Based on InVEST model, recreational opportunity spectrum, factor analysis, cold and hot spot analysis, SOFM neural network, relief degree of land surface (RDLS) methods, we evalua-ted six kinds of ecosystem service in Fuzhou City and analyzed the trade-offs and synergies among them, with the aim to clarify the dominant services and the spatial pattern of service bundles in different topographical regions. The results showed substantial spatial heterogeneity in different ecosystem services of Fuzhou City. Water yield, carbon sequestration, habitat quality, and recreational opportunities were totally high, whereas the supply of agricultural products and soil and water conservation were low and substantial differences. The interaction between water yield and cultural servi-ces were synergies, but trade-offs occurred among regulating service, supporting service and agricultural products service. There were spatial aggregations for both trade-offs and synergies. Ecosystem service bundles could be divided into suburban recreation bundle, water conservation bundle, agricultural products bundle, urban life bundle, and forest ecological conservation bundle. The composition of service bundles clusters was different under different RDLS, with obvious spatial heterogeneity.
基于 InVEST 模型、娱乐机会谱、因子分析、冷热点分析、自组织特征映射神经网络、地表 Relief 度（RDLS）方法，我们评估了福州市的六种生态系统服务，并分析了它们之间的权衡与协同关系，旨在阐明不同地形区域的主导服务和服务束的空间格局。结果表明，福州市的不同生态系统服务存在显著的空间异质性。产水量、碳固存、生境质量和娱乐机会总量较高，而农产品供应和水土保持则较低且差异较大。产水量与文化服务之间存在协同作用，但调节服务、支持服务和农产品服务之间存在权衡关系。权衡和协同作用都存在空间聚集。生态系统服务束可分为郊区娱乐束、保水束、农产品束、城市生活束和森林生态保护束。在不同的 RDLS 下，服务束集群的组成不同，具有明显的空间异质性。
