长汀县生态系统服务权衡与协同关系

Trade-offs and synergies among ecosystem services in Changting County

  • 摘要: 以长汀县为研究区,采用当量因子法核算2010—2020年的生态系统服务价值,使用Pearson相关性分析方法和双变量自相关方法探讨生态系统间的权衡与协同关系,并借助自组织映射网络方法识别不同的生态系统服务簇.结果表明:2010—2020年长汀县生态系统服务价值在数量上呈现上升趋势,在空间上呈现“四周高、中心低”的环状分布特征;协同关系是长汀县生态系统服务的主导关系,主要分布在生态系统服务价值高的区域,权衡关系主要分布在生态系统服务价值低的区域;根据聚类结果和生态系统的主导服务功能将长汀县分为水源涵养簇、服务枯竭簇、生态调节簇和生产生态簇.研究结果可为长汀县生态系统服务可持续发展提供科学依据.

     

    Abstract: In the report, the equivalent factor method was used to determine the ecosystem services value of Changting County from 2010 to 2020. The Pearson correlation analysis and the bivariate autocorrelation were performed to elucidate the Trade-offs and synergy among ecosystem services. The self-organizing mapping method was used to identify the ecosystem service bundles. The results showed that the total increase of the value is 1.677 billion yuan from 2010 to 2020. The spatial distribution exhibited a ring-like pattern with elevated values in the periphery and diminished values at the center. The synergistic relationship was dominant relation, and which located primarily in areas with high ecosystem service value. The trade-off relationship prevailed in areas with low ecosystem service value. Based on the above data, the water conservation bundles, service depletion bundles, ecological regulating bundles, and production ecological bundles were identified. Our findings suggested the development in Changting County was sustainable.
