| 摘 要： | 城市化是近代人类环境的大趋势，是每个国家现代化程度的体现，但城市发展快也会引发许多问题，其中较为严重的是地表形变，严重的地表形变容易演变成地质灾害。本文基于嵩明县现状，利用44景Sentinel-1A卫星影像通过SBAS-InSAR技术穿透云雨雾等恶劣天气对其进行地表形变监测，获得了该区域2019年1月至2020年8月期间的形变监测结果，并通过点线面式的分析方法分析其形变成因和规律，为嵩明县的城市化进程提供了参考意见。

| Abstract: | Urbanization is the general trend of modern human environment and the embodiment of each country's modernization degree. China has issued many policies for rural urbanization. Songming county, Yunnan province, is established as a county-level Songming city in 2018. It can be seen that Songming county develops rapidly compared with other counties. However, the rapid development of cities will also cause many problems, among which the more serious is the surface deformation, which is easy to evolve into geological disasters. Based on the current situation of Songming county, 44 sentinel-1 satellite images are used to monitor the surface deformation of Songming county through the severe weather such as cloud, rain and fog by SBAS-InSAR technology. The deformation monitoring results of the region from January 2019 to August 2020 are obtained. The causes and laws of the deformation are analyzed by point line surface analysis method, to provide reference for the urbanization process of Songming county. |
