Research On The Landscape Design Of Sponge Facilities In Innovation Port Middle School Of Fengxi New City

Fengxi New Town is the first batch of Sponge city construction pilot area in China.The middle school campus has a compact spatial layout,limited green space area and is characterized by decentralization and fragmentation.This article takes Fengxi New City Innovation Port Middle School as the research object,exploring how to achieve the landscape design of sponge facilities on high school campuses without affecting the outdoor activity space needs of middle school students.It not only meets the requirements of regulation goals,but also has certain landscape effects,and can also be used for ecological environment education,which has practical promotion value.In response to the above issues,this study proposes a landscape design method for sponge facilities in Innovation Harbor High School through habitat creation,landscape element analysis,and coupling analysis.It is mainly carried out from the following three aspects:First,this paper summarizes the relevant theories and methods of the sponge facility landscape design of the middle school campus,and conducts a detailed investigation on the Fengxi New Town buildings and residential areas,and combs the characteristics of the space layout of the middle school campus buildings,the types of underlying surfaces and other factors affecting the production and concentration of the site,coupling to propose the Partition type types of the middle school campus catchment.Secondly,summarize and screen the types of sponge facilities suitable for the physical and mental characteristics of middle school students,and classify and organize them;Based on the characteristics of catchment area and campus green space layout,sponge facilities are combined with landscape functional space,and sponge facilities combination,layout and form design are carried out for different landscape space units.Project practice research is carried out in combination with Innovation Port Middle School,and the overall layout of sponge facilities green space is verified to be scientific and accurate through SWMM platform Analog verification.Finally,based on the dominant function of the campus landscape space unit and the spatial distribution form and habitat conditions of sponge facilities,the plant planting design model of Rain garden,sunken green space,grass planting ditches and high-level flower beds in the site was studied.Based on the current characteristics of the compact spatial layout and fragmented green space of Innovation Port Middle School,the main research conclusions of this paper are as follows:(1)Middle school campus can be divided into six types of landscape space units:square display type,courtyard activity type,playground sports type,road access type,green space Ecotype type and roof science and education type,of which the proportion of facility green space in the landscape space units dominated by activity function can be controlled at about 10%.(2)Combined with the Functional requirement of middle schools and the distribution characteristics of green space,three types of spatial layout of sponge facilities are summarized,namely,point scattered,linear arranged,and area centralized,and the combination and layout forms of sponge facilities in different landscape space units are proposed.(3)Based on the spatial layout form,habitat conditions and landscape Functional requirement of sponge facilities,three plant planting modes of Rain garden dominated by landscape and ecological functions,two plant planting modes of sunken green space adjacent to the vehicle or pedestrian passageway,two plant planting modes of transmission type and detention type grass planting ditches,and two plant planting modes of elevated flower beds connected with roof downpipes and drainage pipes in buildings.
