摘要
青藏高原作为我国建设生态文明高地的重要区域,是我国乃至亚洲生态安全屏障的关键区域。本研究对中国知网(CNKI)数据库与Web of Science Core Collection(WoSCC)数据库中1999-2024年有关青藏高原生态安全领域的研究文献进行了CiteSpace可视化分析。结果表明:气候变化是影响青藏高原生态安全的核心因素,尤其是冰川退缩、冻土退化以及水文循环的变化,已成为加剧生态环境脆弱性的重要驱动因素;人类活动如放牧、城镇化及基础设施建设,进一步加剧了生态压力,特别是对生态系统结构和功能的干扰;气候变化与人类活动的叠加效应是目前青藏高原生态安全面临的主要挑战。在研究方法方面,青藏高原生态安全研究逐渐从定性描述向定量分析、模型模拟以及多学科交叉融合的方向发展,遥感技术、地理信息系统及大数据分析成为重要工具。深化人地耦合研究、推进生态补偿和流域协同治理以及提升基于多源数据的情景模拟与预测能力是该领域的重要研究热点。未来,还需要深化气候变化与生态系统响应的综合研究、推进制度创新与区域协同治理、加强跨学科合作与技术融合。
The Tibetan Plateau,a critical region for China's ecological civilization construction,serves as an essential ecological security barrier for both China and the broader Asian continent.This study employs CiteSpace to conduct a bibliometric analysis of research on ecological security in the Tibetan Plateau,utilizing literature from the China National Knowledge Infrastructure(CNKI)and the Web of Science Core Collection(WoSCC)databases spanning from 1999 to 2024.The findings indicate that climate change is the primary factor influencing ecological security in the Tibetan Plateau,with glacier retreat,permafrost degradation,and alterations in hydrological cycles emerging as significant drivers of the region's increasing ecological vulnerability.Human activities,including grazing,urbanization,and infrastructure development,further intensify ecological pressures,particularly by disrupting ecosystem structure and function.The combined effects of climate change and anthropogenic activities present the foremost challenges to the region's ecological security.In terms of research methodology,studies on ecological security in the Tibetan Plateau have evolved from qualitative assessments to quantitative analyses,model simulations,and interdisciplinary integration,with remote sensing,geographic information systems,and big data analysis becoming essential tools.Key research priorities in the field include advancing human-environment coupling studies,promoting ecological compensation and watershed-based collaborative governance,and enhancing scenario modeling and prediction capabilities using multi-source data.Looking ahead,there is a need to deepen the integrated study of climate change and ecosystem responses,foster institutional innovation and regional collaborative governance,and strengthen interdisciplinary cooperation and technological convergence.
