物候学是一种反映植物繁殖周期的生物学现象，是反映气候变化及其对植物影响的重要信号。过去50年的大量工作已经量化了植物物候期对当地温度和降雨量变化的反应程度。该学科最初通过分析地面物候观测进行，最近包括来自卫星图像和数字重复摄影的物候期指标。随着研究的进展，植物物候对气候变率和变化的反应既有地点特异性，也有物种特异性，这一点已经变得很明显。植物受温度和降雨量变化影响的程度及其内在的适应能力将最终决定持续生态稳定和粮食安全的潜力。我们回顾了植物物候-气候随时间变化的方法，分析了气候变异性表现出明显因果作用的地区和物候期，最后反思了物候气候变化研究在更广泛的生物地理背景下的应用。
Phenology, the timing of annually recurrent reproductive biological events, provides a critical signal of climate variability and change effects on plants. Considerable work over the past five decades has quantified the extent to which plant phenophases are responding to local changes in temperature and rainfall. Originally undertaken through the analysis of ground-based phenological observations, the discipline has more recently included phenophase indicators from satellite images and digital repeat photography. With research advances it has become evident that the responses of plant phenology to climate variability and change are both location- and species-specific. The extent to which plants are affected by changes in temperature and rainfall, their intrinsic adaptation capacity, will ultimately determine the potential for sustained ecological stability and food security. We review methodological approaches to plant phenological-climate change over time, analyse the regions and phenophases for which climate variability demonstrates a clear causal role, and finally reflect on the applications of phenological climate change investigations in broader biogeographical contexts.
