摘　　要：利用内蒙古扎兰屯气象观测站1995—2020年木本植物旱柳和动物家燕的物候观测资料和气温观测资料,采用气候倾向率和多元回归等研究方法,对大兴安岭东麓26 a来旱柳和家燕物候期在气候变暖过程中的变化进行了分析。结果表明:近26 a来大兴安岭东麓旱柳和家燕的春季物候期明显提前,且与气温上升均表现为负相关关系,旱柳春季展叶始期的年际波动与4月平均气温呈显著负相关关系,家燕始见期与1月1日至平均始见期期间≥10℃有效积温呈不显著的负相关关系。Based on the phenological observation data and temperature observation data of woody plant Salix matsudana and Hirundo rustica from 1995 to 2020 at Zhalantun meteorological observation station in Inner Mongolia,the research methods such as climatic trend rate and multiple regression were used to analyze the phenology changes of Salix matsudana and Hirundo rustica in 26 years at the eastern foot of Daxing’anling Mountain in the period of climate warming.The results show that the spring phenological period of Salix matsudana and Hirundo rustica has been significantly advanced at the eastern foot of Daxing’anling Mountain in the past 26 years,and has a negative correlation with the rise in temperature.There was a significant negative correlation between the first-seeing period of Salix matsudana and the average temperature in April,and there was no significant negative correlation between the first-seeing period of Hirundo rustica and the effective accumulated temperature≥10℃from January 1 to the average first-seeing period.
