- Abstract:
- In the process of promoting the construction of sponge city, addressing the strategic challenge of how to scientifically create a sponge city engineering system that integrates blue, green, and gray facilities tailored to local conditions, to enhance the systematic, scientific, and construction efficiency of sponge city initiatives, has emerged as a significant issue for many cities in China. Using the construction planning of Yushu City’s sponge city as a case study, this paper presents the technology, methods and implementation strategies for integrating blue, green and gray facilities. These methods include enhancing the function of the large sponge system in the basin to store and purification through measures such as “strategic planning, increased irrigation, and slope protection”, improving the mountain torrent control system with “upstream regulation and downstream discharge, blue-green integration”, “optimizing vertical drainage system and combining storage and discharge” to prevent waterlogging, constructing source land sponge facilities with “natural organization and distinct attributes”, and concluding with comprehensive project planning through “comparing multiple schemes and model simulation evaluation”. The ultimate goals of sponge city construction, including enhancing river basin water conservation capacity, mitigating urban flash floods and waterlogging risks, improving urban living environments, showcasing national characteristics, are achieved through this approach.
