Low carbon intensive use of urban land is an important trend to achieve regional high quality *** this study,with Kaifeng municipal district as an example,the catastrophe progression model was used to estimate and analyze the low-carbon intensive use level of urban land in Kaifeng City from 2011 to 2020,and the obstacle factors in the process of low-carbon intensive land use in Kaifeng City were revealed by using the obstacle degree *** results showed that during the study period,the low-carbon intensive use of land in Kaifeng City showed a slow,fluctuating and declining trend,and the overall situation was in a generally intensive *** land input level and land output level were on the rise,while the low-carbon level of land and the degree of land use were on the ***,the main obstacle factors restricting the low-carbon intensive use of land in Kaifeng City were the carbon structure coefficient of land use,energy consumption per square kilometer,carbon emissions per square kilometer,carbon emissions per capita,and non-agricultural land use *** the future,it is necessary to further improve the land use structure and promote the high-quality development of Kaifeng City.

本文基于“十一五”规划初期、“十二五”规划初期和“十三五”规划初期经济数据的样本对京津冀与长三角地区发展质量进行评价与比较。结果表明，京津冀区域整体发展水平有了实质性提升，经济社会发展协同性在不断增强，以经济增长为核心的发展逐步让位于经济、社会和生态更加均衡的发展。但京津冀区域发展能力不协调、不平衡现象仍然严峻，社会发展质量、基础设施建设和基本公共服务水平与长三角地区仍存在较大差距。基于此，提出实现京津冀区域高质量发展的政策建议，为推动区域发展质量提升提供支撑。
