The monitoring results in recent years show that land subsidence in Zhengzhou has been developed rapidly. In order to find out the evolution law of Zhengzhou’s land subsidence and serve the prevention and control work of urban land subsidence, the authors selected the synthetic aperture Radar(SAR) data in recent years (2007—2017), compiled the land subsidence distribution maps of Zhengzhou in four periods of 2007—2010, 2012—2013, 2013—2016 and 2016—2017 by combining with the bench-mark monitoring results, and analyzed the evolution law of Zhengzhou’s land subsidence from time and space. By the GIS room analysis method, the authors studied the space-time response relation between land subsidence and urban village evolution in recent years. Research results show that the urban village is the predominant factor in the land subsidence evolution of Zhengzhou, namely, the groundwater abstraction in urban village causes land subsidence; the relocation of urban village and reduction of groundwater abstraction cause slow land subsidence and even uplift of land subsidence; the relocation causes the floating population to move to outer suburbs, which forms a new floating population and industrial accumulation area, and further forms a new ground subsidence area.
