| 摘 要： | 为了客观评价贵阳市水资源脆弱性,结合相关利益机构及专家的建议,从暴露性、敏感性和适应能力3个方面入手,构建水资源脆弱性评价指标体系,在GIS技术支持下,利用层次分析法(AHP)对2000—2015年贵阳市水资源脆弱性进行评价。结果表明:贵阳市水资源脆弱性空间差异比较显著,水资源脆弱性增强和变弱并存,整体表现出由“中南部高且周边低”到“北弱南强”之态势;云岩区、南明区、白云区、乌当区、观山湖区和花溪区6个区水资源脆弱性增强明显,其中增强最为显著的是观山湖区、花溪区和乌当区,清镇市、修文县、息烽县和开阳县4个县(市)则以脆弱性减弱为主。研究成果可为贵阳市社会经济持续健康发展以及水资源合理利用提供参考依据。

| Abstract: | The vulnerability of water resources in Guiyang City in 2000-2015 was evaluated using Analytic Hierarchy Process (AHP) in GIS platform. An index system in aspects of exposure, sensitivity, and adaptability for the evaluation was established.Research findings suggest that the vulnerability of water resources in Guiyang City differed remarkably in spatial scale, with vulnerability intensifying and also weakening coexisted. From 2000 to 2015, the vulnerability developed from being high in the middle and south and low in surrounding areas towards low in the north while high in the south. In Yunyan district, Nanming district, Baiyun district, Wudang district, Guanshan Lake district and Huaxi district,the vulnerability of water resources has intensified evidently, among which Guanshan Lake district, Huaxi district and Wudang district witnessed the most remarkable changes. In Qingzhen city, Xiuwen county, Xifeng county, and Kaiyang county, the vulnerability of water resources mostly weakened. The results offer reference for the sustainable and healthy development of social economy and the rational utilization of water resources in Guiyang. |
