摘要: 以“一带一路”区域为研究区,基于1990−2018年的逐月历史气候数据和1981−2016年的逐年植被物候数据,采用趋势分析和统计分析等方法研究极端气候事件和植被物候的时空变化规律,并选取欧洲东南部耕地、中国北部内蒙古草原、印度中部耕地和泰国北部耕地为典型农业区,分析典型极端气候事件对生长季的影响规律。结果表明:(1)“一带一路”区域的极端气候事件主要以极端热事件和极端冷事件为主,且总体上呈现增加的趋势。极端高温事件的增加趋势明显,而极端低温事件则表现出减少的趋势;(2)生长季始期(SOS)、生长季末期(EOS)和生长季长度(LOS)总体上随纬度位置层状变化,海拔和降水也显著影响生长季。在全球变暖的影响下,“一带一路”区域大部分地区的SOS呈提前的趋势,而EOS呈延后的趋势,这导致了LOS的普遍延长;(3)当极端高温事件发生时,SOS普遍提前,而EOS普遍延后。极端低温事件则会导致SOS的延迟和EOS的提前。此外,极端气候事件越剧烈,对植被物候的影响越大。

Abstract: Taking “One Belt and One Road” region as the research area, based on monthly historical climate data from 1990 to 2018 and annual vegetation phenology data from 1981 to 2016, trend analysis and statistical analysis are used to study spatiotemporal variation of extreme climate events and vegetation phenology, and select cultivated land in Southeast Europe, Inner Mongolia grassland in China, cultivated land in the Indian mainland, and cultivated land in northern Thailand as typical agricultural regions, and analyze the influence of typical extreme climate events on the growing season. The results showed that, (1) the extreme climate events in “One Belt and One Road” region are mainly extreme warm and cool events, and generally show an increasing trend. The increasing trend of extreme high temperature events is obvious, while extreme low temperature events show a decreasing trend. (2) Start of Season (SOS), End of Season (EOS) and the Length of Season (LOS) are generally layered with latitude, altitude and precipitation also significantly affect the growing season. Under the influence of global warming, SOS in most areas of “One Belt and One Road” region has a trend of advancement, while EOS has a trend of delay, which leads to a general extension of LOS. (3) When an extreme high temperature event occurs, SOS generally early, while EOS generally postponed. Extreme low temperature events will cause the delay of SOS and the advance of EOS. In addition, the more severe the extreme climate events, the greater the impact on vegetation phenology.
