资源高强度流动区水、能源和粮食耦合协调发展研究——以京津冀地区为例
|
摘要
随着社会经济和人口的增长,各地区尤其是资源高强度流动区面临着越来越大的水资源、能源和粮食压力。为缓解地区内的资源压力,需要综合了解WEF系统之间的协调发展状况,以便更好地发挥资源间的协同作用,提高资源利用效率,实现WEF系统的安全及社会的可持续发展。通过构建WEF系统的综合评价指标体系,运用熵值法确定权重,综合评价了京津冀地区WEF系统的发展水平,并测算了三个系统间的耦合协调发展程度。结果表明,京津冀地区的WEF系统综合评价水平呈逐年上升趋势,其耦合协调度历经勉强协调、初级协调和中级协调三种类型向良好协调类型演进,总体上升空间较大。建议应针对地区情况,提高滞后系统的发展水平,加强跨部门合作,以实现WEF系统的资源安全及持续协调发展。
With the growth of economy and population, water, energy, and food in all areas, especially in areas with high resource intensity, are facing increasing pressure. In order to alleviate the resource pressure in the region, it is necessary to understand the coordinated development between WEF systems, so as to better play the synergy between resources, improve the efficiency of resource utilization, and realize the security of WEF systems and the sustainable development of society. This paper constructs the WEF system's comprehensive evaluation index system, determines the weights through the entropy method, comprehensively evaluates the development level of the WEF system in Beijing, Tianjin and Hebei, and measures the coupling and coordinated development of the three systems. The results show that the comprehensive evaluation level of the WEF system in the Beijing,Tianjin and Hebei has been increasing year after year. The coupling coordination degree has undergone three types of reluctant coordination, primary coordination, and intermediate coordination to evolve into good coordination types, and the overall rise space is relatively large. We should improve the development level of the lagging system and strengthen cross-sector cooperation in order to achieve the resource safety and continuous coordinated development of the WEF system.
