运城市地面沉降SBAS-InSAR监测和敏感性GIS分析
Monitoring Land Subsistence Using SBAS-InSAR and GIS to Conduct Sensitivity Analysis in Yuncheng
摘要
Abstract
The city of Yuncheng,located in the Shanxi Graben basin,has suffered large-scale land subsidence and ground fissures,which have seriously constrained urban construction and sustainable economic development of the area.In this paper,the Small Baseline Subset Interferometer Synthetic Aperture Radar（SBAS-InSAR） technique is used to detect and measure ground movement in the area using eight ASAR images.The detailed deformation data obtained by this study revealed the spatial distribution and characteristics of the subsidence.Based on this,GIS was used to show the relationship between subsidence and tectonic factors such as faults and ground fissures,which were determined using previously collected geological data.As a result,the sensitivity index of the study area was determined using the BP neural network method,and the sensitivity level of land subsidence was analyzed using the dimensional analytical method.The results in this paper demonstrate a very powerful conclusion and will contribute to the prevention and mitigation of land subsidence disasters in this region.关键词
