摘　　要：为消除鲁西南地面沉降发育区中层地下水位监测空白、提高鲁西南平原地区中层地下水监测网的监测精度,并预测地面沉降的发展趋势。结合诱发地面沉降灾害的因素,利用水文地质分析法、普通克里金法和聚类分析法对鲁西南中层地下水位监测井网布局进行组合优化。结果表明,优化完成后的鲁西南中层地下水位监测网克里金插值误差标准差由1.025降至0.499,监测精度显著提高;优化后的地下水位监测网不仅能全面监测鲁西南中层地下水位动态变化,还能对其地面沉降发育状况有一定的响应和预测能力,为今后鲁西南地下水位监测网优化布设提供了参考依据。In order to eliminate the gaps in the monitoring of the middle groundwater level in the ground subsidence development area of southwest Lu,improve the monitoring accuracy of the middle groundwater monitoring network in the plain area of southwest Lu,and predict the development trend of ground subsidence,this paper combines the factors inducing ground subsidence disasters,and optimizes the layout of the middle groundwater level monitoring well network in southwest Lu by using hydrogeological analysis,ordinary Kriging method and cluster analysis method.The results show that the standard deviation of Kriging interpolation error of the optimized network was reduced from 1.025 to 0.499,and the monitoring accuracy was significantly improved.The optimized regional groundwater monitoring network can not only comprehensively monitor the dynamic changes of the regional middle groundwater level,but also have certain response and prediction ability to the regional ground subsidence development,wich provides a basis for optimizing the deployment of the regional groundwater monitoring network in the future.
