Carbon emission accounting is an important basis for global climate governance. Based on the consumption-based accounting(CBA) method, the characteristics of carbon flow between national, regional, and product processes could be more clearly reflected. Therefore, CBA is more conducive to clarifying the attribution of responsibilities between producers and consumers, with the principles of fairness and justice. By accounting for carbon emissions in typical countries from 1990 to 2019, we found that the CBA emissions are higher than the production-based accounting(PBA) emissions in major developed countries, while the results are reversed for developing countries. In the past 30 years, the CBA emissions in targeted developed countries generally have shown a downward trend, while in developing countries, they have shown an upward trend. CBA emissions in China have shown a continuous growth trend from 1990 to 2019, but the pace has slowed down significantly over the last decade. Meanwhile, the embodied carbon intensity of China's exports continues to decline, indicating that China is providing more green and low-carbon products to the world. Taking the PV industry as an example, this study further reveals the contribution of specific product industries to the country's carbon transfer through product carbon footprint analysis. In order to provide a scientific basis for global mitigation and climate governance, it is urgent to innovate a scientific, practical, and standardized CBA technology system.

高山树线被视为记录气候变化对树木和森林影响的生态监测器。迄今为止,大多数树线研究都集中在气候变化如何驱动树线动态的变化。然而,关于生物相互作用如何调节树线变化,特别是在树木更新这一树线动态的瓶颈方面,人们知之甚少。本研究假设种间和种内促进作用决定了高山树线树苗的定居和存活。为了验证这一假设,我们在青藏高原东南部的色季拉山高山树线交错区(海拔4300–4500 m)的3个生长生境(林冠内、林冠外和草地)中共计移植了630株不同年龄(4–6年、7–9年和10–15年)的急尖长苞冷杉(Abies georgei ***)幼苗,连续3年监测了移植后幼苗的微气候、高度生长、死亡率和叶片功能性状。结果发现,叶片功能性状的变化是由微气候驱动的。移植后,叶片可溶性糖和淀粉浓度以及C:P比增加,而叶面积减小。幼苗的资源利用逐渐转向更保守的策略,其背后机制主要受到了生理性状(非结构性碳水化合物和植物养分)的介导。同时,由结构方程模型发现太阳辐射、温度和水分条件在植物相互作用下,通过介导叶片形态性状的变化最终影响了幼苗的死亡率和年生长。上述研究结果表明,植物间的互利作用通过改变太阳辐射和叶片功能性状,最终在决定幼苗生长和存活上起到至关重要的作用,同时也为理解全球气候变化背景下高山树线动态变化的驱动机制提供了新的见解。
