摘　　要：凋落物是森林生态系统中养分归还的主要形式,其分解决定着土壤有机物质的存储与周转。随着全球变暖日趋明显,气候变暖对森林凋落物的影响引起了人们的极大关注,取得了较多研究成果,但部分研究结果仍存在争议,研究亟待加强。文中分别从凋落物产量、结构和组成、分解速率等方面综述全球变暖对森林凋落物影响的研究进展,比较了全球变暖不同模拟研究方法的优缺点,提出统一研究方法、加强长期动态观测、强化森林凋落物对环境变化的适应机制研究等建议,以期为全面精准评估全球变暖对森林凋落物的影响提供科学参考。Litter is the main form that returns nutrients into forest ecosystem,and its decomposition determines the storage and turnover of soil organic matter.As the global warming is increasingly pronounced,the impacts of climate warming on forest litters have attracted great attention,and fruitful research results have been achieved.However,there are some controversies for some studies,and the research in this field still needs to be strengthened.This paper reviews the impact of global warming on forest litters in terms of production,structure and composition,and decomposition rate of forest litters,compares the advantages and disadvantages of different research methods for global warming simulation,and proposes the suggestions including unifying research methods,carrying out long-term dynamic observation experiments,and boosting the research on the adaptation mechanism of forest litters to environmental changes.The study is expected to provide a scientific basis for completely and accurately assessing the impacts of global warming on forest litters.
