[Objective] Evaluating urban land use efficiency and cultivated land use efficiency of Chengdu-Chongqing 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 high-coupling & 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 Chengdu-Chongqing urban agglomeration is relatively high and has a positive development trend.
