中文摘要:

河西走廊干旱区是我国西北地区重要的生态脆弱带，其水生态系统服务功能对于维系区域生态平衡、保障水资源安全和社会经济发展具有重要意义。以河西走廊为评估对象，在收集分析最新河西5市有关水资源利用与研究成果的基础上，参考区域水生态系统服务价值评估技术规范，核算了这一地区水生态系统服务功能价值，建立了水生态系统服务功能价值评估指标体系；进而采用市场价值法、影子价格法、替代成本法、机会成本法、旅行费用法等方法评估了河西走廊水生态系统服务功能价值。研究结果表明：河西地区水生态系统服务功能总价值为9 573. 53亿元，其中供给服务总价值55. 30亿元，调节服务总价值9 412. 03亿元，生态文化服务总价值160. 20亿元。期望研究成果为河西走廊水资源的合理调配和可持续利用提供科学依据。

英文摘要:

The Hexi Corridor, located in the arid region of Northwest China, constitutes a critical ecologically fragile zone. Its water ecosystem services are vital for maintaining regional ecological balance, ensuring water resource security, and supporting socio-economic development. Focusing on the Hexi Corridor as the study area, this research assessed the value of its water ecosystem services. Based on the collection and analysis of the latest data and research findings concerning water resource utilization from the five cities within the corridor, and referencing the technical specifications for regional aquatic ecosystem service value assessment, the value of aquatic ecosystem services in this region was quantified. An evaluation index system for water ecosystem services value was established. Methods including the market value approach, shadow price method, replacement cost method, opportunity cost method, and travel cost method were employed to assess the water ecosystem services value. The results indicate that the total value of aquatic ecosystem services in the Hexi region amounts to 957. 353 billion CNY （Chinese Yuan Renminbi）. Specifically, the total value of provisioning services is 5. 53 billion CNY, regulating services contribute 941. 203 billion CNY, and cultural services are valued at 16. 02 billion CNY. The findings are expected to provide a scientific basis for the rational allocation and sustainable utilization of water resources in the Hexi Corridor.
