摘要: 利用1981-2015年辽宁省旱柳物候观测资料及同期的气温、降水资料,采用线性倾向率和趋势系数方法分析辽宁地区旱柳生长期的变化特征及其对气候变化的响应。结果表明:1981-2015年辽宁省旱柳芽开放期、展叶期、花蕾或花序出现期、落叶期均对前期的气温较敏感,随着气温的升高,旱柳展叶期整体呈提前的趋势,气候倾向率约为0.8 d/10 a;旱柳花蕾或花序出现期整体呈推迟的趋势,气候倾向率约为2.3 d/10 a;旱柳落叶期呈明显的延迟趋势,气候倾向率约为3.8 d/10 a。辽宁省旱柳生长期的长度随气温升高而延长,近35 a旱柳生长期的长度约延长了7.0 d。

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.
