【摘要】：针对传统水资源承载力研究中评价标准比较单一、评价结果相对简化等问题,提出了基于水资源系统健康的水资源承载力理念,建立了与之相应的区域水资源承载力评价的指标体系;吸取层次分析法蕴含决策经验意见的功能和离差最大化法反映客观标准的优点,构建了一种组合赋权法;依照属性识别理论的置信准则和评分准则建立基于组合权重的集对分析评价模型,并对山西省大同市水资源承载力进行了评价。结果表明:2005年-2012年间,大同市水资源承载力指数在0.499~0.728之间,随着大同市节水型城市建设的推进和绿色经济发展的转变,水资源承载力水平在逐年增强;但水资源系统长期处于亚健康状态,应加大水资源管理、水环境保护及水污染控制的力度,以改善未来水资源系统的健康状态。
[Abstract]:Aiming at the problems of single evaluation standard and relatively simplified evaluation result in the traditional research of water resources carrying capacity, the concept of water resources carrying capacity based on the health of water resources system is put forward. The corresponding index system of regional water resources carrying capacity evaluation is established, and a combined weighting method is constructed by absorbing the function of AHP which contains the opinions of decision-making experience and the advantage of maximization of deviation to reflect objective criteria. According to the confidence criterion and scoring criterion of attribute recognition theory, a set pair analysis and evaluation model based on combination weight is established, and the water resources carrying capacity of Datong City in Shanxi Province is evaluated. The results show that: from 2005 to 2012, the water resources carrying capacity of Datong City, Shanxi Province, was evaluated. The water resources carrying capacity index of Datong city is between 0.499 and 0.728. With the development of water-saving city and the change of green economy, the level of water resources carrying capacity is increasing year by year, but the water resources system is in sub-healthy state for a long time. Water resources management, water environment protection and water pollution control should be strengthened in order to improve the health of water resources system in the future.
