摘　　要：植物物候对气候变化非常敏感,可作为环境变化对植物生理活动影响的指示。植物物候的变化不仅可反映和预测全球环境的变化,还对地球物质循环和能量流动过程有着重要的影响。因此,结合植物生长背景,全面分析植物物候影响因素,探究植物物候对气候变化的响应是十分必要的。本文基于不同的气候类型下植物物候的研究,介绍了不同气候类型本身存在的气象、地域差异,总结不同气候类型下植物物候地域性特征;总结了热带亚热带气候、温带气候、寒带气候、高原山地气候4大类气候类型下植物物候变化及影响因素;讨论了当前物候研究的主要问题,并对未来研究进行了展望。综述表明,植物物候响应随气候类型呈现出不一致性,不同气候类型下影响植物物候的关键因素也不同。植物物候研究需结合植物生长环境,综合讨论相关影响因素。Background,aim,and scope The phenology of plants is sensitive to climate changes and is an indicator of several effects caused by environmental change.Variations in plants phenology not only reflect the evolution of the global environment,but also have important impacts on the earth material cycle and energy flow process.Previous studies have highlighted the inconsistency in the phenological response to climate change under diverse climate types.In addition,the key factors influencing the vegetation phenology varies with the regions.Generally,temperatures play a dominant role in controlling the plants phenology,however,other factors such as precipitation and light can also significantly alter the phenology in different regions.Therefore,combined with the background of plants growth,a comprehensive synthesis of factors affecting plant phenology is very necessary.Materials and methods In this paper,we did a literature review which comprise(1)the meteorological and territorial differences among diverse climate types as well as the regional characteristics of plants phenology under different climate types;(2)the phenological dynamics and dominant factors of plants phenology in four main kinds of climate types(tropical and subtropical climate,temperate climate,frigid climate and plateau mountain climate);(3)the discussion of the main problems of vegetation phenological studies and its prospect.This review is crucial to the research on the plants phenology variations under global change.Quantitative results and related contributions are summarized,and the unresolved issues for further study of the limitation in phenological research are discussed.Results The results showed that:(1)There were differences in spatial distribution of plants phenology in the world,and the latitudinal difference was found in the vegetation phenology.In the northern hemisphere in the high latitudes that is 40°N to the north of the area,the green-up date of vegetation from the south to the north showed a delayed trend.However,later occurrence
