| 【目的】为全面把握河南省水-能源-粮食纽带关系、科学评估水-能源-粮食协同安全水平。【方法】本文首先对水-能源-粮食纽带关系进行解析；在此基础上，阐述水-能源-粮食协同安全的概念、内涵及判断准则，构建评价指标体系；采用“单指标量化-多指标综合-多准则集成”方法，对河南省水-能源-粮食协同安全水平进行评估。【结果】研究表明：2001~2019年间，①河南省水生产与供应业的能源利用效率及能源生产过程的水资源利用效率不容乐观，亟需提升工艺技术，逐步实现节水节能的双赢目标；②粮食灌溉的用水效率有所提升，农业节水取得一定成效；粮食生产的能耗结构趋于合理，其中电力消耗占比增加19.74%，柴油、化肥和农药消耗的占比分别降低10.34%、5.98%、3.42%，逐渐向清洁及环境友好方向转变；③水-能源-粮食协同安全从0.46的基本安全水平过渡到0.6的较安全水平；前期与能源安全水平、经济社会发展水平关系密切，后期逐渐受到水资源、粮食等基础性资源的制约；④各准则层中，水资源安全水平较低，长期处于[0.2，0.4)的较不安全水平，且年际波动较大；粮食安全水平较高，长时间保持较安全或安全的状态。【结论】河南省水-能源-粮食协同安全水平有待进一步提高。 |

| Abstract: |
| 【Objective】To fully grasp the water-energy-food nexus and scientifically evaluate its synergy security in Henan Province, 【Method】this research firstly analyzed the water-energy-food nexus. On this basis, the concept, connotation and evaluation criteria of water-energy-food synergy security were introduced, and then established an evaluation index system, the water-energy-food synergy security in Henan Province was evaluated by adopting the evaluation method of single index quantification and multiple index synthesis and policy-criteria integration (SMI-P). Concretely, the first step of the method is single index quantification, the fuzzy membership function is used to map each index to [0,1] by assuming that there are multiple node values of each index. Secondly, the index of each criterion layer is calculated by summing the membership degree of each index weighted. Thirdly, the index of the target criterion layer is calculated by summing each criterion layer weighted.【Result】Results showed that during 2001-2019, ①the energy utilization efficiency in water production and supply and the water resources utilization efficiency in energy production were not optimistic, it would be urgent to improve technology, therefore the win-win goal for water and energy saving would be gradually achieved; ②water utilization efficiency in grain irrigation was improved, and agricultural water saving achieved certain results; the energy consumption structure in food production became more reasonable, and changed towards a clean and environmentally friendly direction; among them, the proportion of electricity consumption increased by 19.74%, and the proportion of diesel, fertilizer and pesticide consumption decreased by 10.34%, 5.98%, and 3.42%, respectively; ③water-energy-food synergy security changed from basic security level (0.46) to the relatively safe level (0.6); during the early stage, it was closely related to the energy security and the economic and social development, and in the later stage, it was gradually restricted by basic resources such as water resources and food; ④the level of water resources security was low, with large inter-annual fluctuations, remaining at a relatively unsafe level of [0.2, 0.4) for a long-term; while the level of food security was high and always maintained a relatively safe or secure state. 【Conclusion】The level of water-energy-food synergy security in Henan Province needs to be improved. |
