Sponge city system and construction method thereof

Abstract

The invention provides a sponge city system and a construction method thereof. The system comprises an ecological barrier area arranged close to a river, a leisure industry area arranged close to theecological barrier area and an urban living area arranged close to the leisure industry area. A first ecological footpath is arranged on a river levee of the river, and the ecological barrier area isarranged on the outer side of the first ecological footpath. A footpath is arranged in the ecological barrier area for people to walk through, and an ecological three-dimensional sewage interception system and an intelligent service station are arranged in the ecological barrier area. A second ecological footpath is arranged on the outer side of the ecological barrier area, the leisure industry area is arranged on the outer side of the second ecological footpath, and a tourism service module, an urban agriculture module, a rural living module and a sewage treatment plant are arranged in the leisure industry area. A regional road is planned on the outer side of the leisure industry area, the urban living area is planned on the outer side of the regional road, and an ecological corridor communicating with a sewage treatment plant is arranged in the urban living area. The system can fundamentally solve the problems of water environment, urban inland inundation and unreasonable urban functions.

Description

technical field [0001] The invention relates to the field of urban planning and water environment management, in particular to a sponge city system and a construction method thereof. Background technique [0002] Rivers are an important factor in the formation and development of cities. With the advancement of urbanization, various water environment problems have appeared in rivers around many cities. A large number of urban constructions have changed the original relationship between nature and man-made. Concrete pavement blocks rainwater runoff into nature. Rivers lose their ability to absorb, purify, and discharge due to urban pollution and floods. Cities are flooded due to drainage problems. As resources and elements continue to gather in cities, the process of urbanization has made the functions of cities more complex, the needs of residents more diverse, and the isolation between cities and villages has become more serious. In order to solve the increasingly serious p...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing sponge city systems focus on taking engineering measures to disperse the construction of pipeline networks, without considering the urban and rural areas as a whole, and without considering the solution to water environmental pollution and urban waterlogging from the perspective of the rationality of the internal functional composition of the city. Carry out systematic planning and solve problems starting from the compositional relationship of cities, villages, rivers and various functions of cities
