The Study Of Ecological Restoration And Landscape Optimization Of Northern Riverside And Lakeside Water Front

Together with the deterioration of riverside and lakeside water front ecological environment and the elevation of urbanization level,riverside and lakeside water front occur severe ecological problems which devastate the unique waterside landscape of rivers and lakes and pollute the water quality to some extent.As a result,in order to assure the stability of water front ecological system and the diversity of waterside landscape,it is necessary to explore the riverside and lakeside water front construction and landscape design strategies and methods suitable for northern regions.Taking ecological restoration as the benchmark,this thesis specifically analyzes the ecological patch problems based on the analysis and summary of domestic and overseas restoration cases and raises some solutions for water front ecological restoration and landscape reconstruction in northern cities.Firstly,the framework of northern riverside and lakeside water front landscape restoration under the theories of landscape ecology,restoration ecology Later on,the problems of northern small and medium riverside and lakeside water front are figured out through the investigation.Accordingly,the ecological problems in Wei River basin and the necessity of landscape restoration turn increasingly essential.Next,this thesis describes the landscape construction design methods under northern river and lake ecological restoration system.In other words,it starts from the comprehensive functions of water front to protect the micro-landscape of water front,restore the physiological base of water font,break original hard riparian,build artificial wetland,establish and improve botany-oriented biodiversity water-land ecotone phytocoenosium in water front landscape planning.Above-mentioned strategies are applied in landscape planning and water front ecological system restoration.Pursuant to the exclusive longitudinal division of water front,it is also feasible to use hierarchical division design ideas.Different riverside and lakeside water fronts are applicable for different ecological countermeasures and solutions.Briefly speaking,this thesis adopts longitudinal division concept to discuss about the practice in northern regions.In the end,this thesis takes Wei River landscape comprehensive governance planning design plan in Weinan city as the example and combines previous theories to build and improve water front green gallery through intensifying landscape matching and combining agricultural botany landscape,lotus pond botany landscape,wetland and embankment botany landscape,and ecological riparian.The presentation of divisional key design supports the argument of this thesis.
