Example Embodiment

[0027] Example one

[0028] Such as figure 1 As shown, an embodiment of the sponge city unit system of the present invention.

[0029] The sponge city unit system of the first embodiment includes: urban arterial roads 1, circular walkways 2 and circular river channels 3 around. Among them, the main road 1 of the surrounding cities is enclosed into the planned area 10. The circular walkway 2 and the circular river channel 3 are located in the planned area 10, and the circular walkway 2 is located outside the circular river channel 3, that is, the circular walkway 2 is located in the surrounding cities. Between the main road 1 and the circular river channel 3. There is a building area 20 in the planning area 10. In the first embodiment, a building area 20 is formed between the circular walkway 2 and the surrounding city main road 1 so that the building area 20 is distributed along the surrounding city main road 1 On both sides. The annular river 3 is used to collect rainwater in ...

Example Embodiment

[0036] Example two

[0037] The second embodiment is an embodiment of applying the sponge city unit system of the present invention to the planning and design of urban functional service areas, taking Beijing as an example.

[0038] The Sixth Ring Road is the dividing line between Beijing’s urban and suburban areas. It extends five kilometers inside and outside along the Sixth Ring Road to form a 10-kilometer-wide ring zone with an area of ​​approximately 1,200 square kilometers. An urban functional service area is established in this area. The urban functional service area is planned and designed according to the sponge city unit system mode of the present invention. Each sponge city unit system is a minimum of two kilometers by two kilometers of land, of which the urban agricultural park area occupies about one square kilometers, so that a quarter of the urban land is used for the urban agricultural park area. Establish three railway passenger stations of the same scale in the s...

Abstract

The invention relates to the technical field of urban planning design and urban water conservancy facilities, in particular to a sponge urban unit system.The system comprises a surrounding urban main road and an annular watercourse, wherein a planning region is defined by the surrounding urban main road, and a building region is arranged in the planning region; the annular watercourse is located in the planning region to be used for collecting rainwater in the planning region; an urban agricultural garden region is defined by the annular watercourse, an urban waste disposal region is arranged in the urban agricultural garden region, and sewage pipelines used for guiding sewage in the building region to the urban waste disposal region are laid in the planning region.In this way, urban rainwater is kept in cities, disposed locally and recycled, urban sewage and organic waste are digested and absorbed, urban afforestation and beautification can be achieved through the urban agricultural garden region, the agricultural product requirement of cities can be provided partially, ecological cities are realized, and environment pollution, water resource shortage, urban inland inundation, urban heat island effect and other city problems are solved.

Description

technical field [0001] The invention relates to the technical field of urban planning and design and urban water conservancy facilities, in particular to a sponge city unit system. Background technique [0002] With the continuous development of cities, many "over-urbanization" phenomena have emerged, resulting in a series of contradictions and problems called "urban diseases": traffic congestion, environmental pollution, water shortage, urban waterlogging, urban heat island effect, etc. Wait. [0003] Every detail of urban planning and construction must consider the impact on nature, let alone break the natural system. Why are so many cities short of water? An important reason is that there are too many concrete floors, which occupy forest land, grassland, lakes, and wetlands that can conserve water sources, cutting off the natural water cycle. When rainwater comes, it can only be drained away as sewage, and the groundwater is getting less and less. To solve the problem ...
