生态系统服务权衡最新研究进展

Progress of research regarding the trade-offs of ecosystem services

  • 摘要: 生态系统服务权衡研究对协调生态环境保护和社会经济发展至关重要。为推动生态系统服务管理和提升人类福祉,本文以Web of Science核心合集(WOS)和中国科学引文数据库(CSCD)为数据源,运用文献计量分析法,系统梳理和总结生态系统服务权衡研究的学科知识基础、科学领域结构和热点变化等发展现状以及最新研究进展。研究表明:1)不同研究层面上,生态系统服务间的权衡关系受外部风险和人类需求、参数选取和服务提供者及区域差异性和不均衡性的影响。2)研究方法主要有基于关系识别和具体表征的权衡分析、权衡模拟和预测的模型量化分析和生态系统服务权衡管理优化的多准则分析3类。3)生态系统服务权衡关键驱动因子为城市化、生态工程和气候变化。基于此,我们认为把握生态系统服务权衡不同研究层面的关联特征、创新和优化生态系统服务权衡研究方法、准确甄别生态系统服务权衡关键驱动因子以及充分整合多维生态系统服务权衡资源搭建数据共享平台是未来研究的重点。

     

    Abstract: The extreme intensification of human activities and global climate change have exerted immense pressure on the ecological environment. According to the Millennium Ecosystem Services Assessment, approximately 60% of ecosystem services are in decline globally. Therefore, to better maintain ecological health, promote human well-being, and achieve more sustainability in harmonizing environmental protection and socio-economic development, there remains an urgent need to summarize recent studies on the trade-offs of ecosystem services. In this study, based on the Web of Science Core Collection Database (WOS) and the Chinese Science Citation Database (CSCD), CiteSpace was used to determine the current situation and analyze the latest research on ecosystem services trade-offs by choosing different techniques to create a co-citation cluster view of the citations, a knowledge map of the co-occurrence of subject structure, and a key word emergence map. The results showed that: 1) the trade-offs between ecosystem services are affected by external risks and human needs at the ecosystem level, parameter selection and service providers at the landscape level, and regional differences and heterogeneity at the regional level. 2) Research methods mainly include three categories: trade-off analysis based on relationship recognition and concrete characterization, a module-based quantitative analysis of trade-off simulation and prediction, and multi-criterion analysis toward the optimization of ecosystem service trade-off management. 3) Urbanization, ecological engineering, and climate change are three key drivers of the trade-offs associated with ecosystem services. Most of the trade-offs between supply services, regulation, and support services are caused by urbanization. Ecological engineering improves ecosystem regulation and support services, but reduces supply services to some extent. Global climate change increases external risks while decreasing ecosystem service provision, regulation, and support functions. Based on this analysis, understanding the associated characteristics of ecosystem service trade-offs at various research levels, modifying and innovating study methods, identifying the major factors, and finally, integrating resources to build a data-sharing platform for ecosystem service trade-offs should be the focus of future research.
