Different ornamental periods meteorological prediction models of Populus euphratica were established based on the observed leaf color change information and meteorological data in Ejina from 2011 to 2021.The characteristics of yellow leaf phenology landscape variation and relationship between different ornamental periods and meteorological conditions were analyzed,The results showed that the appearance of yellow leaf phenological landscape showed a delayed trend in the past 11 years,and the leaf discoloration time was various in different years.The average yellow leaf period was 27.7 days.Temperature is the most significant meteorological factor affecting the discoloration and the landscape duration time of Populus euphratica.The temperature in September is positively correlated with the entry date of the best viewer period,low temperature will make leaf color turn earlier.Sufficient sunshine in the early months is conducive to promoting the formation of yellow leaf phenology landscape.In October,low temperatures and strong winds accelerate the defoliation,leading to an earlier end of the landscape.Meteorological prediction models were tested in 2022,the forecast accuracy was high and could be applied in business.
