垂直带谱上植被群落对气候变化响应的研究进展

Review on the vegetation response to climate change in vertical zone spectrum

气候变化对垂直带谱的影响是长久以来的热点问题之一。但是目前大部分研究集中在利用遥感影像分析不同植被覆盖度和生物量上,对植被带谱上植被群落沿海拔上的迁移的研究相对较少。植被覆盖度和生物量变化(短期效应),和垂直带谱上植被群落的迁移(长期效应)均能反应植被对气候变化的响应。因此,我们以垂直带谱上植被群落的迁移为主线,分别综述了气候变暖对植被覆盖度和生物量的影响,垂直带谱上不同植被类型随气候变化在海拔梯度上的迁移,以及气候变化对垂直带谱上不同植被群落海拔梯度上分布带宽的影响。

The influence of climate change on vegetation vertical zone spectrum is one of the important research questions.However, current research focuses more in the dynamics of vegetation cover and biomass of different vegetation communities in vertical zone spectrum based on remote sensing approach under climate change. However, relatively less research emphasizes the upward shifting of different vegetation communities along elevational gradient. Both dynamics of cover or biomass(short-term response), and upward shifting of vegetation communities(long-term response) indicate vegetation response to climate change. Therefore, this paper provides a comprehensive review including the impact of climate change on vegetation cover and biomass, upward shifting and the elevational distribution change of different vegetation communities in the vertical zone spectrum.
