亚高山森林树木生长响应气候变化研究的前沿和挑战
Frontiers and challenges of tree growth response to climate change in subalpine forests
摘要
Abstract
Subalpine forests,playing an important role in maintaining biodiversity and regional water and carbon balance,are highly sensitive to global climate changes.In the context of global climate change,response and adaptation of subalpine forests are among the key scientific issues of terrestrial ecosystems.Tree growth is an important reflection of changes in forest ecosystems.This paper summarizes the diverse patterns of subalpine tree growth along altitudinal gradients,and sums up potential mechanisms underlying the different growth responses of subalpine trees,which included"temperature and precipitation effect hypothesis","carbon supply limitation hypothesis","carbon utilization limitation hypothesis"and"the influence of underground ecological processes".Finally,the shorting-comings of these existing hypothesizes are discussed,the importance of hydraulics character of trees in regulating ecological processes is disclosed,and the future research directions are prospected.关键词
