摘要
总结了全球变化下植物物候研究的主要进展,针对该领域国内外的几个热点问题进行了讨论。植物物候研究的重心从以前的野外观测和初步统计分析逐步过渡到以揭示物候周期的调控机制和环境效应为主,研究手段从植物物候对环境变化做出反应的表象描述转移到多尺度、多要素耦合关系的综合分析。随着学科交叉研究的不断深入,植物物候研究从植物个体及居群适应性研究转向植物物候变化对生态系统、气候演变、农业生产乃至人类健康等方面影响的系统评估。并且在该转变过程中出现了几个关键性问题,如不同温度带大气温度与光周期对植物物候期贡献力问题、植物物候变化对气候变暖的非线性响应特征、群落水平上植物物候研究的复杂性、以及农业生态系统中作物物候研究的重要性等。对我国植物物候研究现状和管理体系中亟待解决的问题提出了建议。
