Abstract：The Datong Basin located at the northern end of the Fenwei Basin is a serious land subsidence area. The groundwater exploitation is an important factor responsible for the land subsidence. However, the study of the correlation between the groundwater activities and the land subsidence in this area is very insufficient. In order to investigated the relationship between the groundwater and the land subsidence, the authors monitored the characteristics of Datong land subsidence deformation by using small baseline subset(SBAS) InSAR technique with Envisat ASAR images. At the same time, the corresponding spatial-temporal relations between the ground subsidence center and the groundwater funnel were studied. Two models illustrating relationships between the ground subsidence and the groundwater funnel were built. The research shows that underground water exploitation is a major factor responsible for land subsidence in Datong; nevertheless, not all the underground water exploitation can cause land subsidence. This study has a good reference value for guiding the production and control of the underground water exploitation and land subsidence.
