摘　　要：[目的]揭示京津冀地区城市土地集约利用状况,为生态健康与低碳发展视域下的城市土地集约利用提供理论基础。[方法]相对熵组合赋权法、多因素综合评价法、协调度测算法和障碍因子诊断法。[结果](1)京津冀地区城市土地集约利用水平呈现出以京津为核心的"十字形"扩散态势。(2)系统协调度与土地集约利用水平之间显著相关,但不同城市间存在相对差异。(3)高度集约区的北京市和天津市,主要障碍因子集中在与生态健康和低碳环保有关的指标上;中度集约区的秦皇岛市和唐山市,主要障碍因子集中在与土地利用程度和布局相关的指标上,石家庄、邯郸和保定地区则集中在与生态健康相关的指标上;低度集约区的沧州、廊坊和邢台地区的主要障碍因子集中在与生态环境和低碳投入相关的指标上,承德和衡水地区集中在与经济发展和土地投入相关的指标上;粗放利用区的张家口,主要障碍因子集中在与经济发展和生态保护相关的指标上。[结论]将生态健康与低碳发展理念纳入城市土地集约利用研究中,可以较为科学全面地刻画出城市土地集约利用状况,为今后城市土地的科学利用提供决策支持。[Objective] Revealing the urban land intensive utilization in Beijing-Tianjin-Hebei area, to provide basis for the study of urban land intensive utilization under the perspective of ecological health and low-carbon development. [Methods] The relative entropy method of combination weighting, multi-factor comprehensive evaluation method, coordinate measuring method and obstacle factor diagnosis method were used in this study. [Results] （1） The urban land intensive utilization of Beijing-Tianjin-Hebei region showed a ＂cross＂ diffusion situation with Beijing City and Tianjin City as its core. （2） Correlation between coordination of the system and the intensive use of land was found significant and different regionally. （3） The main obstacle factors focused on the ecological health and low carbon-related indicators in Beijing and Tianjin cities, and focused on the land use structure-related indicators in Qinhuangdao and Tangshan cities. It is focused on the ecological health-related indicators in Shijiazhuang, Handan and Baoding cities, and in the low-carbon and ecological environment-related obstacle indicators in Cangzhou, Langfang and Xingtai cities. It is focused on the obstacle factors of economic development and investment in Chengde and Hengshui cities, and factors focused on the economic development and ecological protection in Zhangjiakou City. [Conclusion] Taking the concept of ecological health and low-carbon development into the study could provide us more scientific and comprehensive view to reflect the urban land intensive use, and provide support for the scientific land use in the future.
