摘　　要：明晰低碳理念下土地集约利用水平状况不但符合低碳经济发展要求,而且对实现土地资源集约可持续利用及社会健康发展具有重要的现实意义。以我国30个省市为例,运用多因素综合评价法和HR协调度模型剖析了2007,2011,2014和2017年4个研究时点我国低碳理念下土地集约利用水平和系统协调度的时空异质性特征,并运用障碍度模型探讨了影响土地集约利用的主要障碍因子。研究结果表明:(1)研究期内各省市低碳理念下土地集约利用水平在时间和空间上均存在一定异质性,总体上随时间变化大致处于上升态势,空间上呈现由东南沿海向西北内陆逐级递减趋势;(2)各省市低碳理念下土地集约利用系统协调度普遍偏低,且与土地集约利用水平之间呈显著正相关关系;(3)影响各省市低碳理念下土地集约利用的主要障碍因子差异显著,其中土地利用碳结构系数、地均财政收入为首要障碍因子。Clarifying the level of land intensive use under the low-carbon concept not only conforms to the requirement of the low-carbon economic development but also has important practical significance to realize the intensive and sustainable use of land resources and the healthy development of society.Taking 30 provinces and cities in China as examples,in this work,the spatiotemporal heterogeneity characteristics of land intensive use level under the low-carbon concept and system coordination degree in China of four research time points in 2007,2011,2014 and 2017 were analyzed by using the multi-factor comprehensive evaluation method and HR coordination degree model.The obstacle degree model was applied to discuss the main obstacle factors affecting the land intensive use under the low carbon concept.Our research results show that:(1)In the study period,the level of land intensive use under the low-carbon concept of all provinces and cities has certain heterogeneity in time and space,and generally speaking,the trend with time change is on the rise,and the spatial trend is gradually decreasing from the southeast coast to the northwest inland.(2)Under the low-carbon concept,the coordination degree of the land intensive use system in all provinces and cities is generally low,and is strongly and positively correlated with the level of land intensive use.(3)There are significant differences in the main obstacle factors affecting the land intensive use under the low-carbon concept in various provinces and cities,among which the carbon structure coefficient of land use and the revenue per capita of land are the primary obstacle factors.
