摘　　要：针对我国生态脆弱区生态保护修复问题,以青海湖流域为例,在生态系统服务重要性和生态敏感性基础上识别关键性生态空间,同时结合流域生态安全格局及典型生态问题,划定生态保护修复分区,并提出不同分区的修复策略。结果表明:青海湖流域内生态系统服务极重要区占流域总面积的63.2%,生态极敏感区占流域总面积的6.55%;青海湖流域的核心型生态空间面积为18746.72 km^(2),优先型生态空间面积为5324.26 km^(2),其共同构成的关键性生态空间占流域总面积的81.15%;根据流域上中下游、地形等实际自然地理特征,提出构建青海湖流域“一网四区”的生态安全格局,结合生态安全格局和关键性生态空间及典型生态问题,将青海湖流域划定为6个生态保护修复分区,并有针对性地提出生物多样性保护、构筑湿地生态系统网络和水土保持等工程措施。In view of the ecological protection and restoration in China's ecologically vulnerable areas,taking Qinghai Lake Basin as an example,key ecological spaces were identified by evaluating the importance of ecosystem services and ecological sensitivity.At the same time,ecological protection and restoration zones were delimited based on the ecological security pattern and typical ecological problems of the basin,and the restoration strategies for different zones were proposed.The results showed that:1)The area of extremely important ecosystem services in the basin accounted for about 63.2%of the total basin area,and the area of extremely sensitive ecological zones accounted for 6.55%of the total basin area.2)The area of core ecological space in Qinghai Lake Basin was 18746.72 km^(2)and the area of priority ecological space was 5324.26 km^(2),which together constituted the critical ecological space area accounting for 81.15%of the total area of the basin.3)According to the natural geographic features of the upper,middle and lower reaches of the basin and the topography,the ecological security pattern of the basin was constructed as"one network and four zones".Based on the ecological security pattern,key ecological space and typical ecological problems,Qinghai Lake Basin was divided into six ecological protection and restoration sub-zones,and engineering measures such as biodiversity protection,construction of wetland ecosystem network and soil and water conservation were put forward.
