摘要
应澳大利亚联邦科学与工业研究组织(Commonwealth scientific and Industrial Research Organisation, CSIRO)邀请,2018年4月清华大学组织科技考察团赴澳大利亚墨累-达令河流域开展为期一周的科学考察。考察团从墨累河出海口逆流而上,通过学习交流、现场考察和访问农场等方式,与澳大利亚同行们进行了深入交流,对澳大利亚墨累-达令河流域的气候变化与水的影响与适应对策研究,尤其是陆面水文-气候、极端水文研究、水资源管理体系的最新动态,及其气候变化应对与减缓、极端水文事件风险管理等进一步了解。此次考察对认识多时空尺度的气候-陆面-水文相互作用机理及其对自然强迫和人类活动(含人为强迫和下垫面人类活动)的响应机制,揭示全球气候系统能量-水循环动态演变规律和极端水文事件变化成因,构建全球增暖背景下应对极端水文事件的风险管理体系,提出中国适应性对策具有重要的借鉴意义。
At the invitation of the Commonwealth Scienti?c and Industrial Research Organisation, a scienti?c research delegation organized by Tsinghua University went to the Murray Darling Basin in Australia for a one-week field excursion in April 2018.The delegation went upstream from the mouth of the Murray Darling River to Canberra, and conducted in-depth exchanges with Australian counterparts and farmers. The research status of hydrology-climate, risk management of extreme hydrological events, water management systems, and climate change mitigation are further understood. The results are bene?cial to understand the atmosphericland surface-hydrological interaction mechanism of multi-temporal scale and its impact on natural forcing and human activities, to uncover the response mechanism of forced and underlying human activities, to reveal the dynamic evolution of energy-water cycle and the causes of extreme hydrological events in the global climate system, to construct a risk management system for extreme hydrological events in the context of global warming, and to propose China's adaptive countermeasures.
