摘要
以安徽省为研究对象,建立水-能源-粮食(W-E-F)耦合协调模型,测算出其2006—2018年的W-E-F系统发展水平和耦合协调度,并分析其时空变化特征。结果表明,2006—2018年安徽省W-E-F系统的综合评价指数整体呈上升趋势,耦合协调度从0.4909上升到0.8702,总体达到良好协调水平;但是各子系统的发展特征不同,水资源子系统变化波动比较大,能源子系统发展相对来说比较缓慢,粮食子系统发展较快,开发利用水平整体上高于水资源和能源;W-E-F系统协调水平也存在显著的空间差异;合肥、淮南和宣城三市的协调水平较高,各子系统的短板区域主要位于六安、马鞍山、淮北等地。大多数地区面临W-E-F内部发展日益失衡问题,其中粮食和水资源之间的矛盾最为突出,故需要颁布节水政策、提高节水灌溉效率,减轻粮食生产对水资源造成的影响。
Taking Anhui province as the research object,the coupling coordination model was constructed to measure the development level and coupling coordination degree of water-energy-food(W-E-F)nexus from 2006 to 2018.In the meantime the spatial and temporal characteristics of the nexus was analyzed.The results show that from 2006 to 2018,the comprehensive evaluation index of the W-E-F system in Anhui province has presented an overall upward trend,and the coupling coordination degree has risen from 0.4909 to 0.8702,reaching a good coordination level as a whole.However,the development characteristics of the various subsystems are different.Water resources subsystem has large fluctuations,energy subsystem develops relatively slowly,and food subsystem develops rapidly,and the overall development and utilization level is higher than that of water resources and energy.There are also significant spatial variation in the coordination level of the W-E-F system.Hefei,Huainan and Xuancheng have a relatively high level of coordination,and the weak areas of each subsystem are mainly located in Lu’an,Ma’anshan,Huaibei and other places.Most regions are facing the problem of increasing imbalance in the internal development of W-E-F system.Among them,the contradiction between food and water resources is the most prominent.It is necessary to promulgate water-saving policies,improve water-saving irrigation efficiency,and reduce the impact on water resources caused by food production.
