      近日,公司焦亮副教授团队的研究论文《Assessing the stability of radial growth responses to climate change by two dominant conifer trees species in the Tianshan Mountains, northwest China》在国际著名学术期刊《Forest Ecology and Management》发表。该刊物为中国科学院一区Top杂志,近五年平均影响因子为3.524,是森林生态和管理领域较有影响力的国际期刊之一。

        随着20世纪下半叶全球气候变暖加剧,树木的径向生长表现出不稳定的气候响应,从而降低了基于树木年轮开展生长—气候生态关系研究的准确性。该论文对天山地区两个优势共生针叶树种西伯利亚落叶松(Larix sibirica)和雪岭云杉(Picea schrenkiana)进行了气候响应的稳定性评价,初步得出以下结论:生长季干旱是两个树种径向生长的主要限制因素:西伯利亚落叶松对前一年夏季平均温度发生了分异响应,而雪岭云杉对当年春季的平均温度、总降水量和标准化蒸散指数(SPEI)的响应稳定;西伯利亚落叶松表现出先增加后下降的生长趋势,而雪岭云杉呈现出持续降低的生长趋势。研究结果证实干旱半干旱环境下的山地森林生态系统会受到更严重的干旱胁迫,未来应根据物种对气候变化的响应特征采取不同的管理措施。

近几年,焦亮副教授研究团队依托树木年轮资料构建多时空尺度树木径向生长对气候变化的响应关系模型,围绕树木径向生长的分异响应、年龄效应、海拔影响等问题进行了系统分析,其系列研究成果分别在《Trees-Structure and Function》《Dendrochronologia》《Forests》等国际期刊上陆续发表。同时,其主持的《腾格里沙漠南缘优势针叶树种径向生长对气候变化的响应稳定性评估》也获得了国家自然科学基金项目的资助(项目编号41861006,资助经费40万元,执行年限20191月—202212月)。
