基于多尺度林线对气候变化响应研究综述

Research Overview on the Response Mechanism between Timberline and Climate Change Based on Different Scales

全球气候变化研究的焦点之一就是根据物种特征和植被类型分布与气候的关系,反演地质时期的气候特征,预测未来气候变化趋势。林线作为气候变化的"强信号",是全球气候与环境变化的敏感指示器。不同尺度林线研究差异显著,均可反映诸多尺度气候变化信息。基于此,文章创新从样点尺度、景观尺度和区域尺度分别阐述了林线研究方向、国内外研究现状与方法新动向。通过新视角较全面系统地概括了林线与气候变化的响应机制。

Inversing the climate characteristics in geologic time and predicting the future trend of climate change based on the relationship between species characteristics and climate as well as vegetation type pattern is one of the focus researches in global climate change. Timberline as a ＂strong signal＂ of climate change is a sensitive indicator in global climate and environmental change. It is a significant differences timberline study under the different scales, all of which reflect the information of climate change under the different scales. Based on this background, this article illustrates timberline research direction, research status and new methods and new trends depending on the sample point scale, landscape scale and regional scale, respectively. As a result, we summarized the response mechanism of timberline to climate change comprehensively and systematically based on this new perspective.
