黄河流域粮食与能源水足迹压力与绿色发展脱钩关系研究

A Study on the Decoupling Relationship Between Grain and Energy Water Footprint Pressure and Green Development in the Yellow River Basin

黄河流域作为我国粮食与能源的主要产出地区,水资源的缺乏对其可持续发展构成了巨大威胁。为探究黄河流域水资源与绿色发展的关系,通过测算2011-2016年黄河流域粮食与能源水足迹,揭示虚拟水流动对水资源压力影响,并根据"五大发展理念"构建绿色发展指数,最后通过Tapio脱钩模型探究水资源压力与绿色发展的关系。结果表明:(1)黄河流域粮食和能源水足迹的空间差异性较大,山东和四川粮食和能源水足迹最高;(2)黄河流域多数省份存在缺水压力,宁夏达到极端缺水程度;(3)全流域绿色发展指数基本呈现逐年上升的趋势,且与水足迹压力指数的脱钩状态随时间变化有所改善。研究结果对黄河流域生态保护和高质量发展具有一定的理论意义。

The Yellow River Basin,as a main food and energy base in China,is suffering a potential threat to its sustainable development due to the lack of water resources.To investigate the linkage between water resources and the green development in the study area,in this study,the food water footprint(FWF)and energy water footprint(EWF)from 2011 to 2016 was measured to reveal the effect of virtual water flow on water stress.A green development index was also constructed based on the understanding of"five concepts of development".In addition,the Tapio decoupling model was conducted to explore the relationship between water resources stress and the sustainable development of the social economy.The results showed that:(1)The spatial difference of grain and energy water footprints was large in the Yellow River Basin,and the highest water footprints were found in Shandong and Sichuan.(2)The pressure of water shortage exists in most provinces of the Yellow River basin,and Ningxia is extremely short of water.(3)The green development index of the whole basin basically showed an increasing trend year by year,and the decoupling state from the water footprint pressure index improved with time.The results of this study have some theoretical significance for ecological protection and high-quality development of the Yellow River Basin.
