全球首次系统评估城市爬坡对生物多样性影响

Core Insights - The research led by Professor Shi Kaifang from Anhui Normal University represents the first systematic assessment of the impact of urban slope development on natural habitat loss and endangered species over the past 20 years, published in the journal "Nature: Urban" [1][2] Group 1: Urbanization and Biodiversity - The global urban slope area increased by 11.65 million hectares from 2000 to 2020, with 35% of this area located in biodiversity hotspots, which constitute only 2.4% of the global land area [2] - This urban expansion has resulted in the loss of 6.73 million hectares of natural habitat, affecting over 70% of endangered vertebrate species [2] Group 2: Future Projections and Policy Implications - Based on current trends and model predictions, by 2050, 53 countries may struggle to meet moderate biodiversity protection goals, and 69% of biodiversity hotspots may fail to achieve set conservation milestones [2] - The research aligns with the urgent needs of the United Nations Sustainable Development Goals and the "Kunming-Montreal Global Biodiversity Framework," providing solid data support for land planning and ecological protection policy formulation [2]
