摘要：

The crustal activities in Dangxiong basin are frequent and a great deal of geothermal energy is converged under the surface. The geothermic resources are used through the exploitation of underground water. Over-extraction of underground fluids causes the subsidence in the geothermal fields. We present the application of small-baseline InSAR time series method to monitor the land surface subsidence and spatial-temporal evolution in Yangbajing. Our data consists of 24 ASAR images acquired from ENVISAT satellite, spanning a time interval from Oct 2006 to Aug 2010. The results show that the maximum surface subsidence rate of the geothermal region is up to 15 mm/yr whilst subsidence rate in other fields is approximately 6 mm/yr.
