摘要：

探究城市土地与碳排放的时空耦合关系,是协调城市土地与生态环境亟待解决的重要问题。基于重心模型、总体耦合态势模型和空间耦合协调模型,使用建成区面积、能源消费和DMSP/OLS夜间灯光等数据,分析了1995—2013年长三角地区城市土地与能源消费碳排放的时空耦合特征,并考虑空间因素的影响,构建空间滞后面板Tobit模型分析其驱动因素。结果表明：① 1995—2013年,建成区面积与碳排放量总体上均呈增加趋势。建成区面积由1251 km 2,增加至4394 km 2,碳排放量由30389.49万t,增加至90405.22万t。城市土地与碳排放间呈显著的正相关;② 城市土地与碳排放空间差异明显,上海、南京、杭州、苏州和无锡的城市建成区面积相对较大,碳排放相对较高;③ 长三角地区城市土地与碳排放耦合关系总体上呈减弱-增强-波动的态势。协调关系处于不断演化过程中,低协调阶段的城市数量明显减小,高协调阶段的城市数量明显增加,且呈集聚分布特点。南京、无锡、苏州、杭州和宁波处于高协调阶段;④ 空间滞后面板Tobit模型结果表明：城镇化对城市土地与碳排放耦合协调度具有驱动和制动的双重作用。同时,人口密度、经济水平、产业结构和空间因素对其也具有重要影响。

Abstract:

Exploring the spatio-temporal coupling relationship between urban land and carbon emissions is an important issue to be solved urgently to coordinate urban land and ecological environment. Based on data such as built-up area, energy consumption, and DMSP/OLS night lights, the spatio-temporal coupling relationship between urban land and carbon emissions from energy consumption of the Yangtze River Delta region during 1995-2013 was analyzed by the gravity center model, overall coupled situation model, and spatial coupling coordination model. By taking into account the influence of spatial factors, spatial lag panel Tobit model was constructed to analyze its driving factors. The results are shown as follows: (1)During the period of 1995-2013, built-up area and carbon emissions from energy consumption generally increased. The built-up area increased from 1251 km 2 to 4394 km 2. Carbon emissions from energy consumption increased from 303.89 million tons to 904.05 million tons. There was significantly positive correlation between built-up area and carbon emissions. (2) There was obvious spatial disparity for urban land and carbon emissions from energy consumption. There were larger built-up areas and higher carbon emissions from energy consumption in Shanghai, Nanjing, Hangzhou, Suzhou and Wuxi. (3) The coupling relationship between urban land and carbon emissions of the Yangtze River Delta generally showed a pattern of first weakened
