摘　　要：为了衡量城市边缘区土地利用效益,揭示土地利用问题,优化配置土地资源,以北京市大兴区为例,从经济效益、社会效益、生态效益3个角度构建城市边缘区土地利用效益评价指标体系,利用协调度模型,定量评价土地利用效益,动态分析土地利用效益变化情况。结果表明,当前大兴区土地利用效益协调度较高,整体呈上升趋势,其中土地利用经济效益增长最快,其次是社会效益和生态效益。由于土地利用效益受社会、经济、生态环境等多重因素影响,必须通过政策引导,实施内部挖潜,集约用地促使土地利用效益进一步提升,实现土地资源高效、可持续利用。采用功效系数和协调度模型,能有效揭示城市边缘区土地利用效益整体情况及变化趋势,有利于土地资源集约利用。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.
