Planting And Design Of Plant Landscape In Liling Siqingdao Wetland Park Based On Low Maintenance

Urban wetland parks have irreplaceable ecological service functions in the urban green space system.The plant communities in the parks are involved in many special ecological functions,such as water conservation,water purification,microclimate regulation,flood control and drought resistance,and providing habitat for aquatic organisms.However,high-demand and high-quality plant landscapes require a lot of manpower,material and financial resources for later management and maintenance.Therefore,the study of low maintenance-oriented plant landscape is of great significance for building resource-saving urban gardens,reducing expensive labor costs and improving the ecological benefits of green space.This paper studies the plant landscape of low-maintenance urban wetland park and summarizes the technical means of low-maintenance plant landscape.Liling siqingdao wetland park site investigation,according to the current situation of the site,combined with low-maintenance plant landscape technical means to carry out plant landscape planning and design.The main achievements are as follows:(1)research is carried out by means of literature inquiry,data collation,field investigation and other research methods.Based on the relationship between the multi-disciplinary theories of arboriculture and phytocoenology and low-maintenance plant landscape design,this paper studies the plant landscape design of urban wetland park,and summarizes the technical means of low-maintenance plant landscape from three aspects:plant species selection,plant configuration and planting construction.(2)the plant landscape of 5 cases at home and abroad is selected for analysis,and the low-maintenance plant landscape construction measures that can be used for reference are summarized.(3)with Liling Siqingdao wetland park as the practical project,planning and design of the park's plant landscape through investigation and analysis.Different ideas of low-maintenance plant species selection were listed for aquatic plant community,water-resistant plant community and terrestrial plant community.The keynote tree species and landscape characteristic tree species are determined.The spatial types,colors and seasons of plants were planned.According to the different application forms of plant landscape in each area of the park,the overall maintenance difficulty classification area map is divided.Detailed plant landscape design is carried out for five important nodes.
