基于SBAS-InSAR的滨州市地表沉降及其对影响因素分析

Analysis of Surface Subsidence and Its Influence on Factors in Binzhou City Based on SBAS-InSAR

基于目前研究地表沉降影响原因时多注重单个影响因子影响作用与“横向”种类间对比分析,而忽视了影响因素间的相互作用的目的,采用SBAS-InSAR技术得到滨州市2016年~2020年的平均沉降速率,并结合其他因子,使用地理探测器定量分析地表沉降影响因子及其相互作用机制,得出:①工矿用地、盐化工产业和砂土因子对地表沉降影响力度最大;②因子之间的相互作用也均显示为显著增强关系,其中采矿用地、砂土盐化工产业三因子交互作用表现最强。

Based on the current research on the causes of surface sedimentation,which mostly focuses on the comparative analysis between the influence of individual influencing factors and“horizontal”categories,but ignores the interaction between influencing factors,the SBAS-InSAR technique was used to obtain the average sedimentation rate of Binzhou City from 2016 to 2020,and combined with other factors,the geographic probe was used to quantitatively analyze the influencing factors of surface sedimentation and their interaction mechanisms.mechanism,and concluded that①the mining land,salt and chemical industry and sand and soil factors have the strongest influence on surface subsidence;②the interactions among the factors also all show a significantly enhanced relationship,with the interaction of the three factors of mining land,sand and salt and chemical industry showing the strongest performance.
