Research on the Path of Low-Carbon Sponge City Construction from the Perspective of Carbon-Water Coupling: Taking River Chief System as the Breakthrough Point

摘要

Taking the relations between urban water system and carbon system into consideration and making researches on the design link can dramatically cut the costs of urban duplication construction, improve efficiency on urban ecological civilization construction, enhance urban carbon and water environment and better people's living standards. In addition, it implements the five developing philosophies, Innovation, Coordination, Greenness, Opening, Sharing, and meets the requirements of constructing the "Wild China". Take the river chief system as the breakthrough point to explore the construction path of low-carbon sponge city. It is found that both the low-carbon sponge city or the river chief system, the ultimate goal is to maximize the concentration and use of limited water resources under the constraints of multiple factors, seek the best way to manage water resources, and further optimize the water ecological environment. The construction of the sponge town is guaranteed by the river chief system, while the low-carbon sponge city construction concept enriches the implementation content and objectives of the river system. Finally, it puts forward the specific path of building a low-carbon sponge city under the system of river length, such as improving the system construction, achieving the goal by layer by layer, narrowing the differences between urban and rural areas, and promoting the coupling of carbon and water.
