摘要：[目的]比较同一气候区不同栎类树种生长对气候要素的响应差异,特别是在分布边缘不同树种的种内种间差别。[方法]利用树木年轮学方法,分析了我国暖温带北缘3种优势落叶栎树(蒙古栎、栓皮栎和麻栎)径向生长对气候要素的响应差异;同时利用混合线性效应模型构建了3个树种径向生长与气候的关系,并基于未来气候情景(RCP2.6和RCP8.5)预测了其未来生长趋势。[结果]同一地区栎类树种年表具有较高的相似性,而不同地区间差异较大;在径向生长对气候响应方面,同一地区的不同栎类树种和不同地区同一栎类树种也存在一定差别。其中北京地区的3种栎类树种的径向生长与当年6月气温呈负相关关系,但在辽宁仙人洞地区却与气温无显著相关关系;北京地区的麻栎、河北地区的蒙古栎、辽宁大黑山地区的栓皮栎的径向生长均受降水条件限制。模型预测显示,至本世纪末,北京地区和辽宁大黑山地区栎类树种的径向生长呈现下降趋势;而辽宁仙人洞地区栎类树种径向生长呈增加趋势。[结论]我国暖温带北缘不同地区的栎类树种对气候要素的响应存在显著差别,主要为取样地区的气候所支配,下一步尚需结合林分及立地因子,来厘清各类环境要素的相对贡献度。
[Objective]The aim of this study was to compare the differences of growth responses of different Quercus species to climatic factors in the same climatic region,and pay special attention to the intraand inter-species differences at the margins of tree species distribution.[Methods]The response of radial growth of three dominant deciduous Quercus species(Quercus mongolica,Q.variabilis and Q.acutissima)to climatic factors in the northern margin of warm temperate zone in China was analyzed by dendrochronological method.At the same time,the relationship between radial growth and climate of three tree species was constructed by using mixed linear effect model,and their future growth trends were predicted based on future climate scenarios(RCP2.6 and RCP8.5).[Results]Chronology of Quercus species in the same area presented high similarity,but there were large differences among different areas.In terms of the response of radial growth to climate,the chronology of different Quercus species in the same region and the same Quercus species in different regions are also different.The radial growth of three Quercus species in Beijing was negatively correlated with the current June temperature,but there was no significant correlation with the temperature in Xianrendong(Liaoning Province).The radial growth of Q.acutissima in Beijing,Q.mongolica in Hebei and Q.variabilis in Dahei Mountain(Liaoning Province)were all limited by precipitation.The modeling results showed that by the end of this century,the radial growth of Quercus species in Beijing and Dahei Mountain would show a decreasing trend,while that in Xianrendong(Liaoning Province)an increasing trend.[Conclusion]There are significant differences in the growth responses of Quercus species to climate factors in different areas of the northern margin of warm temperate zone in China,which are mainly dominated by the climate features of sampling regions.In the next step,it should be necessary to clarify the relative contribution of various environmental factors(e.g.,stand features and site factors)to radial growth of Quercus species.
