Abstract: In order to measure the land use efficiency of urban fringe area, reveal the problem of land use, optimize allocation of land resource, the author took Daxing District of Beijing as a study area, and established an indicator system from the aspects of social, economic and ecological benefits, then evaluated land use benefits based on the coordination-degree model and analyzed its spatial variability. The results showed that land use benefit was increasing. The economic benefits was growing fastest, which followed by social and ecological benefits. Because it affected by many factors, people should improve land use benefit by policy guiding and intensive utilization. The effect function method and the coordination degree model could effectively reveal the level and the change tendency of land use benefits in urban fringe area, and was advantageous to the optimization of land resource distribution.
