摘　　要：为了进一步明确汾阳市几种典型植物物候对气候变化的响应,利用1996—2023年汾阳市气象站物候期资料,采用线性趋势估计、相关分析、一元线性回归等方法,分析物候变化及其对气候变化的响应。结果表明:1996—2023年,小叶杨、榆树、蒲公英、车前、苍耳的展叶盛期均呈现提前趋势,小叶杨、榆树落叶末期和车前黄枯普期呈现推后趋势,蒲公英和苍耳黄枯普期呈现提前趋势。5种植物的展叶盛期,小叶杨、榆树、蒲公英、车前受春季气温影响较大,与3月气温相关性强;苍耳受春季降水量影响较大,与9月气温相关性强。5种植物的黄枯普期或落叶末期,小叶杨和榆树受秋季气温影响较大,分别与9月、11月气温相关性强;蒲公英和车前受秋季日照时数影响较大,分别与9月、10月日照时数相关性强;苍耳受春季气温影响较大,与4月气温相关性强。In order to further clarify the response of phenology of several typical plants to climate change in Fenyang City,using phenological data from meteorological stations in Fenyang City during 1996-2023,the phenological change and its response to climate change were analyzed by linear trend estimation,correlation analysis and unary linear regression.The results showed that there was advanced trend of the mid leaf un⁃folding of Populus simonii,Ulmus pumila,Taraxacum mongolicum,Asiatic plantain and Xanthium sibiricum.There was delayed trend of the withering period of Populus simonii,Ulmus pumila and leaf fully defoliation of Asiatic plantain.There was advanced trend of the withering period of the Taraxacum mongolicum and Xanthium sibiricum.The mid leaf unfolding of Populus simonii,Ulmus pumila,Taraxacum mongolicum,Asiat⁃ic plantain was greatly affected by spring temperature and had a strong correlation with March temperature.The mid leaf unfolding of Xanthium sibiricum was greatly affected by spring precipitation and had a strong correlation with September temperature.The leaf fully defoliation of Popu⁃lus simonii and Ulmus pumila were greatly affected by autumn temperatures and had strong correlations with temperatures in September and No⁃vember,respectively.The withering period of Taraxacum mongolicum and Asiatic plantain were greatly affected by autumn sunshine duration and had strong correlations with sunshine duration in September and October,respectively.The withering period of Xanthium sibiricum was greatly affected by spring temperature and had a strong correlation with April temperature.
