摘　　要：生态系统服务间的相互作用及时空特征是维护人类福祉和实现区域可持续发展的关键。笔者以小滦河流域为研究对象,基于InVEST模型、修正版通用土壤流失方程模型和RDA分析,系统评估流域4种重要的生态系统服务,识别生态系统服务的权衡/协同关系及其驱动因素。结果表明:1)林地、草地的生境质量最高,林地的土壤保持、水源涵养服务优势明显,耕地水质净化服务供给能力较强。2)2000—2020年小滦河流域生境质量、水源涵养与水质净化呈增强趋势,土壤保持与水质净化服务由协同向权衡关系转变,与生境质量服务则表现为逐渐增强的协同关系。3)生态系统服务受多因子共同影响。降水、NDVI、林地比例对水源涵养、土壤保持、生境质量服务表现为正向影响,对水质净化服务表现为负向影响。小滦河流域应全面考虑生态系统服务和经济发展的情况,依据实际不断调整土地利用规划。研究结果可为当地制定合理的生态系统管理措施提供科学指导。[Background]The interactions and spatiotemporal and characteristics of ecosystem services are crucial for maintaining human well-being and achieving regional sustainable development.[Methods]Based on InVEST model,the revised universal soil loss equation(RUSLE)and RDA analysis,this paper systematically evaluated four important ecosystem services in the Xiaoluan River Basin,and identified the trade-offs/synergies of ecosystem services and their driving factors.[Results]1)Forest land and grassland had the highest habitat quality,with forest land showing significant advantages in soil conservation and water retention services,while cultivated land having a strong capacity for water purification services.2)From^(2)000 to 2020,the habitat quality,water retention and water purification in the Xiaoluan River Basin showed an increasing trend,and the relationship between soil conservation and water purification services changed from a synergistic relationship to a tradeoff relationship,while the relationship between soil conservation and water purification services showed a gradually enhanced synergistic relationship.3)Ecosystem services are influenced by multiple factors.Precipitation,NDVI and forest land proportion have positive effects on water retention,soil conservation and habitat quality services,but negative effects on water purification services.[Conclusions]The Xiaoluan River Basin should comprehensively consider the situation of ecosystem services and economic development,and continuously adjust the land use planning according to the actual situation.The results provide scientific guidance for formulating reasonable ecosystem management measures locally.
