气候变化对植物多样性的影响研究综述

Review on the impact of climate change on plant diversity

植物多样性是生态系统结构和功能的基础,气候变化已对其产生了深刻的影响,甚至于严重威胁。植物多样性的减少或丧失必然会影响生态系统结构和功能的稳定性,导致严重的生态、经济和社会后果。植物多样性对气候变化的响应受控于气温和水分的动态平衡。本文系统总结了气候变暖和降水格局变化对植物多样性的影响,分析了气候变化对不同生态系统、群落类型、尺度范围(全球尺度、区域尺度、局地尺度)内植物多样性的影响,并归纳了差异的主要影响因素。最后对未来的研究方向做了展望。

Plant diversity is the basis for ecosystem structure and function,and climate change has had a profound impact on it,even a serious threat.The decrease or loss of plant diversity necessarily affects the stability of ecosystem structure and function,lead to serious ecological,economic and social consequences.Studies have shown that the response of plant diversity to climate change is controlled by the dynamic balance of temperature and water.This research systematically introduced the effects of climate warming and precipitation pattern change on plant diversity.In this report,the impacts of climate change on plant diversity in different ecosystems,community types and scales(global,regional and local scale)are analyzed and the main factors that influence the difference were summarized.We also propose research hotspots and directions for future plant diversity research in different environmental conditions.
