In recent years, landslide disasters in Guangxi have increased, threatening people's safety.In order to provide relevant departments with scientific landslide monitoring data to formulate a reasonable and effective prevention plan,this article takes the Cenxi area of Guangxi as an example, the surface deformation was extracted using InSAR technology and the Sentry-1A data from 2016 to 2019 in the Cenxi area. Combined with precipitation data, the main landslide hazards were evaluated and the deformation time series analysis was carried out. The results show that the landslides in Cenxi area are mainly distributed in mine goafs, highway slopes, and country mountains, and the slope settlement is mostly affected by human activities. The complex geology of Guangxi and the impact of rainfall are also the reasons for the sinking. With the industrial transfer and the rapid development of the regional economy, the settlement of mines, urban and rural roads and slopes in the region has gradually increased and expanded.
