Soil and water salinity regulation and control system for green infrastructures of sponge city and regulation and control method

Abstract

The invention discloses a soil and water salinity regulation and control system for green infrastructures of a sponge city. The system comprises a roof runoff regulation and control system, a municipal road runoff regulation and control system and a greenbelt runoff regulation and control system, wherein the roof runoff regulation and control system comprises a pebble canal, bioretention facilities, a rainwater storage pool, a roof rainwater collection pipe network, a low-salt water body and a greening drip irrigation system; the municipal road runoff regulation and control system comprises aninitial discarding rainwater well, a pebble canal, a strip-shaped low-terrain greenbelt, bioretention facilities, a rainwater storage pool, a municipal road rainwater collection pipe network, a medium-salinity water body and a greening drip irrigation system, and the bioretention facilities are arranged in the strip-shaped low-terrain greenbelt at intervals and used for collecting road runoff pretreated by the strip-shaped low-terrain greenbelt; and the greenbelt runoff regulation and control system comprises a low-terrain greenbelt, a rainwater storage pool, a greenbelt rainwater collectionpipe network and a high-salinity water body. Unconventional water resources can be effectively recycled, soil and water salinity is regulated and controlled, water safety is guaranteed, and a water landscape is built.

Description

technical field [0001] The invention relates to the field of sponge city construction, in particular to a soil and water body salinity control system and control method for green infrastructure of the sponge city. Background technique [0002] Sponge city construction is the transformation of urban development concepts and construction methods, and is an important concept and measure to promote green and sustainable urban development. Through the construction of green infrastructure such as permeable pavement, green roof, sunken green space, rain garden, wetland or wet pond with the functions of "seepage, stagnation, storage and purification", combined with the comprehensive storage and drainage functions of the urban water system, While reducing rainwater runoff, purify, infiltrate and store rainwater, conserve groundwater or use it for municipal irrigation and ecological water replenishment, so that rainwater resources can be effectively controlled and utilized, and "light...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a sponge city green infrastructure soil and water salinity control system, to solve the problem of high groundwater level and high salinity in the northern coastal saline-alkali areas, which lead to the sponge city green infrastructure plant landscape A series of problems such as difficult construction, low operating efficiency of facilities, limited use of rainwater with high salinity, and difficulty in ecological restoration of high-salinity bodies and improvement of water environment
