摘　　要：基于生态系统服务功能对流域生态环境进行功能分区是流域生态环境保护与修复的重要基础.本研究使用InVEST模型,对大清河-白洋淀流域2010、2015及2018年的生境质量、碳储量及土壤侵蚀等生态系统服务功能进行评价.结果表明:2010—2015年流域生态环境相对稳定;2015—2018年生境质量提升,土壤侵蚀缓解,但碳储量有所下降;流域内72.91%的区域处于中度敏感状态,3.99%的区域处于高度敏感状态,生态功能现状不容乐观.在此基础上叠加分析各子功能评价地图,将研究区划分为3个一级功能区及7个二级功能区,旨在今后对各功能区采取针对性的利用和管理策略,以维持和改善生境质量,为区域可持续发展提供支撑.Ecological regionalization based on ecosystem service assessment is an important basis for ecological restoration and environmental protection at the basin scale. In this research,the InVEST model was used to assess ecosystem services,covering habitat quality,carbon storage and soil conservation in the Daqing River-Baiyangdian Lake Basin of 2010,2015 and 2018. The results showed that:the ecosystem service functions were stable from 2010 to 2015;the habitat quality and soil conservation functions were improved with carbon storage function decreased from 2015 to 2018;72.91% of the basin was moderately sensitive,and 3.99% was highly sensitive. As the results indicated that,it was not optimistic for the current situation of ecosystem service functions in Daqing River-Baiyangdian Lake Basin. Based on the overlay analysis of the corresponding assessment maps,the Daqing River-Baiyangdian Lake Basin was divided into three level I eco-regions and seven level II eco-regions. This research can provide scientific support for making utilization and management strategies to maintain and improve basin habitat quality for regional sustainable development.
