李晓霞----中国科学院青藏高原研究所

简介

个人简介

李晓霞，女，生于1986年3月，博士，助理研究员。主要研究方向为树轮生态学、树木形成层活动与气候变化等，前期研究主要通过建立藏东南海拔梯度带上树木形成层活动的监测网络，揭示限制高山林线树木、高山灌丛生长的气候阈值特征，以探讨高山树线形成机制。主要学术贡献：1）从形成层分裂、分化角度证实了最低温是影响藏东南树线乔木、高山灌木生长的主要气候因子；2）发现藏东南冷湿环境下，树木形成层活动低温阈值通过调节木质部分化开始与结束的时间从而控制着生长季长度和高山树线的形成，为理解高山树线形成机制提供了新视角。相关研究成果发表在Tree physiology、Science Bulletin、American Journal of Botany等国际期刊上。主持并参与国家自然科学基金青年基金、面上基金、国际合作与交流项目等多个研究项目。
