摘要:为了揭示哈尔滨市3种灌木物候对气候变化的响应机制,根据1963—2008年哈尔滨市气象资料与黑龙江省森林植物园珍珠梅、紫丁香和东北连翘3种灌木物候观测资料,采用相关分析和一元线性回归方法,对3种灌木物候期(芽开放期、展叶始期、开花始期、脱落末期)的变化趋势及其对气候变化的响应特征进行分析。结果显示:哈尔滨市1963年以来气温呈显著上升趋势,且低温增加最显著;珍珠梅、紫丁香、东北连翘的芽开放期分别提前了7.5、2.7、8.1 d,展叶始期分别提前了9.2、9.9、18.4 d,开花始期分别提前了17.8、8.4、7.5 d,珍珠梅与紫丁香脱落末期分别推后了17.3、13.1 d,东北连翘脱落末期提前了11.9 d;春季物候期的早晚主要受春季气温的影响,特别是春季物候期发生的当月和上一月的平均气温对物候期影响最为显著;东北连翘脱落末期与10月份平均气温呈显著负相关,其他2种灌木脱落末期与温度之间存在不显著的正相关关系;当4月份温度上升1℃,珍珠梅、紫丁香、东北连翘的芽开放期分别提前1.7、2.4、3.0 d,展叶始期分别提前2.8、2.8、3.6 d,开花始期分别提前2.7、3.2、2.2 d。
A study was conducted to reveal the response mechanism of three shrub species(Sorbaria sorbifolia,Syringa oblata,and Forsythia mandshurica) to climate change according to the meteorological data obtained in Harbin and the phonological observation data of three shrub species in Heilongjiang Forest Botanical Garden during 1963-2008.The correlation analysis and simple linear regression were used to analyze the changing trend in phenophases(bud burst,beginning of leaf expansion,opening of the first flower and end of leaf-fall) of the three species of shrubs and their responses to climate change.Results show that the temperature in Harbin has risen significantly since 1963,especially for the minimum temperature.Bud burst of S.sorbifolia,S.oblate and F.mandshurica advanced by 7.5,2.7 and 8.1 days,beginning of leaf expansion by 9.2,9.9 and 18.4 days,and opening of the first flower by 17.8,8.4 and 7.5 days,respectively.End of leaf-fall of S.sorbifolia and S.oblata postponed 17.3 and 13.1 days,respectively,and that of F.mandshurica advanced by 11.9 days.The phenophases in spring was mainly affected by the temperature for spring,especially average temperature in the current month and the previous month.The end of leaf-fall of F.mandshurica had a significant negative correlation with the average temperature in October,and that of the other two shrub species had unobvious positive correlations with the average temperature.A one-degree Celsius average temperature rise in March could advance the bud burst of S.sorbifolia,S.oblata and F.mandshurica by 1.7,2.4 and 3.0 days,beginning of leaf expansion by 2.8,2.8 and 3.6 days,opening of the first flower by 2.7,3.2 and 2.2 days,respectively.
