Abstract: Using the phenological observation data and the corresponding temperature,precipitation,and accumulated temperature in Liaoning province from 1981 to 2015,the characteristics of growth stages of Salix matsudana and their response to climate change were analyzed based on the linear tendency rate and trend coefficient methods.The results show that during the stages of bud opening,leaf expansion,bud or inflorescence emergence,and defoliation,Salix matsudana are all sensitive to changes in temperature.With the increase of temperature,the leaf expansion stage of Salix matsudana shows an ahead of time trend;the bud or inflorescence emergence and defoliation stages show a lag behind trend with a climatic trend rate of 0.8,2.3 and 3.8 days per decade,respectively;and the whole growing stage extends 7.0 days from 1981 to 2015.
