[Objective] The relationship between low carbon economy development and land intensive utilization was studied to provide theoretical reference for the development of low carbon economy and land intensive utilization of Zhengzhou City. [Methods] Based on the data from 2002 to 2011 in Zhengzhou City, Tapio elastic analysis method was used to build the evaluation index system of decoupling. [Results] Integrated carbon consumption was strongly decoupled with land intensive utilization in 2002-2004. They were in expansive negative decoupling state in 2004-2005, in weak decoupling state from 2005 to 2010 and in strong decoupling state in 2010-2011. [Conclusion] There exists a significant positive correlation between low carbon economy and land intensive utilization, the growth of low carbon economic effectively promotes the improvement of intensive land use level.
