中国城市在全球碳减排中扮演着核心角色,然而中国城市间巨大的经济发展差异深刻影响了中国城市减排的进程.城际供应链连接了城市的生产和消费,被认为是塑造地区分化和减排疲软的因素之一,但该效应在先前的研究中往往没有得到充分的考虑.本文对2012年中国309个城市的供应链进行建模.利用该模型,我们揭示了城市间存在显著的碳不平等:中国最富裕的10个城市的人均碳足迹相当于美国的水平,而中国一半的城市则低于全球平均水平.然而,这种显著的碳不平等也蕴含着新的减排机遇,即对32个超高排放城市,根据其富裕程度、产业结构和供应链的位置采取不同的减排策略,将可创造高达1.4亿吨的碳配额,距离碳达峰值增加了30%的空间.额外的碳配额足够使经济发展欠发达人口的平均生活水平达到中上收入水平,突出了城市层面的合作机制具有促进公平和减排目标收敛的巨大潜力.

Paddy fields play an important role in global carbon(C) cycling and are an important source of methane(CH_(4)) emissions. Insights into the processes influencing the dynamics of soil organic C(SOC) in paddy fields are essential for maintaining global soil C stocks and mitigating climate change. Periphytic biofilms composed of microalgae, bacteria, and other microorganisms are ubiquitous in paddy fields, where they directly mediate the transfer of elements at the soil-water interface. However, their contributions to C turnover and exchange have been largely neglected. Periphytic biofilms affect and participate in soil C dynamics by altering both abiotic(e.g., pH and redox potential) and biotic conditions(e.g., microbial community composition and metabolism). This review summarizes the contributions of periphytic biofilms to soil C cycling processes, including carbon dioxide fixation, SOC mineralization, and CH_(4) emissions. Future research should be focused on: i) the mechanisms underlying periphytic biofilm-induced C fixation and turnover and ii) quantifying the contributions of periphytic biofilms to soil C uptake, stabilization, and sequestration in paddy fields.
