摘　　要：生态文明建设背景下,明确流域生态系统服务及其相互作用关系的演变和驱动机制,对流域国土空间生态保护与可持续发展具有重要意义。以梁子湖流域为例,基于FLUS模型、Pearson相关性分析、自组织映射、地理探测器等方法识别流域2010—2030年土地利用变化情况,揭示流域生态系统服务及其相互作用关系的时空演变规律与驱动因素,并提出基于生态系统服务簇的流域生态空间保护的工作框架。结果发现:(1)2010—2030年,流域土地利用变化情况显著,整体表现为耕地和水体面积减少、林地和建设用地面积增加。(2)3种模拟情景中,仅生态保护情景时流域生态系统服务价值上升,其余均呈现不同程度的下降趋势。(3)流域各项生态系统服务之间存在权衡与协同关系,且协同关系占据主导地位。(4)流域共识别出6种生态系统服务簇,其中以食物生产为主导功能的服务簇面积占比最大;服务簇的识别结果与实际土地利用类型较为一致,但同类用地仍可提供多个具有不同主导服务功能的服务簇。(5)流域生态系统服务簇的分异是自然环境、社会经济与景观格局共同作用的结果,优化景观格局能一定程度上保护流域主导服务功能的稳定。The rapid surge in urbanization has given rise to phenomena such as urban expansion,population congestion,and environmental degradation,thereby posing significant threats to the ecological integrity of watersheds.In the pursuit of building an ecological civilization,considerable emphasis has been placed on fostering a harmonious relationship between human beings and nature,and advancing high-quality development with a robust level of protection.Ecosystem services(ES)and ecosystem service bundles(ES bundles)are of great significance for the conservation and development of ecological spaces in watersheds in the face of rapid urbanization.Clarification of the spatio-temporal changes and driving mechanisms of watershed ecosystem services and their interactions is crucial to the ecological protection and sustainable development of watershed territorial space under the construction of an ecological civilization.Taking the Liangzi Lake Basin as an example,based on the FLUS model,Pearson correlation analysis,Self-Organizing Mapping,Geo-Detector,and other methods,the land use changes in the basin were identified from 2010 to 2030.It reveals the spatio-temporal evolution patterns and driving factors of ecosystem services and their interactions,putting forward the work of basin ecological spatial protection based on ecosystem service bundles.The results show that:(1)From 2010 to 2030,the land use in the basin changed significantly,with the overall performance of decreased cropland and water areas and increased forest and impervious areas.(2)Based on three modeling scenarios,only the ecosystem service value of the basin increased under the ecological protection scenario,whereas the others decreased to varying degrees.(3)Trade-offs and synergistic relationships existed among ecosystem services in the basin,with the synergistic relationship being the most prominent.(4)The basin was classified into six types of ecosystem service bundles,with the service bundle dominated by food production accounting for the largest proportion o
