摘要
水资源、能源和粮食是生产生活的基本要素。将3者视为一个相互依赖的系统,水资源-能源-粮食系统的耦合协调发展是区域可持续发展的重要基础。以辽宁省为研究对象,通过构建耦合协调度评价指标体系,采用熵值法赋权并引入耦合协调度模型及计算方法,对2006-2015年水资源-能源-粮食系统的耦合协调关系及其时序演化特征进行了实证分析。研究结果表明:辽宁省2006-2015年水资源-能源-粮食系统的整体协调发展能力在波动中不断增长,耦合协调度大致经历了过渡、基本协调2个发展阶段和勉强协调、初级协调、中级协调3个发展类型,且持续提升的趋势非常明显,但尚未跨入高度协调发展阶段,还有很大的提升空间。
Water, energy and food are the basic elements of production and life, they constitute an interdependent system, The coordinated development of Water-energy-food system is an important foundation for regional sustainable development. Taking Liaoning Province as the research object, the evaluation index system is established, the entropy method is used to calculate the weight of each index, and then the coupling and coordination degree of Water-energy-food system is evaluated quantitatively, its coupled coordination evolutionary characteristics from 2006 to 2015 are analyzed. The results show that, the coordinated development level of Water-energy-food system in Liaoning Province from 2006 to 2015 is growing in the fluctuation. The coupling coordination degree has undergone a transition stage and a basic coordination stage, experienced reluctance coordination, primary coordination and intermediate coordination development types. The trend towards continuous enhancement is significant, but it has not yet entered a highly coordinated development stage, there is a lot of room for improvement.
