Research On Landscape Design Of Mountain Green Campus Under The Concept Of Low Impact Development

On the one hand,the construction of sponge city in China inherited the wisdom of ancient sages,on the other hand,it referred to a lot of foreign experiences,which includes low impact development,and low impact development is also one of the important guiding ideology and core technology of sponge city.Under the background of the promotion of low impact development mode in China,the construction of mountain campus needs to keep pace with the times.The problems accumulated in the visual image,function and runoff control of campus landscape space need to be solved.Compared with flat campus,the landscape planning and design of green campus in mountainous areas is facing challenges due to its regionalization characteristics,but it also provides a good opportunity for the study of landscape specific design strategies of mountain green campus.In the development of low impact development theory,foreign research has been inspired from agricultural production,and began to try to use landscape facilities to treat rainwater.The related research is developed gradually,which extends the low impact development technology from agriculture to city,and then integrates it into campus construction,and emphasizes that rainwater facilities should have both function and landscape.Domestic research reflects on the process of sponge city construction,discusses the localization understanding of low impact development,and emphasizes the visibility,participation and teaching significance of green campus landscape design.Because of the difference between layout and volume,landscape planning in different education levels is different.According to the different education levels,plane layout and vertical space,the mountain campus is classified.Each type selects Chongqing sample campus,and takes the low impact development as the guiding ideology,analyzes and summarizes the common problems existing in traditional mountain campus,including "slow flow low efficiency and poor image" : large hard area around the building and lack of green rainwater facilities,The aesthetic value of landscape space is not enough“ Poor integrity and partial fault: the lids from top to bottom have not been rainwater management system,and the special boundary space of mountain campus is seriously waterlogged and the visual image is poor“ The soft and hard landscape is not related to the hard landscape,the campus green space is bare,the utilization rate is low and the maintenance is difficult“ The pursuit of form and lack of characteristics: campus landscape design is in conflict with the main use function of landscape space,and the runoff control effect is in conflict with the main use function of landscape space.The analysis and summary of the research provide a reference for the next step of research and design strategy.Based on the summary of theoretical research and research,the thesis proposes the strategies of low impact development combined with landscape design of mountain green campus according to the specific space of mountain campusFirst,Buffer progressive-efficient slow flow,technology integration: green facilities replace gray facilities,soft landscape buffer hard landscape,pay attention to the integration of lid landscape technology and art;Second,Level by step-layer by layer regulation,up and down linkage: platform and retaining wall,steps and flat,slope and flat space,and other spaces,from top to bottom,integrated lid landscape design is carried out to highlight the mountain characteristic landscape;Third,Local concentration-combination of soft and hard,and various functions: in the large-scale and deep landscape space,multiple lid landscape facilities are designed in linkage,while in small-scale space,a variety of lid facilities cooperate with each other to create a distinctive campus landscape;Fourth,Multi compound-according to local conditions,the characteristics are remarkable: according to the actual conditions of the site,the design strategies of "buffer progressive","hierarchical layer by level" and "local concentration" are adopted comprehensively for the mountainous campus with complex architectural layout.From three different education levels of mountain campus,a typical case is selected to analyze the factors influencing the site environment,topography,low impact development and design and the demand of users.Then,the thesis uses lid scale calculation as the design support,and combines the landscape design strategies summarized in Chapter 4 to verify the feasibility and implementation of the thesis view,It provides reference for landscape design of new mountain green campus.
