摘要

近几十年来，南极半岛经历了相当程度的人为变暖。虽然低温层的反应已经明确，但以苔藓为主的陆地生态系统的反应尚未量化。利用谷歌地球引擎云处理工作流程对大地遥感卫星档案（1986-2021 年）进行的分析表明，整个南极半岛大面积绿化。可能的植被覆盖面积从 1986 年的 0.863 平方公里增加到 2021 年的 11.947 平方公里，与研究期间（1986-2021 年：0.317 平方公里/年）相比，近年来的变化速度加快（2016-2021 年：0.424 平方公里/年）。这一趋势与近期气候变暖导致的寒冷气候生态系统绿化的更广泛模式相呼应，表明南极半岛陆地生态系统及其长期功能将在未来发生广泛变化。

Sustained greening of the Antarctic Peninsula observed from satellites

The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems have not been quantified. Analysis of Landsat archives (1986–2021) using a Google Earth Engine cloud-processing workflow suggest widespread greening across the Antarctic Peninsula. The area of likely vegetation cover increased from 0.863 km2 in 1986 to 11.947 km2 in 2021, with an accelerated rate of change in recent years (2016–2021: 0.424 km2 yr−1) relative to the study period (1986–2021: 0.317 km2 yr−1). This trend echoes a wider pattern of greening in cold-climate ecosystems in response to recent warming, suggesting future widespread changes in the Antarctic Peninsula’s terrestrial ecosystems and their long-term functioning. Analyses of satellite observations from 1986 to 2021 suggest that the Antarctic Peninsula is greening at an accelerated rate.
