[Objective] To make an empirical analysis and estimate on dynamic coupling evolution in Shijiazhuang City using the data from 2005 to 2011

in order to explore the coupling interaction relationship and the development trend of coupling coordination degree between the two systems.[Methods] Guided by the concept of "smart growth"

a comprehensive evaluation index was established and a coupling coordination degree model was built by introducing the concept of coupling in physics.[Results] The two systems generally presented a synchronized development tendency and an obvious positive correlation. It can proved that there was a good coupling interaction between low-carbon economy development and urban intensive land-use. The coupling coordination level developed from serious imbalance in 2005 to good coordination in 2011. It presented that the level transited from junior to senior and the coupling interaction effect enhanced gradually. These results objectively explained the development trend of low-carbon economy and intensive land-use in Shijiazhuang City.[Conclusion] With the advancement of time and policy implementation

the coupling coordination relationships would be gradually optimized.
