Description
Technical Field
The utility model relates to an environmental ecology field specifically says a sponge ecological parking area.
Background
The 'guidance suggestion about promoting sponge city construction' is clear, the influence of city development and construction on the ecological environment is reduced to the maximum extent through sponge city construction, and 70% of rainfall is absorbed and utilized on the spot. In 2020, more than 20% of the area of the urban built-up area meets the target requirement; by 2030, more than 80% of the area of the built-up area of the city meets the target requirement. From 2015, the construction requirements of sponge cities in new urban areas need to be fully met; the old urban area is to be combined with the transformation of shed house areas and urban and rural critical houses, the organic updating of old communities and the like so as to solve the problem of urban waterlogging, collect and utilize rainwater and treat black and odorous water as breakthrough, promote the overall treatment of the area, and gradually realize the relief of small rain, large rain, black and odorous water and heat islands.
The method has the advantages of popularizing the sponge type buildings and communities, the sponge type roads and squares, promoting the construction of urban drainage waterlogging prevention facilities and the transformation of waterlogging points, implementing rain and sewage diversion, building rainwater storage facilities in a scientific layout manner, and promoting the construction of park greenbelts and natural ecological restoration.
Under the promotion of related policies, the transformation of sponge honesty is continuously carried out. The parking lot occupies a large part of the area of the residential area, and has a very important position for sponge city reconstruction. However, the sponge in the parking lot is improved rarely, the grass planting bricks are paved mostly, the grass planting grids can play a part of landscape effects, and the sponge city can hardly be improved and constructed.
Therefore, in the sponge city transformation, the hardening pavement area of the parking lot is reduced, so that the comprehensive runoff coefficient is reduced, and the important point for solving the sponge transformation project is achieved.
Most ground parking area is the sclerosis area at present, and its application in the sponge city because under the order of relevant policy, the construction of sponge is indispensable, and because of the planning problem in many residential districts places, the space of sponge transformation is less again. Because the pressure intensity is considered, most of the current parking lots are grass planting grids and grass planting bricks. Most are combined with landscaping, but the sponge is not much modified.
