第二次青藏科考:青藏高原还能再养活1307万人

Core Insights - The second comprehensive assessment of the Qinghai-Tibet Plateau indicates a potential carrying capacity of approximately 26.2 million residents, allowing for an increase of about 13.07 million from the current population of 13.13 million, highlighting significant development potential [1] - The research focuses on addressing major national strategic needs and has produced over 140 decision-making reports to support sustainable development in the region [1][2] Group 1: Research Achievements - The second Qinghai-Tibet scientific expedition has established a comprehensive observation network covering 19 key areas, integrating "air-space-ground" monitoring to facilitate a closed-loop transformation from science to policy to practice [2] - The urbanization rate of the Qinghai-Tibet Plateau is approximately 48%, with a potential increase of 9.67%, leading to a proposed urban development model based on "small gathering and large dispersal" [4] - The expedition has identified 10 differentiated green development models to support unique urbanization in the plateau [4] Group 2: Disaster Prevention and Ecological Protection - A multi-dimensional technological support system has been established, successfully issuing six warnings for ice avalanche disasters and optimizing transportation routes to avoid over 97% of mountain hazards [5] - The expedition has assessed the carbon sink capacity of the Qinghai-Tibet Plateau, estimating an annual carbon sink of 120 to 140 million tons, significantly exceeding local carbon emissions of about 55 million tons [5] Group 3: Biodiversity and Resource Exploration - The expedition has published over 3,000 new species, including 388 plants and 205 animals, and has created the largest glacier virus and bacteria gene collection globally [6] - In resource exploration, the expedition has identified 40 solid mineral prospecting areas and 110 brine lithium prospecting areas, alleviating reliance on foreign resources [7][8] Group 4: Environmental Transformation and Future Directions - The Qinghai-Tibet Plateau is undergoing a "third environmental transformation," characterized by global warming and human activities, with an increase in temperature at a rate of 0.37 degrees Celsius every decade, double the global average [9][10] - Future research will focus on green and livable development under the new environmental transformation, addressing water-carbon-health interactions and ensuring the safety of strategic mineral and biological resources [11][13]
中国科学家:青藏高原隆升影响全球热量分配

Core Viewpoint - Chinese scientists propose the "triple polar linkage" hypothesis, suggesting that the uplift of the Tibetan Plateau significantly influenced global heat distribution and climate change processes over millions of years [1][3]. Group 1: Tibetan Plateau Uplift - The Tibetan Plateau's northern region experienced rapid uplift between 12 million and 8 million years ago, altering atmospheric circulation and carbon cycling, which played a crucial role in global climate change [1][3]. - The second Tibetan scientific expedition detailed the uplift process of the Tibetan Plateau, highlighting that the central and southern parts rose rapidly from 40 million to 30 million years ago, while the northern and northeastern regions began significant uplift only from 12 million years ago [3][4]. Group 2: Climate and Ecological Impact - The uplift of the Tibetan Plateau has been linked to significant ecological changes, including the evolution of modern African savanna fauna originating from the northeastern edge of the plateau around 8 million years ago, and Arctic fauna tracing back to the plateau around 6 million years ago [3][4]. - The strong uplift in the northern Tibetan Plateau has driven significant aridification in inland Asia and global cooling, leading to a transformation of ecosystems from forests to deserts and salt lakes [4]. Group 3: Global Climate Dynamics - The uplift enhances the frozen zone, erosion, and dust nutrient transport, which boosts Pacific biological activity and organic carbon burial, contributing to global cooling and polar ice cap expansion [4]. - The northern uplift of the Tibetan Plateau is synchronized with the development of the Arctic ice cap, strengthening of westerlies and winter monsoons, and significant aridification in Asia, establishing the "triple polar linkage" [4]. Group 4: Future Research Directions - Future work aims to accurately reconstruct the uplift process and validate the "triple polar linkage" hypothesis through numerical simulations, which is crucial for understanding Earth's system responses in the context of current global warming [4].
