Abstract:Based on DPSIR model,the system of cultivated land occupation and economic growth “economic development driving force-pressure of cultivated land occupation-condition of cultivated land-analysis of influencing factors for cultivated land occupation-cultivated land protection policy”was built.By using IPAT and variation comprehensive analysis method,the spatio-temporal variation of decoupling between cultivated land occupation and economic growth in Wuhan was analyzed.The result shows that firstly in municipality scale,during 2003-2012,the relationship between cultivated land occupation and economic growth was changed from expansion negative decoupling to strong decoupling; secondly,in district scale,during 2007-2012,the expansion negative decoupling area was transferred from central city to suburban areas; thirdly,policy response and influencing factors of cultivated land occupation and economic growth from different scales in Wuhan were analyzed by using relevant factor analysis method.In order to insure the sustainable development of economic growth and cultivated land conservation,government at all levels should strengthen the management in cultivated land occupation and intensive utilization.
