摘　　要：从社会效益、经济效益、生态效益和环境效益四方面,构建土地利用效益评价体系,采用变异系数TOPSIS法和耦合协调度模型,对武汉城市圈土地利用效益和耦合协调度进行实证分析。结果显示:(1)武汉城市圈土地利用效益具有两级分化明显区域差异悬殊的特征。社会经济效益以其他城市的低级效益为主,武汉的优良效益为辅,生态环境效益以其他城市的良好效益为主,鄂州的低级效益为辅,而综合效益则以其他城市的中度效益为主,鄂州的低级效益和武汉的优良效益为辅;(2)武汉城市圈土地利用效益耦合度均处于拮抗阶段,且区域差异较小;(3)武汉城市圈土地利用效益耦合协调度区域差异较显著,包括中度协调耦合和高度协调耦合两种类型。武汉处于高度协调耦合阶段,其他城市处于中度协调耦合阶段。Wuhan Metropolitan Area was taken as a case study in this paper.The paper established evaluation indicators for land use benefits from the aspects of society,economy,ecology and environment,and analyzed land use benefits,coupling degree and coupling coordinative degree of land use benefits by using the variance coefficient-TOPSIS method and coupling coordination theoretical models.The results showed that：（1）the land use benefits had the characteristics of obviously polarized pattern and gap of regional differences.The low-level socio-economic benefits of land use with other cities was the main,and the excellent socio-economic benefits of land use with Wuhan was complementary;the good eco-environment benefits of land use with other cities was the main,and the low-level eco-environment benefits of land use benefit with Ezhou was complementary;the moderate comprehensive benefits of land use with rest of the city was the main,then the low-level comprehensive benefits of land use with Ezhou and good comprehensive benefits with Wuhan were complementary;（2）the coupling degrees of land use efficiency was in an antagonism development stage with smaller regional differences;（3）the coupling coordination degree of land use efficiency has obvious regional differences,with moderate coordination coupling level and high coordination coupling level,Wuhan was in a high coordination coupling phase,other cities were in a moderate coordination coupling phase.
