Voice of Yibo | Zhang Linwei: The concept of sponge city must be "standard" in urban construction

Zhang Linwei, President of the Chinese Town Water Supply and Dentaner Association:

The concept of sponge city must be "standard" in urban construction

Under the influence of the concept of traditional urban construction, excessive hardening under the cities brought about by urban development and construction affects the natural cycle of water. A large amount of rainfall forms a fast runoff on the surface. Only a small number of rainwater can enter the underground, showing a hydrological phenomenon opposite to nature, destroying the natural ecological bottom, and the so -called "rainwater and drought after the rain." The construction of sponge cities is a modern urban development concept. By strengthening the management of urban planning and construction, fully give full play to the effects of absorbing, exudating, and slow release of ecosystems such as construction, roads and green spaces, and water systems to effectively control rainwater runoff and achieve natural accumulation of natural accumulation , Natural penetration, natural purification.

For the construction of the new city, the concept of sponge city construction is the goal. my country has previously proposed "sponge+", and now it is proposed "+sponge", because in the pilot process, it has accumulated good experience in the construction of the sponge city, so now it is updated in urban renewal, drainage and waterlogging, and black odor water governance treatment. , Diversion of rain and diversion, smart water, emerging industries, etc., you can see the practice and methods of the construction of sponge cities. From pilot to comprehensive promotion, the concept and method of sponge cities, as standard in urban construction, must be done like a pipeline.
