沿海城市人工湖的智慧化韧性管控——福州市晋安湖案例OA

[Objective]This paper addresses the multiple challenges faced by urban artificial lakes in southeastern coastal cities,including high waterlogging risks,significant water quality fluctuations,and weakened ecological functions against the backdrop of global climate change and frequent extreme weather events.It proposes and implements a comprehensive smart management and control framework for urban artificial lakes,aiming to enhance the safety resilience and ecological service functions of the lake water system.[Methods]This paper proposed an integrated smart management and control framework for urban artificial lakes in southeastern coastal cities,based on recent advances and practical achievements in smart lake management technologies.The framework encompassed a comprehensive chain of solutions,including a"sky-air-ground"integrated monitoring network,a multi-model coupled early warning system,and a dynamically optimized scheduling mechanism.[Results]In the case study of Jin'an Lake,Fuzhou City,Fujian Province,the smart management and control system enabled the lake area to withstand over 10 typhoons and 100 short-duration heavy rainfall events.Furthermore,key water quality indices showed significant improvement:average concentrations of ammonia nitrogen and total phosphorus decreased by approximately 30％and 25％,respectively,compared to pre-implementation levels.Other critical parameters had remained stably within Class Ⅲ or higher of the national surface water quality standards.The system had effectively enhanced the resilience of the urban artificial lake system in this southeastern coastal city,providing practical evidence and valuable insights for the smart management of similar artificial lake areas.[Conclusion]In future,smart management of artificial lakes requires strengthened integration of digital technologies and coordinated regional water systems to transition from traditional hydraulic facilities to smart ecological infrastructure.A joint regulation platform for river-lake systems based on watershed boundaries should be established,providing technical support for water security and sustainable development in southeastern coastal cities,while offering scalable paradigms for resilient and smart urban water system governance.
