Soil and water salinity regulation system and regulation method for sponge city green infrastructure

Abstract

A sponge city green infrastructure soil and water salinity control system, including a roof runoff control system, a municipal road surface runoff control system and a green space runoff control system; the roof runoff control system includes pebble channels, biological retention facilities, rainwater storage tanks, roof Rainwater collection pipe network, low-salinity body and green drip irrigation system; the municipal pavement runoff control system includes initial abandoned flow rainwater wells, pebble canals, belt-shaped low-potential green spaces, biological retention facilities, rainwater storage tanks, and municipal pavement rainwater collection pipe network , medium saline water body and green drip irrigation system, bioretention facilities are arranged at intervals in the strip-shaped low-potential green space, and collect the road surface runoff pretreated by the strip-shaped low-potential green space; the green space runoff control system includes low-potential green space, rainwater storage tank, Green land rainwater collection pipe network and high salinity water body. The invention can effectively recycle and utilize unconventional water resources, regulate the salinity of soil and water bodies, ensure water safety, and shape water landscapes.

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...
