The establishment of Xiong’an New Area is a millennium plan and a national strategy. Located in the North China plain, the largest subsiding zone of China, the ground subsidence condition of Xiong’an New Area is an important factor related to its environmental carrying capacity. The ground subsidence of Xiong’an New Area was monitored using time-series InSAR technique with 28 RADARSAT-2 images acquired from January 2012 to November 2016. The annual subsidence rate and the accumulative subsidence series over Xiong’an New Area were retrieved. The InSAR monitoring result was validated by leveling data measured over the similar period with the SAR image acquisitions. Subsequently, driving forces of ground subsidence over Xiong’an New Area was analyzed, and the land in Xiong’an New Area was categorized into 4 subsiding risk levels according to annual subsidence rate. The results show that about 78% of Xiong’an New Area had little ground subsidence with annual subsidence rate less than 10 mm per year, and the large subsidence occurred only in Xiongxian county which was mainly caused by extraction of geothermal resources and groundwater. There were 67.9 km2 with the subsiding risk categorized as relatively serious and serious levels, accounting to 4.38% of Xiong’an New Area. The result of this research could provide decision-making reference for the construction and development of Xiong’an New Area. [ABSTRACT FROM AUTHOR]
