Abstract
Population urbanization significantly influences urban carbon dioxide (CO2) emissions. As urban areas expand and populations grow, the demand for energy and resources rises, contributing to higher CO2 emissions. Understanding the objective laws and mechanisms linking these factors is crucial for promoting low-carbon and environmentally sustainable urban practices. This study utilizes the Spatial Autoregressive (SAR) model to explore the impact of population urbanization on CO2 emissions and innovatively investigates the roles of policies and demographic factors in this process. By examining 30 representative provincial administrative regions in China, the results indicate: (1) From 2000 to 2020, the global Moran's I index for CO2 emissions generally shows a declining trend, with high-emission areas clustering increasingly in the northern regions; (2) CO2 emissions exhibit an accelerating upward trend with the progression of population urbanization, with significant regional disparities across eastern, central, and western China; (3) Energy transition policies and the establishment of a carbon emissions trading system are effective in reducing CO2 emissions; (4) During the process of population urbanization, it is essential to consider urban environmental carrying capacity and employment guidance to ensure a fair energy transition.
人口城市化极大地影响了城市二氧化碳(CO2)排放量。随着城市面积的扩大和人口的增长,对能源和资源的需求也随之增加,导致二氧化碳排放量上升。了解这些因素之间的客观规律和关联机制对于促进低碳和环境可持续的城市实践至关重要。本研究利用空间自回归(SAR)模型探讨人口城市化对二氧化碳排放的影响,并创新性地研究了政策和人口因素在这一过程中的作用。通过对中国 30 个具有代表性的省级行政区进行研究,结果表明(1)从 2000 年到 2020 年,全球 CO2 排放的莫兰 I 指数总体呈下降趋势,高排放地区越来越多地聚集在北方地区;(2)随着人口城镇化的推进,CO2 排放呈加速上升趋势,东、中、西部地区差异显著;(3)能源转型政策和碳排放交易体系的建立能够有效减少 CO2 排放;(4)在人口城镇化过程中,必须考虑城市环境承载能力和就业导向,确保能源转型的公平性。
期刊介绍:
Journal of Geochemical Exploration is mostly dedicated to publication of original studies in exploration and environmental geochemistry and related topics.
Contributions considered of prevalent interest for the journal include researches based on the application of innovative methods to:
define the genesis and the evolution of mineral deposits including transfer of elements in large-scale mineralized areas.
analyze complex systems at the boundaries between bio-geochemistry, metal transport and mineral accumulation.
evaluate effects of historical mining activities on the surface environment.
trace pollutant sources and define their fate and transport models in the near-surface and surface environments involving solid, fluid and aerial matrices.
assess and quantify natural and technogenic radioactivity in the environment.
determine geochemical anomalies and set baseline reference values using compositional data analysis, multivariate statistics and geo-spatial analysis.
assess the impacts of anthropogenic contamination on ecosystems and human health at local and regional scale to prioritize and classify risks through deterministic and stochastic approaches.
Papers dedicated to the presentation of newly developed methods in analytical geochemistry to be applied in the field or in laboratory are also within the topics of interest for the journal.
