摘要
为了评价水资源短缺风险系数,在探讨风险评价理论方法的基础上,构建了水资源风险短缺评价指标体系,采用主成分分析法,从时间和空间两个方面较系统地分析评价了襄阳市水资源短缺的原因、影响因素及变动趋势。结果表明:襄阳市水资源短缺现象日益严峻,8个行政分区中襄阳市城区、襄州区、枣阳市、宜城市、老河口市等5个出现水资源严重短缺状况,这一结论与多指标综合评价结果具有较好的一致性,经验证方法可行、结论可靠。
To assess the risk of water shortage in Xiangyang City, a water shortage risk assessment indexsystem was constructed using the principal component analysis based on the risk assessment theory. Thereason of water shortage, influencing factors and changing tendency were analyzed. The results showed thatwater shortage risk in Xiangyang was increasingly serious, the urban areas of Xiangyang, Xiangzhou District,Zaoyang City, Yicheng City, Laohekou City were seriously short of water resource, which was consistent withthe results obtained from the principal component analysis. Therefore, the method using in this study isfeasible and can provide a reliable conclusion.
