Spring phenology observational data of typical ligneous plants from agricultural observation stations in Bachu county,Yicheng county,Makit county & Kashgar city of Kashgar prefecture and the meteorological data of corresponding period in these places,and the methods of linear tendency estimation,T test,correlation analysis etc were applied to analyze the change tendency of temperature and spring phenology of ligneous plants in these places and to analyze the temperature influences on spring phenology of the plants. Results show that the annual average temperature presented rising trend,the warming tendency was the most outstanding since 21 century; Spring phenology presented advanced tendency generally; on average,the spring phenology has been advanced 8d gradually in Kashgar prefecture during recent 28a. Spring phenology was the most sensitive to the average temperature of the first month during the earlier stage of phenology. 1℃ rise of average temperature could lead to 1.5-3.4 ds ahead of spring phenology in outstanding sensitive period. The correlation between spring phenology and annual average temperature was clear,the rise of annual average temperature could lead the spring phenology ahead, vice versa. 1℃ rise of annual average temperature could lead to 3.1-9.0ds ahead of spring phenology.
