摘要
近40年来,气候变化导致青藏高原暖湿化,对森林、灌丛、草地、湿地和荒漠等生态系统的地理分布格局和功能产生了明显影响。灌丛、草地和湿地分布范围扩大、边界向西和高海拔区域扩展。气候变化影响下,青藏高原生态系统生产力、固碳和土壤保持能力得到改善,水源涵养变化在空间上表现出显著的异质性。气候变化对植物物候、植物生长速率、动植物分布范围和物种相互作用,以及生物多样性的显著影响,还有待更深入观测与研究。
In the past 40 years,climate change has led to the warming and humidification of the Tibetan Plateau,which has had a significant impact on the geographical distribution and function of ecosystems of forests,shrubs,grasslands,wetlands,and deserts.The distribution range of shrubs,grasslands and wetlands is expanding,with the boundary moving westward and towards high-altitude areas.Under the influence of climate change,the productivity,carbon sequestration,and soil conservation capacity of the ecosystem on the Tibetan Plateau have improved,and changes in water conservation have shown significant special heterogeneity.The profound impact of climate change on phenology,plant growth rate,distribution range and species interactions of animals and plants,as well as biodiversity,requires further observation and research.
