[Objective] In order to provide theoretical reference and technical methods for the implementation of the next round of overall land use planning and the carrying out of the land resources management, we aimed to accurately identify and detect the potential conflicts between land use control zones and urban expansion.[Methods] Based on the CA-Markov model, the land use status of Changzhou City, Jiangsu Province in 2020 was simulated. Then, the spatial analysis technology of GIS was applied to identify and detect the potential conflict areas between the spatial regulation zone of construction lands and the development trends of Changzhou City from 2015 to 2020.[Results] ① The total scale of construction land and the amount of newly increased construction land will reach 101.16% and 159.97% respectively, which will exceed the goal of the overall land use planning by 2020; ② Little potential conflicts between construction land and the prohibiting construction zone was detected during 2015-2020; there is more areas of potential conflict between construction land and the limiting construction zone compared with the prohibiting construction zone, and about 59.15% of the potential conflict areas are mainly distributed in Wujin District.[Conclusion] The goveronment of Changzhou City should strengthen the control and management of the potential conflict areas in the limiting construction zone during the next round of land use planning.
