    基于服务簇的沱江流域生态系统服务权衡/协同关系演变

    Evolution of Ecosystem Service Trade-offs and Synergies in the Tuojiang River Basin Based on Ecosystem Service Bundles

    • 摘要: 明确流域生态系统服务簇的时空格局以及簇内生态系统服务动态权衡/协同关系对管理和维持流域生态系统结构与功能的稳定性和可持续性有重要意义。基于InVEST模型、土壤流失方程等方法估算2010、2015、2020年3期沱江流域生态系统服务, 并使用K-means聚类识别生态系统服务簇, 以服务簇视角衡量服务簇内部主要生态系统服务间动态权衡/协同关系, 讨论权衡/协同关系及服务簇的时空变化规律, 针对不同簇模式提出相应的分区管控建议。结果表明: (1)2010-2020年沱江流域各生态系统服务空间格局稳定, 生态系统服务变化各异。生境质量、产水、固碳服务总量上升, 粮食生产、水土保持服务总量下降。固碳、水土保持以及生境质量服务高值区表现为在北部及中北部集中分布, 产水服务量由南向北减小, 粮食生产服务高值区主要集中于流域中北部和南部耕地区, 文化娱乐服务高值区呈现出显著的城市及城市间网络状连接趋势。(2)根据聚类结果将流域划分为5种生态系统服务簇, 各簇存在时空异质性。粮食生产簇占比为72.9%, 以粮食生产、产水服务为主; 生态保育簇占比为15.2%, 以生境质量、固碳服务为主; 文化娱乐簇占比为6.9%, 以文化娱乐服务为主; 多功能耦合簇占比为4.4%, 以生境质量、固碳、水土保持服务为主; 水土保持簇占比为0.5%, 以水土保持服务为主。(3)宏观而言, 沱江流域整体权衡关系多于协同关系, 服务簇内部各服务协同关系多于权衡关系, 应因地制宜采取管控措施。不同生态系统服务簇内部各服务权衡/协同关系存在相似与差异性, 不同服务簇内各相同服务组合的权衡/协同关系强弱不同, 服务簇内部各服务协同关系多于权衡关系, 流域整体权衡关系多于协同关系。研究成果可为沱江流域区域未来生态系统管理与优化、生态文明建设及可持续性发展提供科学依据。

       

      Abstract: It is important to maintain the stability and sustainability of river basin ecosystems, which requires an understanding of the dynamics of ecosystem services bundles and the trade-off/synergistic relationships within them. In this study, ecosystem services in the Tuojiang River Basin were modelled using InVEST software and a soil loss equation for the years 2010, 2015 and 2020. Ecosystem service bundles were identified through K-means clustering. The dynamic trade-off/synergistic relationships among major ecosystem services within bundles were measured. These relationships and the dynamics of service bundles are discussed. Some regional management approaches for different bundle types are proposed. We found that: (1) the spatial pattern of ecosystem services changed slightly and the changes in each service are different from 2010 to 2020. Specifically, the ecosystem services of habitat quality, water production and carbon sequestration increased, whereas total food production and soil conservation area decreased. High service values in carbon sequestration, soil conservation, and habitat quality were concentrated in the northern and north-central regions of the basin. High service values in water production were concentrated in middle and lower reaches of the basin and decreased from south to north. High service values in food production were mainly concentrated in the central-north and southern cultivated regions of the basin. High service values in culture and entertainment were established in urban areas and had inter-city networked connections. (2) According to clustering analysis, the river basin can be divided into five ecosystem service bundles that have spatiotemporal heterogeneity. A food production bundle accounted for 72.9% of the river basin area, which was dominated by food production activities and water production services. An ecological conservation bundle accounted for 15.2% of the area and was dominated by biodiversity and carbon sequestration services. The culture and entertainment bundle accounted for 6.9% of the area and was dominated by cultural and entertainment services. A multi-functional coupling bundle accounted for 4.4% of the area and was dominated by biodiversity, carbon sequestration, and water and soil conservation services. A water and soil conservation bundle accounted for 0.5% of the area and was dominated by water and soil conservation activities. (3) Within service bundle, there were more synergistic relationships than trade-off ones. However, across the whole river basin, there were more trade-off relationships than synergistic ones. The trade-off and synergistic relationships among ecosystem services had certain similarities and differences across different bundles. The relationships between certain service combinations had different intensities in different bundles. The results provide a reference for ecosystem management and optimization, ecological civilization, and sustainable development of the Tuojiang River Basin.
