摘　　要：[目的]评价成渝城市群城市土地利用效率及耕地利用效率,促进成渝城市群新型城镇化与农业现代化的共同发展。[方法]基于2005—2014年统计数据,建立城市土地利用效率与耕地利用效率的指标体系,综合运用Super SBM模型、重心转移模型及耦合协调度模型,分析成渝城市群城市土地利用效率、耕地利用效率的时空格局及二者的耦合协调水平。[结果](1)2005—2014年,成渝城市群城市土地利用效率呈波动向上发展,效率重心垂直向南移动幅度较大;(2)耕地利用效率整体上呈现V形波动,效率重心在水平方向上向东转移趋势明显;(3)研究区域内城市—耕地利用效率耦合协调类型数量呈"纺锤状"结构分布,高耦合中协调度型城市数量众多,南—泸一线城市耦合协调类型变化强烈。[结论]成渝城市群城市土地—耕地利用效率耦合协调度较高,呈良性发展态势。[Objective]Evaluating urban land use efficiency and cultivated land use efficiency of ChengduChongqing urban agglomeration,to promote the common development of new urbanization and agricultural modernization.[Methods]Taking Chengdu-Chongqing urban agglomeration as a research object,the paper built up an evaluation system of urban land use efficiency and cultivated land use efficiency.Super SBM model,gravity center model and coupled coordination model were used to analyze the spatial-temporal pattern and coupling coordination degree of the two.[Results]From 2005 to 2014,urban land use efficiency followed a fluctuating ascending trend and the efficiency center of gravity shifted vertically to the south.The cultivated land use efficiency presented a V type as a whole.Gravity center changed greatly in the horizontal direction to the east.The coupling type and coordination degree with respect to the utilization efficiency of coupling coordination of urban land and cultivated land showed a shape like spindle.There was great number of highcoupling medium coordination cities in the research object.Cities along Nanchong-Luzhou changed greatly in terms of coordination type.[Conclusion]The coupling degree of urban land use efficiency of ChengduChongqing urban agglomeration is relatively high and has a positive development trend.
