Abstract
The total area of waterlogged regions nationwide is approximately 894 million mu.By the end of the 14th Five-Year Plan(2021-2025)period,the cumulative area that has been drained and improved exceeds 380 million mu,accounting for about 43％of the nation's total waterlogging-prone area.As for the untreated areas,prominent challenges remain,including inadequate drainage engineering systems,insufficient capacity alignment,imperfect operation and maintenance mechanisms,and the need for enhanced coordination between regional drainage and basin-scale flood control.During the 15th Five-Year Plan(2026-2030)period,extreme weather events,high-quality economic and social development,the national food security strategy,comprehensive rural revitalization,and high-quality water conservancy development have all created urgent demands for waterlogging control.Emerging technologies such as digital twins provide important support for enhancing waterlogging management capabilities.Given the new situation and new requirements,it is recommended that key projects be taken as the starting point,and efforts be promoted in a coordinated manner across four dimensions:clarifying the current status,project layout,measure selection,and management/maintenance scheduling.Systematic investigations and assessments of waterlogged areas should be carried out,the scope of management and waterlogging control standards should be scientifically defined,project layouts and control measures should be optimized according to local conditions,and the construction of backbone projects,field works,and digital/intelligent infrastructure should be advanced simultaneously.Furthermore,a long-term operation and maintenance mechanism should be improved,so as to comprehensively enhance the overall capacity for agricultural disaster prevention and mitigation,thereby providing solid water conservancy support for safeguarding national food security and promoting high-quality regional development.关键词
