Response of Typical Plant Phenology to Climate Change in Fenyang City
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.
