Abstract

Ecosystem services play an essential role as intermediaries, linking natural ecosystem resources to socio-economic demands. Understanding their impact on ecological well-being is pivotal for ensuring regional environmental security and promoting sustainable societal and economic development. However, there is insufficient research on the relationship between the two. Accordingly, this study explores the evolutionary relationship between ecological health and ecosystem services by constructing an evaluation system. Regression analysis is used to explore the spatial relationship between ecosystem services and ecological health, providing a reference for maintaining the balance between ecological supply and ecological health. The results show that from 1980 to 2020, an overall improvement was observed in the eco-health index of the Yangtze River Economic Belt's. This improvement was notably marked by substantial growth in the eco-vitality index alongside consistent maintenance of the spatial distribution within the eco-organization index. With regard to distributions of specific ecosystem services, dispersed occurrences characterized areas with high water production and crop yield levels; however, within forested regions, attributes for habitat quality preservation, water purification, soil retention and carbon sequestration were predominant. In the impact of ecosystem services on ecological health, food production held sway over less-developed areas, while soil conservation, water supply and habitat quality exerted greater influence over more-developed regions. This study regards ecosystem services as a bridge connecting humans and the environment not only providing a material basis for society but also reflecting the status of ecological health.

生态系统服务功能如何影响生态健康?来自中国长江经济带的证据。
生态系统服务发挥着重要的中介作用,将自然生态系统资源与社会经济需求联系起来。了解生态系统服务对生态福祉的影响对于确保区域环境安全、促进社会和经济的可持续发展至关重要。然而,目前对二者之间关系的研究尚不充分。因此,本研究通过构建一个评价体系来探索生态健康与生态系统服务之间的演变关系。通过回归分析,探讨生态系统服务与生态健康之间的空间关系,为维持生态供给与生态健康之间的平衡提供参考。结果表明,从 1980 年到 2020 年,长江经济带的生态健康指数出现了整体改善。这种改善的显著特点是生态活力指数的大幅增长和生态组织指数空间分布的持续保持。在具体生态系统服务的分布方面,高产水量和高作物产量地区的分布较为分散;而在森林地区,生境质量保护、水质净化、土壤保持和碳封存属性则占主导地位。在生态系统服务对生态健康的影响方面,粮食生产在欠发达地区占据主导地位,而土壤保持、水供应和栖息地质量则对较发达地区产生更大影响。本研究认为,生态系统服务是连接人类与环境的桥梁,不仅为社会提供物质基础,也反映了生态健康状况。
