Abstract：The construction of the national water network and the safeguarding of water ecological security are core tasks for the water sector now and in the future.Accurately understanding the dialectical relationship between the two is crucial for promoting high-quality development and providing high-level water security for Chinese path to modernization.This paper elaborates on the importance of the national water network in ensuring ecological security from the relationship between the construction of the national water network and six aspects:the overall framework of China's ecological security,the protection and restoration of the northern ecological barrier areas,the ecological restoration of rivers and lakes in water-scarce regions,the recovery of groundwater in over-exploited areas,the improvement of river and lake water quality,and the protection of important wetlands and biodiversity.A scientific analysis is provided on the potential impact of the planning,construction,and operation of the national water network on ecological security.Several measures are proposed to promote the coordinated advancement of the national water network construction and ecological security safeguarding:optimizing the overall layout of ecological security and clarifying the water resource demands for ecological security in key regions;planning and constructing a national water ecological network within the framework of the national water network;maintaining and enhancing the function of groundwater as an emergency water source to build a three-dimensional national water network;reducing pollution at the source and strengthening local governance to build a clean water network;leveraging the role of strategic water source reserves to mitigate the impact of large-scale water diversion on the Yangtze River basin;and enhancing the research and application of green technologies throughout the life cycle of water projects.
