摘要
针对目前对形变的时空演变情况研究较少情况,该文以东莞市为背景,利用PS-InSAR技术获取东莞市整体形变,结合标准差椭圆分析了东莞市形变的时空演变特征。结果表明东莞市形变标准差椭圆随时间向东南方向偏移,标准差椭圆的重心由东经113.88。北纬22.93。迁移到东经113.99。北纬22.85。,长轴从51470.97m减小到48868.99m,然后增长到52985.47m后期趋于稳定状态。东莞市整体形变往东南方向偏移。
In view of the lack of research on the temporal and spatial evolution of deformation at present, Taking Dongguan as the background, this paper uses PS-In SAR technology to obtain the overall deformation of Dongguan, and analyzes the temporal and spatial evolution characteristics of deformation in Dongguan combined with standard deviation ellipse. The results show that the deformation standard deviation ellipse in Dongguan shifts to the southeast with time, and the center of gravity of the standard deviation ellipse changes from113.88 east longitude. 22.93 n. To 113.99 east longitude. 22.85 n., The long axis decreases from 51470.97m to 48868.99m, then increases to 52985.47m, and tends to be stable in the later stage. The overall deformation of Dongguan City shifts to the southeast.
