同属不同种桦树径向生长对气候变化响应的异同
Differences and similarities of radial growth responses of Betula species in the same genus to climate change
[目的]白桦(Betula platyphylla)和枫桦(Betula costata)是东北森林中重要的两种阔叶树种,但二者的生长对气候变暖和干旱的反应尚不完全清楚。探讨小兴安岭地区阔叶红松(Pinus koraiensis)林内白桦和伴生种枫桦生长对气候变化响应异同具有重要意义。[方法]选取伊春市五营林场中海拔高度相近且长势良好的白桦和枫桦,采用树木年轮学的方法研究了两种桦树径向生长与气候的关系。[结果]2 个树种径向生长与气候关系既存在相…查看全部>>
[Objective]Betula platyphylla and Betula costata are two important broadleaved tree species in temperate forests,but how their growth responds to warming and drought is not completely clear.[Method]We collected 122 core samples of B.platyphylla and B.costata in Yichun,China,and used dendrochronology methods to study how the two birches respond to and adapt to climate change recently.[Result]We discovered that there were both similarities and differences in t…查看全部>>
