Abstract :
Road construction profoundly affects forest landscapes, but its impact on the coupling between forest resilience and fragmentation remains underexplored. Thus, we calculated kernel density estimation (KDE) as an indicator of road density and quantified spatiotemporal dynamics of forest resilience and fragmentation in China from 2010 to 2020. We further examined how road density influences the coupling between forest resilience and fragmentation. Results showed that: (1) Forest resilience increased nationally, and fragmentation declined in most regions. (2) Bivariate spatial autocorrelation between coupling dynamics and KDE revealed high-high clusters in the Yangtze and Pearl River Deltas, and low-low in Daxinganling and southwestern Tibet. (3) SHapley Additive exPlanations showed that high KDE contributed positively and low KDE contributed negatively to coupling dynamics; multiscale geographically weighted regression revealed stronger synergistic effects in the pan-south and weaker in the northeast. This study offers quantitative insights into sustainable road planning and supports ecological restoration strategies.

Abstract :
随着道路交通碳排放量的不断攀升,全球温室效应不断加剧。近年来,在工业、能源等领域,结合因素分解模型与碳排放预测模型的双模型方法已显示出其在揭示碳排放关键驱动因素和探明碳达峰路径方面的优势,但在道路交通领域的应用尚显不足。本研究利用多尺度排放清单模型获取2001年至2019年中国道路交通碳排放数据,并采用GDIM方法对影响碳排放的驱动因素(包括GDP、道路交通能源消耗量、单位能耗碳排放量、人口总量、道路交通人均碳排放量、人均GDP、单位GDP能耗和道路交通碳排放强度)进行分解。其次,设计五种逐层递进的情景,以评估不同政策组合下的减排潜力;最后,运用LEAP模型对2021—2035年中国道路交通的碳达峰情况进行情景仿真和预测。结果显示:(1)在各驱动因素中,GDP是影响交通碳排放的最主要因素,而人均GDP是抑制碳排放的关键;(2)在各情景模拟中,中经济发展强效低碳情景(SLSC)和中经济发展强化低碳情景(ELSC)展现出最佳的减排效果,预计在2024年均能实现碳达峰,其峰值碳排放量分别为1399.9Mt和1402.69Mt;在所有车型中,商用车碳排放将于2020年的744Mt增长至2035年的约800—1300Mt,相较于其他车型,其碳减排潜力巨大;(3)尽管摩托车的碳排放量在三种车型中最低,但其排放量呈上升趋势。摩托车在单独实行“摩改电”措施后无法实现碳达峰,需要未来进一步的管控措施配合其他政策同步实施才能实现碳达峰。本研究所提出的模型及方法在交通运输碳减排中具有较好的参考价值。

Abstract :
赣闽粤地区紧邻东南沿海地区,是珠三角、长三角和粤闽浙等地区的腹地.随着赣闽粤地区经济发展和城市化进程加快,交通所带来的高碳排放问题日益突出.我国“十四五”规划提出深入实施区域协调发展战略,健全区域协调发展机制.长期以来,国内外学术研究和政策关注往往集中在经济发达区域,如长三角、珠三角和京津冀地区.以上区域的经济发展模式和机制已经得到了充分的研究和验证.然而,赣闽粤地区则展示出经济发展不均衡的特征,既包含经济发达的珠三角地区(广东省),也包含相对欠发达的内陆区域(江西省),故对于赣闽粤地区的研究有助于全面理解区域经济发展的多样性和不均衡性,并为其他欠发达地区提供参考.综上,针对赣闽粤地区交通碳排放时空差异及驱动力尚不明确的挑战,引入标准差椭圆分析法探明赣闽粤地区交通碳排放的空间分布特征(2009~2021年),基于所构建的LMDI和M-R分解模型从时间和空间层面探明碳排放空间分异的驱动力.结果表明:(1)赣闽粤地区交通碳排放总量呈逐年增加趋势,其碳排放重心主要位于广东省和福建省的交界处,且持续向“东北-西南”方向转变;(2)经济发展水平和人口规模是交通碳排放的主要驱动力;而能源强度是关键的抑制因素;(3)三省碳排放与平均水平相比存在显著的空间差异.研究结论可以为制定赣闽粤地区差异化碳减排政策和联合治理措施提供重要参考.

Abstract :
在中国城市化和地区发展差异的背景下,不同城市的交通碳排放表现出时空异质性.尽管已有研究关注道路交通碳排放,但对东南沿海城市群,尤其是福建省的研究较少.选取福建省作为研究对象,基于标准差椭圆揭示福建省城市群碳排放在时间和空间上的分布特征.此外,采用时空地理加权回归模型(GTWR)和地理探测器探明城市化水平(UR)、基础设施水平(IR)、客运量(PV)、货运量(FV)以及人均GDP(APGDP)这5个驱动因素对福建省辖内城市的道路交通碳排放的交互作用和时空异质性.结果表明,福建省城市群的道路交通碳排放量在过去20 a间持续增长,年均增长率达到10.355%,且碳排放的空间分布呈现出明显的“东北-西南”走向;其次,碳排放重心在研究期内均位于福建省泉州市内,且碳排放方位角呈逆时针趋势,持续向“东北-西南”方向转变;再次,单驱动因素的时空异质性结果显示,APGDP对城市群道路交通碳排放主要起正向驱动作用;而UR、IR、PV和FV则在不同城市内起抑制或促进作用;最后,地理探测器的双驱动因素的交互作用结果显示,IR∩UR、IR∩PV、IR∩FV和IR∩APGDP交互作用对福建省城市群的道路交通碳排放时空异质性的贡献最大.研究为揭示城市群的交通碳排放差异提供了新的视角,对于推动区域交通的低碳转型具有重要意义.

Abstract :
在“双碳”目标与“美丽中国”政策的推动下,绿色发展转型已成为国家战略的核心内容.作为主要的碳排放源,交通领域的碳排放问题尤为突出.现有的交通减碳研究多聚焦于运输结构调整和能源结构调整对碳排放的影响,而涉及产业结构调整与城市绿地环境改善的研究则相对较少.以北京市作为研究对象,构建了涵盖经济、人口、能源与环境等多因素的系统动力学模型.通过设置4种减排情景——调整产业结构(AIS)、调整运输结构(ATS)、调整能源结构(AES)及提升城市绿化(IUG),对各情景及其组合的减排潜力进行了评估.结果表明,在单一情景中,AIS情景的节能减碳效果最为显著,节能率和减排率分别为6.50%和6.69%;在双组合情景中,AIS和AES组合的节能减碳效果最佳,节能率和减排率分别为11.20%和11.36%;当4种情景综合实施时,节能率和减排率分别达到15.00%和16.24%.研究揭示了产业、运输、能源结构以及绿地环境在推动交通绿色发展转型中的协同作用,可为实现交通领域的碳减排目标提供理论基础.

Abstract :
Forest ecosystems are essential for mitigating global environmental change. However, the impact of the rapid global urbanization process on forest carbon sequestration remains unclear. Hence, we calculated the foresturban carbon balance index (CBI) from 1985 to 2020 at multiple scales (continental, national, and climatic). We applied eXtreme Gradient Boosting (XGBoost) combined with SHapley Additive exPlanations (SHAP) to identify key driving factors across regions and used multiscale geographically weighted regression (MGWR) to uncover spatial inequalities in their effects on carbon balance. Results revealed that: (1) CBI increased from 0.77 to 3.02 g C/m2/y- 1 during 1985-2020, while forest carbon flux decreased from -3.55 to -7.68 g C/m2/y- 1. Urbanization carbon loss was 1.90 times that of forest carbon loss, with high values concentrated in eastern China and northern India. (2) CBI hotspots were identified in the Amazon, the Congo Basin, and Southeast Asia, while cold spots were found in the boreal forests of Canada and Russia. (3) XGBoost-SHAP analysis revealed that temperature and precipitation were key influences in regions such as the Amazon and Sub-Saharan Africa, whereas population density was a dominant factor in the southwestern United States and eastern Australia. (4) MGWR analysis identified slope, temperature, precipitation, road density, and human footprint as synergistic drivers, while elevation, accessibility to cities, and GDP had trade-off effects. These drivers displayed spatial heterogeneity, with varying bandwidth impacts. Our findings enhance understanding of global forest-urban carbon dynamics and highlight regional development inequalities, supporting efforts in reforestation and urban planning for sustainable carbon management.

Abstract :
This study addresses the gap in understanding carbon emissions from transportation across intraprovincial cities in Fujian Province, China's first ecological civilization pilot province. This research employs a top-down approach to estimate transportation carbon emissions in Fujian Province, complemented by Standard Deviation Ellipse (SDE) and Logarithmic Mean Divisia Index (LMDI) methods to analyze spatiotemporal variations and driving factors of emissions. We also incorporate a Multi-Region (M-R) decomposition model to assess the impact of economic, demographic, and land-use factors on emissions. The results reveal significant disparities among prefecture-level cities. The economic factor, land use structure, and population growth were identified as the main drivers of transportation carbon emissions, while land use output showed a significant mitigating effect, highlighting the role of improving land-use efficiency in reducing emissions. Coastal cities showed stronger emission-driving effects compared to inland areas. The findings offer targeted insights for low-carbon transportation planning and differentiated policymaking among cities.

Abstract :
Achieving carbon peak in the transportation sector is critical for mitigating climate change and promoting sustainable urban development. This study focuses on the Urban Agglomeration on the West Coast of the China Strait (UAWCC), a major economic region with high transportation demand and significant energy consumption. Using the Logarithmic Mean Divisia Index (LMDI) method, we quantify the key drivers of transportation-related carbon emissions, including energy structure, energy consumption, transport intensity, economic development, and population dynamics. We further apply the Long-range Energy Alternatives Planning (LEAP) model to simulate energy consumption and emissions from 2020 to 2035 under baseline, low-carbon, and enhanced lowcarbon scenarios. The results indicate that without intervention, emissions will continue to rise, whereas under stringent low-carbon policies, emissions could peak by 2030. The analysis also incorporates methane (CH4), nitrous oxide (N2O), volatile organic compounds (VOCs), and sulfur dioxide (SO2), providing a comprehensive assessment of co-benefits for air quality. The research offers valuable insights for policymakers in advancing clean energy adoption, optimizing transport structures, and formulating targeted strategies to support China's carbon peaking goals.
