摘　　要：生态脆弱性评价是生态治理和修复的重要前提。柴达木盆地是对全球气候变化和人类活动干扰最为敏感的区域之一。通过SRP模型构建柴达木盆地生态脆弱性评价指标体系,基于地理信息技术和遥感技术,采用层次分析法,系统、定量地对柴达木盆地生态脆弱性进行评价。结果表明:1)柴达木盆地微度,轻度类型脆弱区面积为79326 km^(2),占区域总面积的29.28%;中度类型脆弱区面积为67044 km^(2),占区域总面积的24.74%;重度,极度类型脆弱区面积为124613 km^(2),占区域总面积的45.98%。2)柴达木盆地东中西部生态脆弱性表现为“低-中-高”的分布特征。3)柴达木盆地生态脆弱性呈现出强烈的空间正相关特征。Ecological vulnerability assessment is an important prerequisite for ecological management and restoration.The Qaidam Basin is one of the most sensitive regions to global climate change and human ac-tivities disturbance.In this paper,the ecological vulnerability evaluation index system of the Qaidam Basin is constructed by SRP model,and the ecological vulnerability of the Qaidam Basin is evaluated systemati-cally and quantitatively based on geographic information technology and remote sensing technology,using hierarchical analysis.The results show that:1)the area of the slight,mild type of vulnerable area in the Qa-idam Basin is 79,326 km^(2),accounting for 29.28%of the total area;the area of the moderate type of vulner-able area is 67,044 km^(2),accounting for 24.74%of the total area;the area of the severe,extreme type of vulnerable area is 124,613 km^(2),accounting for 45.98%of the total area.2)the ecological vulnerability in-dex of the Qaidam Basin gradually increases from the east to the center and the west.3)the ecological vul-nerability of the Qaidam Basin shows a strong positive spatial correlation.
