极端天气下特大型城市“水资源能源粮食”安全风险研究

Study on the security risk of“water-energy-food”in mega cities under extreme weather

以国内外特大型城市的极端天气事件和“水资源能源粮食”纽带关系的理论与实践为指导,分析极端天气下特大型城市外部水资源、能源、粮食压力突出问题,得出极端天气下特大型城市“水资源能源粮食”安全风险具有复杂性、安全系统具有脆弱性的特征;极端天气短期内激发了特大型城市资源需求,加剧了资源供应中断的风险,从而影响特大型城市资源安全。指出应通过“硬件”治理(韧性基础设施建设)和“软件”治理(“点线面”多主体协同治理)两个方面的安全风险韧性治理路径,应对当前极端天气下特大型城市“水资源能源粮食”安全风险治理的挑战。

Guided by the theory and practice of extreme weather events and the“water-energy-food”nexus in domestic and foreign mega cities,this paper analyzes the prominent problems of external water resources,energy and food pressure in mega cities under extreme weather,and concludes that the“water-energy-food”security risk of mega cities under extreme weather is complex and the security system is fragile,and extreme weather stimulates the resource demand of mega cities in a short time.It will aggravate the risk of resource supply interruption,thus affecting the resource security of mega cities.The security risk resilience governance path of“hardware”governance(resilient infrastructure construction)and“software”governance(point line surface multi-agent collaborative governance)is adopted to meet the challenge of“water-energy-food”security risk governance of mega cities under the current extreme weather.
