摘要: 阐明多种生态系统服务之间的关系及相互作用机制可有效提高生态系统可持续供给能力。采用InVEST模型估算了南宁市6种典型生态系统服务,运用双变量Moran's I指数探讨生态系统服务间权衡与协同关系,采用主成分因子分析和聚类分析识别出不同生态系统服务簇。结果表明:(1)南宁市6种典型生态系统服务格局呈现显著空间异质特征,除产水量以外,其余生态系统服务均呈郊区高、城区低的分布格局;(2)支持服务与调节服务呈现协同关系,供给服务与其他服务之间既有协同关系也有权衡关系;(3)主成分1和3反映生态系统服务受共同驱动因子影响,主成分2反映生态系统服务的相互抑制作用;(4)根据聚类分析结果,可将南宁市分为5类生态系统服务簇,分别为山地生态均衡区、森林生态保育区、城市生态脆弱区、丘陵产量区和河谷水土流失区。研究成果可为南宁市土地利用配置优化和生态健康可持续发展提供科学依据。

Abstract: Clarifying the relationship and interaction mechanisms of multiple ecosystem services can effectively improve the sustainable supply capacity of ecosystems. In this paper, 6 typical ecosystem services of Nanning City were estimated by InVEST model, the ecological service trade-off and synergy were analyzed by Moran's I index, and the different ecosystem service clusters were recognized by principal component factor analysis and clustering method. The results show that: (1) The patterns of 6 typical ecosystem services in Nanning present significant spatial heterogeneity and is high in suburban area but low in urban area, except for water yield. (2) There is synergy relationship between support and adjustment services, but both synergy and trade-off relationship are existing between supply and other services. (3) The ecosystem services are affected by common driving factors revealed by principal component factor 1 and 3, and its mutual inhibition are represented by principal component factor 2. (4) The following 5 typical ecosystem service clusters were discovered in Nanning by employing cluster analysis: the mountain ecological balance area, forest ecological conservation area, urban ecological fragile area, hilly cultivated area, and valley cultivated area. This research results can provide scientific basis for the land use optimization and the ecological health and sustainable development in Nanning City.
