基于耦合理论的中国建设用地变化与GDP增长关系研究

Analysis Relationship Between Construction Land Changes and GDP Growth in China Based on Coupling Theory

为了深入分析城市建设用地与经济发展之间的关系，研究不同地区城市建设用地与GDP增长之间的关系状态的异同，将解耦理论和解耦分析引入到建设用地变化与GDP增长之间的关系分析中。研究表明，在2003—2008年期间．各地区建设用地变化与GDP增长的解耦与耦合程度存在时空差异性的同时，也存在主导类型或主要转变趋势。（1）在2003．2008年期间，从全国尺度来看，存在从弱解耦状态转向弱耦合状态转变的态势。（2）中国各省级区域建设用地变化与GDP解耦程度差异较小，在空间上呈大部分连续的分布状态。（3）建设用地与GDP的解耦过程可能会向相反方向的发展．其过程具有曲折性。

In order to analyze the relationship between urban construction land and economic development, and to know the similarities and differences of the relationship in different province in China, decoupling theory was introduced to analysis on the relationship between construction land change and GDP growth. Research showed that, during 2003-2008, spatio-temporal difference was existed in every province in China about decoupling and coupling degree between construction land change and GDP changes. At the same time, there was also the leading type or major change trend. （1） During the 2003-2008, from the national scale, the interaction between construction change and GDP growth varied from weak decoupling state to the weak coupling condition. （2） Decoupling degree between construction change and GDP growth has a little difference in each provincial region in China, which showed majority continuous distribution in space. （3） Decoupling process between construction land and GDP growth may be turn into opposite direction, and the process was tortuous.
