天津市塘沽区地面沉降监测网络优化

Land Subsidence Monitoring Network Optimization at Tanggu in Tianjin

以天津市塘沽区为研究区域,利用空间聚类与数据序列特征分析相结合的方法,对原有86个监测点的地面沉降监测网络进行优化,使优化兼顾了空间均匀分布和最小化时间冗余。给出了监测点数目,仅保留其中大约25%的监测点进入优化后的监测网络。

A method combining spatial cluster with data statistical analysis was employed to optimize a land subsidence monitoring network consisted of 86 monitoring points at Tanggu in Tianjin. So the optimized network met with the goal of both maximizing spatial accuracy and minimizing temporal redundancy. Giving the number of monitoring points, an optimized network containing a selection of about 25% monitoring points from the original network was built.
