天津滨海新区地面沉降速率空间插值方法对比研究
he comparative study on Tianjin Binhai New District ground subsidence velocity interpolation methods
根据天津滨海新区离散沉降速率数据通过空间内插方法获取该区域的精确插值结果,对于全面认识该区的沉降情况具有一定意义。本文借助GIS平台,利用滨海新区2011-2012年沉降速率数据,分别使用反距离加权法、全局多项式内插法、局部多项式内插法、径向基函数法以及普通克里金法得到相应的空间插值结果。在视觉分析插值效果的基础上,通过交叉验证,最终得出普通克里金法更为适合滨海新区沉降速率空间插值的结论。
In this paper we mention how imporatent to comprehensively comprehend the situation of ground subsidence in Binhai New District in Tianjin through getting precise interpolation result by several interpolation methods on discrete settlement rate data of this district. And using settlement rate data from 2011 to 2012 of Binhai New District in Tianjin, the relative interpolation results were got separately from Inverse Distance Weighting(IDW), Global Polynomial Interpolation, Local polynomial Interpolation, Radial Basis Functions and Ordinary Kriging with the help of GIS platform. Based on the analysis of visual effect and cross validation, it was concluded that ordinary kriging was better than the other methods on interpolating the subsidence rate data of Binhai Binhai New District .
