中文摘要: 为了探讨本溪山区气候变化对木本植物物候的影响,利用19802012年国家农业气象本溪县观测站旱柳物候期资料和气温、降水、日照等资料,运用线性倾向率和趋势系数等分析方法,研究了本溪山区旱柳物候期对气候变化的响应。结果表明:在近33年本溪山区气温呈明显的升温趋势变化,升温速率为0.45℃/10 a,降水和日照呈波动性减小趋势变化,降水量波动幅度较大,最大降雨量与最小降雨量差异大。旱柳芽开放期呈明显的延后趋势变化,其线性倾向率为2.4 d/10 a;开花始期呈拖后趋势变化,线性倾向率为0.35 d/10 a;旱柳变色始期和落叶始期均呈显著的延后趋势,其线性倾向率分别为7.27 d/10 a 和5.52 d/10 a。温度对旱柳物候影响最为显著,降水和日照对物候期的变化也有一定的影响。
英文摘要: In order to explore impacts of climate change on woody plant phenology in Benxi Mountainouse area,the phenophases change of woody plant and its responses to climate change were analyzed. The study used methods of linear trend and trend coefficient, and based on the data of Salix phenology of national agrometeorological station and temperature, precipitation, sunshine from 1980 to 2012 in Benxi County. The results showed that the temperature had a significant warming trend in the past 33 years, its increasing rate was 0.45℃/10 a, the precipitation and sunshine had a declining volatility trends and the precipitation showed great volatility, the range between the maximum and the minimum rainfall was big. The trend of buds opening was significantly delayed, its linear rate was 2.4 d/10 a. Flowering period was also delayed, its linear rate was 0.35 d/10 a. The start of discolor and fallen leaves showed significantly delayed trends, the rates were 7.27 d/10 a and 5.52 d/10 a respectively. Influence of Salix phenology of the temperature was significant, and the phenology changes of precipitation and sunshine had certain impact.
