Urban Flood Disaster Control Based on Green-gray-blue Infrastructure Integration
摘要
With the increasingly severe urban waterlogging situation, It was difficult for rainwater management with rainwater pipe network and other grey infrastructures for terminal rapid drainage to solve the problem of urban waterlogging fundamentally. And combining the green, grey and blue infrastructure organically could besides on ensuring that urban floods were effectively solved, systematically solve multi-scale problems such as water pollution and water shortage. Based on the concept of green-grey-blue infrastructure integration, this study reviewed the comprehensive evaluation of urban stormwater system status, the optimization of urban stormwater system, and urban flood control and drainage scheduling. In terms of urban stormwater system assessment, the performance assessment of low impact development system with green infrastructure as the main body and the performance assessment of urban stormwater pipe network system with gray infrastructure as the main body were reviewed. In terms of urban stormwater system optimization, the optimization of design parameters and layout of green infrastructure and the optimization of plan layout and pipe diameter depth of gray infrastructure such as pipe network was reviewed; in terms of urban flood prevention and drainage scheduling, the study of urban flood prevention and drainage was reviewed. In urban flood control and drainage scheduling, the research on urban flood control and drainage scheduling methods and urban flood control and drainage scheduling systems were also reviewed.
