摘要：With the continuous acceleration of urbanization, the construction land around Dianchi Lake has been expanded, which may result in serious surface deformation and produce adverse environmental impacts. To explore the influence of city expansion on ground subsidence in Kunming, in this paper, we used the SBAS-InSAR technique to invert the time series deformation velocity of Kunming by sentinel-1A datasets acquired from October 2018 to October 2019. The results showed that an average subsidence velocity up to -30mm/year at the north bank of Dianchi Lake. The deformation velocities extracted from descending and ascending datasets show similar results with R-2 equaling to 0.9677. The results showed the potentiality of SBAS-InSAR technology and provides a more effective monitoring method for surface subsidence in mountain areas.
