摘要: 近年来,全球变暖对植物春季物候期产生了显著影响。很多研究报道了中国地区木本植物春季物候期变化的时空格局,但在同处于北半球温带地区的欧洲则相关研究较少。为了增进物候变化及其对气候变化响应规律的区域对比,本研究利用欧洲地区展叶始期(1980—2014年)数据和相应的气象数据,研究欧洲七叶树、垂枝桦、欧洲山毛榉和夏栎4种典型木本植物展叶始期的时空变化格局,并识别影响物候变化的主要气候因子。结果表明: 1980—2014年,研究区4种植物的展叶始期以3.3~7.5 d·10 a-1的趋势显著提前。展叶始期自南向北以每纬度2.03~3.19 d的速率推迟,自西向东以每经度0.19~0.80 d的速率推迟(除欧洲山毛榉外),海拔自低到高以2.25~3.44 d·100 m-1的速率推迟。展叶始期的提前主要与春季温度的增高和冬春季降水量的增加有关,而秋冬季温度的升高对展叶始期有一定的推迟效应。

Abstract: Over the past decades, global warming significantly affected the spring phenology of plants. Many studies have reported the temporal and spatial patterns of spring phenological changes in China, but relatively less is known for that in Europe, which is also located in the temperate area of the Northern Hemisphere. To facilitate the regional comparison of phenological change and understand its response to climate change, we used the data of first leaf date (FLD) in Europe (1980-2014) and the corresponding meteorological data to examine the spatiotemporal variations in leaf-out phenology of four typical tree species (Aesculus hippocastanum, Betula pendula, Fagus sylvatica, and Quercus robur), and to identify the major climatic factors driving such variations. The results showed that the FLD of the four species in the study area advanced by 3.3-7.5 d·10 a-1 during 1980-2014. The FLD was delayed at a rate of 2.03-3.19 d per degree of latitude from south to north, of 0.19-0.80 d per degree of longitude from west to East (except for Fagus sylvatica), of 2.25-3.44 d·100 m-1 from low to high elevation. The advances in the FLD were mainly attributed to the increases of temperature in spring and the increases of precipitation in spring and winter. The rise of temperature in autumn and winter would delay FLD.
