摘要:
[目的]研究城市水资源的脆弱性,客观反映水资源的可持续发展能力,为建设可持续发展城市提供参考。[方法]本文把广东省21个行政市及佛山市顺德区水资源列为实证对象,从自然因素、人为因素、承载力因素3个角度建立评价指标体系;在熵权法计算影响权重的基础上利用线性加权求和法构建水资源脆弱性评价模型。[结果]广东省水资源脆弱性总体呈现较脆弱,深圳市水资源脆弱性呈现不脆弱,在22个研究对象中水资源脆弱性表现最稳定。[结论]根据广东省水资源脆弱性评价结果结合智慧城市中可持续发展的目标可知,由于产业结构、水资源利用效率较低等问题导致广东省水资源脆弱性较高,可以通过产业结构改革,建设智慧水务和利用科技水平提高水资源利用效率等方法来降低水资源脆弱性。

Abstract:
[Objective] To reserch the vulnerability of urban water resources, and reveal the ability of the sustainable development of urban water resources in order to provide reference for building sustainable cities.[Methods] This article listed the water resources of 21 administrative cities of Guangdong Province and Shunde District of Foshan City as empirical subjects. The evaluation index system was established from three perspectives including natural, human and bearing capacity factors. Based on the entropy weight method, the water resources vulnerability assessment model was constructed using the linear weighted summation method.[Results] Water resources in Guangdong Province were relatively vulnerable, and the water resources in Shenzhen City were not vulnerable. Among 22 research subjects, water resource vulnerability of Shenzhen City was most stable.[Conclusion] According to the results of water resources vulnerability assessment in Guangdong Province, and sustainable development of smart city, water resources vulnerability in Guangdong Province was high. The utilization of water resource can be improved through the reform of industrial structure, the construction of smart water affairs and the utilization of science and technology.
