnecessary monitoring well is deleted,which brings the total number of monitoring wells to 56. Also,the standard deviation of the groundwater level monitoring network after optimization is significantly smaller than that before optimization.Therefore,this optimization scheme proves to be effective in achieving the objective.
