摘要
定量评估区域水安全是水安全问题诊断和科学决策的重要基础。为分析甘肃省水安全的时空变化特征,构建2个系统层、6个准则层、25个评价指标的指标体系,基于改进的层次分析法和熵权法的组合赋权法计算各指标权重,利用云模型综合评价了甘肃省14个市(州)2010、2015、2020年水安全状况。结果表明,2010、2015、2020年各市(州)水安全呈上升趋势,总体处于基本安全和比较安全等级;水资源短缺和水旱灾害为影响甘肃省水安全的主要制约因素,改善水资源条件、提高现代水管理水平为提升甘肃省水安全的重要措施。
Carrying out quantitative assessment of regional water security is an important basis for water security diagnosis and scientific decision-making. To analyze temporal-spatial characteristics of water security in Gansu Province, an index system of 2 system layers, 6 criteria layers and 25 evaluation indexes was constructed. Based on the combination weighting method of improved AHP and entropy weight method, the weight of each index was calculated. The water security status of 14 cities(states) in Gansu Province in 2010, 2015 and 2020 was comprehensively evaluated by cloud model. The results show that the water security of each city(state) is on the rise in 2010, 2015 and 2020, and it is generally in the basic and relatively security level. The shortage of water resources and flood and drought disasters are the main restrictive factors that affect the water security in Gansu Province. Improving water resources conditions and modern water management level are the important measures to improve the water security in Gansu Province.
