Abstract:

Plant phenology is an important indicator for natural environmental change. In the context of global change,the response of
plant phenology to climate changes and its simulation have been international focus issues. This paper discussed the significance of
study on plant phenology,and analyzed the effects of main environmental factors on the phenology such as temperature,water and
light. According to the result of domestic and foreign study on phenology,the paper reviewed the response of plant phenology to climate
change during the decades,and introduced the two basic phenological models,those are the models based on temperature or other environmental
factors and carbon balance. Although the latter model shows a stronger mechanism and modeled the phenology better,it is
inevitable that experiential formula between phenology and environmental factors ( temperature,water and nutrients) was used in the
model based on carbon balance. At last,based on the existing issue in phenological research,the direction of phenological research is
pointed out.

Key words: plant phenology, climate change, phenological model

摘要:

植物物候是指示自然环境变化的重要指标,在当前全球变化的大背景下,植物物候对气候变化的响应及其模拟已成为当前国际上研究的热点。本文探讨了植物物候研究的意义,分析了影响物候的温度、水分、光周期及其他因子等主要环境因子的作用,综述了植物物候近几十年来对气候变化的响应特征,重点介绍了当前动态物候模型的2 种基本类型,基于温度( 积温) 或其它环境变量的物候模型和基于碳平衡的物候模型,尽管后者机理性更强,模拟效果更好,但是仍无法彻底避免要应用与温度、水分等环境因子以及养分含量等的经验关系式。最后根据当前物候研究中存在的问题,讨论了未来物候研究的方向。
