为进一步推动学院科研高质量发展，我院推出“城市与环境学院博雅讲坛”系列活动，通过开展系列学术讲座，与同行共同分享学科前沿，交流学科知识、理论与信息，为师生提供一个观点交流、思想碰撞的平台。本期讲坛特邀美国农业部林务局资深研究员、哈佛大学森林学院资深研究员、美国生态学会会士潘愉德研究员作为主讲人。

1 报告简介

For achieving net-zero greenhouse gas emissions by 2050, one of the most challenging elements is the need of “nature solutions” for large-scale “negative missions” to compensate for the inability to eliminate all emissions from fossil fuels. As forests are the dominant component of the land carbon sink, we need to know how much atmospheric carbon the world’s forests have been sequestering, where it is stored, and whether recent trends are consistent with the desired strengthening of Earth’s land sink. In the recent published study (Pan et al., 2024, Nature 631, 563–569), an international forest carbon study group constructed a global record of forest inventory measurements from 1990 through 2019 based on milliohms of forest inventory plots across the world, and estimated global forest carbon stocks and sinks, and their changes over the last three decades for countries, regions and globe. The estimates of the forest land carbon sinks are largely independent of other modeling-based approaches and provide ground data-based benchmarks for complementing other top-down studies. Based on the observed changes in global forest carbon sinks, the study also made some suggestions for sustaining and strengthening valuable forest carbon sinks and other ecosystem services in the future via forest management approaches and relevant environmental policies.
