摘　　要：果树物候期对气候变暖的响应受到人们普遍关注。从气候变暖对果树物候期的影响、驱动果树物候期变化的因子和果树物候期监测方法3个方面回顾了果树物候期研究进展,并提出未来果树物候期的研究重点。果树物候期变化是多因子综合作用的结果,气候变暖背景下我国大部地区果树春季物候期提前,秋季物候期推迟。相比传统地面观测,利用遥感方法的果树物候期研究实现了果树物候期观测由点到面的空间转换,是物候期研究的一个前沿领域。未来应将地面观测、模型模拟和遥感监测手段有效结合进行果树物候期交互验证,同时加强多因子的果树物候期分子机制研究。Fruit tree phenology has aroused public and scientific attention due to the growing evidence that the timing of development stages is largely dependent on environmental factors.Particularly,as fruit tree phenology events are highly sensitive to climate fluctuations,the timing of these events has been used as the most salient and sensitive bio-indicators of climate change.Studies have reported shifts in fruit tree phenology due to warming temperatures,leading to earlier spring and later autumn phenology,with potential impacts on the safety of fruit production.Modelling,assessing and monitoring of fruit tree phenological dynamics are therefore key requirements to improve the understanding of how fruit tree responds to global warming.In order to improve the understanding of fruit tree phenology,this paper has systematically reviewed important progresses in researches on fruit tree phenology,focusing on fruit tree phenology and climate warming,the driving factors on phenological phenomena and phenology monitoring methods.Then,we pointed out some main research aspects in the near future.Among them,previous studies have indicated that changes in spring phenology of fruit crops as a result of increased temperature may manifest as advancement,delay or no change.These inconsistent responses are due to the unbalanced relationship between forcing and chilling effects,i.e.variation in chilling effects due to winter warming and changes in forcing effects related to spring warming.The driving factors of main fruit tree phenological change are environmental conditions(air temperature,humidity,etc.)and agricultural management,and thus a comprehensive understanding of the driving factors affecting fruit tree phenology can benefit to fruit production.Furthermore,to better understand the chilling effects of winter temperature and forcing effects of spring temperature on fruit tree spring phenology,several models have been developed to calculate chilling and forcing accumulation.For example,results from the Chill Overlap model were
