中文摘要: 青藏高原是地球第三极、是亚洲水塔、是我国重要的生态安全屏障。2017年启动的第二次青藏高原综合科学考察研究（简称“第二次青藏科考”）国家专项，定位于环境变化与影响及其对策，围绕青藏高原地球系统变化及其影响这一关键科学问题，聚焦西风—季风协同作用、亚洲水塔变化与影响、生态系统与生物多样性变化、人类活动对环境影响与适应、灾害风险与应对等问题，重点考察研究过去50年来环境变化的过程与机制及其对人类社会的影响。目前，第二次青藏科考在亚洲水塔失衡、青藏高原固碳功能与变化、青藏高原生态系统和生物多样性变化、川藏铁路沿线灾害应对和生物多样性保护、青藏高原矿产资源远景评估、青藏高原人类适应历史与绿色发展建议等方面取得重大进展，为青藏高原生态文明高地建设和区域可持续发展作出了贡献。
Abstract:The Tibetan Plateau is known as the Third Pole, the Asian Water Tower, and China's important ecological security buffer. The Second Tibetan Plateau Scientific Expedition and Research (STEP) program, launched in 2017, is oriented at environmental changes and impacts as well as adaptation. Focusing on the key scientific question of Earth system changes and their impacts on the Tibetan Plateau and dealing with the key issues including westerly-monsoon interactions, Asian Water Tower changes and impacts, changes in ecosystems and biodiversity, effects and adaptation of human activities on the environment, disaster risk adaptation and mitigation, the STEP is studying the process and mechanism of environmental changes in the past 50 years and their impact on human society. At present, the STEP has made significant progress on the imbalance of Asian Water Tower, the function and changes of carbon sequestration, the changes in ecosystem and biodiversity, disaster management and biodiversity protection along the Sichuan-Tibet Railway, the assessment of mineral and clean resources,the history of human adaptation and green development. These progress contributes to building ecological civilization highland and to regional sustainable development.
