摘要： 植物物候与植物的适应进化、物种间相互关系、生态系统的结构和功能密切相关，且对气候变化特别敏感，所以一直是进化生物学、植物生态学和气候变化生态学的研究热点和前沿科学问题。本综述基于草地植物物候研究的3个层次（个体-种群-群落）和7个物候序列（返青、现蕾、初花、初果、果后营养、初黄和枯黄期），阐述了不同层次物候序列及其相应持续期对气候变化响应过程的研究进展以及目前研究主要存在的问题，并在此基础上提出未来研究亟需关注的科学问题及展望，以期推动我国植物物候生态学研究发展。

Abstract: Plant phenology has always been a hotspot and frontier research in plant evolutionary biology, plant ecology, and climate change ecology, as it is closely associated with plant adaption and evolution, interspecies relationship, and ecosystem structure and functions, and it is greatly sensitive to climate change. Here, we review the main progresses and problems about the responses of the staring date and duration of phenological sequences to climate change based on three levels (i.e., individual, population, and community) with seven phenological sequences (i.e., onset of green-up, first budding-set, first flowering, first fruiting-set, nutrition after fruiting-set, first coloring, and complete coloring). We further proposed some scientific questions and prospects to promote the development of plant phenological studies in China.

Key words: Climate change, grassland plant, phenological hierarchy, phenological sequence
