Research on Resilience Enhancement and Sustainable Utilization of Water Networks in Plain Cities along Rivers and Seas

摘要:

以南通为研究对象，剖析其从单一水工程建设到全域水系统治理的演进路径。研究表明，面对平原河网水动力不足、水安全风险与高质量发展需求不匹配等问题，南通通过确立“系统化思维、片区化治理、精准化调度、长效化管护”的“四化”治水新理念，以构建现代水网为核心抓手，在保障水安全、改善水环境、优化水资源配置等方面取得了积极成效。然而，迈向新发展阶段，南通仍面临水安全韧性不足、水生态价值转化乏力、水文化引领作用未显等深层挑战。提出通过筑牢韧性防线、激活生态价值、塑造文化品牌、深化智慧赋能的发展思路，为沿海平原河网地区提供可资借鉴的治水兴水范式。

Abstract:

Taking the city of Nantong as the research object, its evolution path from single water project construction to the governance of the entire water system is analyzed. The research shows that facing weak hydrodynamics in plain river networks and a mismatch between water-security risks and high-quality development needs, the new water management concept of “systematic thinking, regionalized governance, precise dispatching and long-term management and maintenance” is established in Nantong. Taking the construction of a modern water network as the core approach, the positive achievements have been made in ensuring the water security, improving the water environment and optimizing the allocation of water resources. However, as Nantong enters a new stage of development, it still faces the deep-seated challenges such as insufficient resilience in water security, weak transformation of water ecological value, and the lack of prominent leading role of water culture. It is proposed to provide a model for water management and development that can be referred for coastal plain river network areas by strengthening resilient defense lines, activating ecological value, shaping cultural brands and deepening intelligent empowerment.
