Abstract: In order to provide decision making basis for the sustainable use of land resources, we established evaluation system based on efficiency of land use and coordinated degree. Entropy value method was used to carry out the comprehensive evaluation on the sustainable utilization of land resources in Yumen City from 2002 to 2012. The results indicated that: (1) integrated benefits of land use increased from 55.74 in 2002 to 88.89 in 2012, representing an overall increase trend year by year, and the status of land use changed from starting to the basic stage of sustainable utilization; (2) coordination degree of land use benefit decreased from 0.68 to 0.20, changing from relatively coordinated stage to uncoordinated stage. It was concluded that the overall status of land use turned to be good during the study period, but the one-sided pursuit of economic benefit in the process of social and economic development damaged the ecological and social benefits of land use. Simply pursuit of economic development without taking ecological benefits into consideration in land use was more and more obvious in Yumen City.
