摘要: 凋落物分解是影响土壤碳储量、养分有效性和植物生产力的全球生物地球化学循环的关键组成部分。气候变化的影响可以是直接或间接的，例如通过凋落物质量的变化直接影响，亦或通过微生物群落的活动等间接影响，但气候变化对于凋落物分解的影响，其相对重要性还不清楚。尤其针对森林、草原、湿地等不同生态系统也有很大不同，而且多因素的影响也会使得气候变暖对凋落物的影响更为复杂。全球变暖背景下物种多样性和凋落物分解及其对温度升高的响应是生态学研究的热点内容，是探究生态系统养分循环响应全球变暖的关键。基于国内外学者大多只针对某一陆地生态系统类型的凋落物进行评价，大多报道只关于单一生态系统的凋落物分解过程及影响因素等，相关报道比较分散，具有局限性，因此本文通过归纳综述了对于不同生态系统凋落物如何响应全球气候变暖的问题研究，为完善我国在全球气候变暖背景下不同类型凋落物的进一步研究提供参考。
Abstract: Litter decomposition is a key component of the global biogeochemical cycle that affects soil carbon storage, nutrient availability, and plant productivity. The impact of climate change can be direct or indirect, for example, directly through changes in litter quality, or indirectly through the activities of microbial communities, but the relative importance of the impact of climate change on litter decomposition is still unclear. Especially for different ecosystems such as forests, grasslands, wetlands, etc., the impact of multiple factors will also make the impact of climate warming on litter more complicated. Species diversity and litter decomposition in the context of global warming and their response to temperature rise are hot topics in ecological research, are the key to exploring ecosystem nutrient cycles in response to global warming. Based on the fact that most domestic and foreign scholars only evaluate the litter of a certain type of terrestrial ecosystem, most of the reports only focus on the decomposition process and influencing factors of the litter of a single ecosystem. The related reports are scattered and have limitations. Therefore, this article summarizes the research on how the litter of different ecosystems responds to global warming provides a reference for further research on different types of litter in my country under the background of global warming.
