| 摘 要： | 为了应对全球气候变化带来的挑战，2020年9月中国提出努力争取在2060年前实现碳中和。对此，生态系统固碳被寄予厚望；然而，生态学理论认为，成熟生态系统的碳输入输出趋于平衡，没有碳的净积累，也就没有碳汇功能，而未成熟的生态系统虽有碳的净积累并具有碳汇功能，但自然界任何未成熟生态系统从它建立的时候开始都在不断地向成熟生态系统演替，即任一生态系统演替的最终结果必然是碳输入输出达到平衡状态。由于森林生态系统碳库是陆地生态系统中最大的碳库，所以人们对其在碳中和上的贡献充满期待。本文以森林生态系统为例，分别考虑森林生态系统碳库的生物量碳库和土壤有机碳库，并基于全球最新研究成果，论证了森林生态系统土壤碳库积累过程具有长久的固碳功能，且不违背成熟生态系统碳输入输出趋于平衡的生态学理论，它能为实现碳中和目标做出贡献。

| Abstract: | To combat the challenges posed by global climate change, in September 2020, China proposed to strive to achieve carbon neutrality by 2060.However, according to ecological theory, the carbon input and output of mature ecosystems tend to be in balance, and there is no net accumulation of carbon and no carbon sink function, while immature ecosystems have a net accumulation of carbon and a carbon sink function, but any immature ecosystem in nature has been continuously replacing the mature ecosystem since it was established, that is, the end result of any ecosystem succession must be that carbon input and output are in equilibrium.Since forest ecosystems are the largest carbon pools in terrestrial ecosystems, their contribution to carbon neutrality is highly expected.Therefore, taking mature forest ecosystems as an example, considering their biomass carbon pools and soil organic carbon pools respectively, and based on the latest global research results, this paper demonstrates that the soil carbon pool accumulation process of mature forest ecosystems has a long-term carbon sequestration function, and does not contradict the ecological theory that the carbon input and output of mature ecosystem tend to be in balance, and it can contribute to the goal of carbon neutrality. |
