基于F-H方法的冲突局势稳定性分析方法及其应用

冲突是一类普遍的社会现象,基于元对策的F H冲突分析方法已经在水资源冲突管理领域得到了广泛的应用。在深入分析F H方法原理的基础上,提出了一种考虑决策者对冲突问题预见能力的冲突局势稳定性分析方法,寻求冲突问题的均衡解。在局势稳定性分析过程中,当局中人基于个人预见水平不存在单方改进某可行局势的动机时,该局势对此局中人而言是稳定的。当全体局中人都认为某可行局势是稳定的,则此局势称为冲突问题的均衡点。最后,该方法被运用到湖北省宜昌市黄柏河流域水资源冲突问题中,模拟结果表明宜昌市水电局同时采取“激励合作”“强化管理”、东风渠灌区管理局“增加引水”、黄柏河流域管理局“追求效益”是最稳定的一种策略组合。提出的冲突局势稳定性分析为寻求冲突均衡提供了一种可行方法。     

The drivers of risk to water security in Shanghai

Big cities are often said to have big water problems, and Shanghai is no exception. In this paper, we examine and compare the influence of the major factors that give rise to the risk of water insecurity in Shanghai. There is an extensive and diverse literature on these issues, dealt with in isolation, and here, we provide a synthesis of the literature, together with our own assessments and calculations, to assess what are the risks to Shanghai’s water supply and what is our degree of confidence in this assessment. We describe the systems that supply water to the city, and past and future changes in the systems, including changes in the glaciers that supply some water to the river, changes in climate, changes in land use, the construction of dams, and water diversions. We show how, at the same time as Shanghai is increasing its dependence on the Yangtze river, water diversions and sea level rise are increasing the risk that this water will be too saline to consume at certain times of the year. This analysis suggests that most of the major drivers of the risk to water security in Shanghai are within the power of environmental managers to control.
