摘要
采用熵权法确定亚洲—太平洋地区水安全评价指标体系中各指标的权重,评估亚洲—太平洋47个国家的水安全状况。国家综合水安全包括生活水安全、经济水安全、城市水安全、环境水安全和水灾害抗御力五个方面,权重比值约为34:19:14:22:11。其中,生活水安全的国家间差异最大,水灾害抗御力的国家间差异最小;经济水安全的区域整体状况最好,而水灾害抗御力的整体水平较不理想。综合水安全的评估结果显示,在国家层面,澳大利亚、新西兰、马来西亚和新加坡的水安全状况最佳,基里巴斯的水安全状况最令人担忧;在区域层面,东亚及太平洋地区的水安全状况较之南亚、东南亚和中西亚为佳;整体而言,亚洲—太平洋地区的整体水安全状况亟待改善。
In this study the entropy method was adopted to calculate the indicator weights of the water security indicator system and the water security status of the 47 countries in the Asia-Pacific region were then assessed.National water security consists of 5 dimensions—household water security, economic water security, urban water security, environmental water security, and resilience to water- related disasters. The regional disparity of household water security is most significant, while the minimum value of regional disparity is found in resilience to water- related disasters. Regional economic water security is relatively satisfactory in Asia- Pacific; however,compared to other dimensions, resilience to water- related disasters is less satisfactory. The assessment reveals the actual water security status of countries and the result indicates that Australia, New- Zealand, and Malaysia are the most favorable countries in terms of national water security, but Kiribati is the worst country; countries in East Asia and the Pacific are in a much better condition than those in South Asia, Southeast Asia, and CentralWest Asia. The overall water security situation in Asia and the Pacific region urgently needs improvement.
