摘要
以华北平原(河南部分)为研究对象,采用短基线集InSAR监测技术,基于RadarSat-2雷达图像数据,以形变监测为需求,对该区域开展地表沉降监测,并分析其成因。整体反演沉降区与城市发展形成的地下水漏斗区、地热应用密集区以及濮阳油田开采沉降区的空间分布基本吻合,进一步证明人类社会活动是形成地表沉降的重要因素。
Taking the North China Plain(Henan part)as the object,using the short baseline set InSAR monitoring technology,based on RadarSat-2 radar image data,taking the deformation monitoring as the demand,we carried out the surface subsidence monitoring in this area,and analyzed the causes.The overall inversion subsidence area is basically consistent with the spatial distribution of groundwater funnel area,geothermal application intensive area and mining subsidence area of Puyang oilfield,which further proves that human social activities are the important factors for the formation of surface subsidence.
