| 摘 要： | 干旱/半干旱区气候变化研究一直是广泛关注的前沿科学问题,尤其是气候干湿变化规律及未来的发展趋势。过去大量的研究揭示了全球不同干旱/半干旱区的干湿变化事实和机理,取得了一系列重要进展,IPCC第6次评估报告明确指出未来全球干旱化将加剧,但也存在诸多问题没有得到一致的认识。本文将对全球变暖背景下有关干旱/半干旱区年代尺度干湿变化,特别是年代尺度干旱研究进行梳理,系统评述当前相关研究的现状并提出干旱/半干旱区研究所面临的关键科学问题。

| Abstract: | The investigation of climate change in arid and semiarid regions has long been a prominent scientific issue of extensive interest,particularly concerning the patterns and future trends of dry and wet climatic variations.Previous research has made significant advancements in unraveling the facts and mechanisms underlying these climatic changes across diverse arid and semiarid regions worldwide.Although the 6th IPCC evaluation report indicates a projected exacerbation of global aridity trends in the future,several contentious issues persist.This paper provides a comprehensive review of studies focusing on interdecadal changes in dry and wet conditions,particularly interdecadal drought,in arid and semiarid regions within the context of global warming.The current state of related research is systematically analyzed,and key scientific challenges faced by arid and semiarid region studies are identified. |
