A Study On Landscape Building Of Constructed Wetland In Guanzhong Area

Nowadays, constructed wetland has become a new carrier of constructing thegreen landscape of cities under the upsurge of focusing on ecological benefits fordecades. It has very important social value in improving urban space environment. Theconstructed wetland landscape in garden landscape has become an organic part, andformed the unique ecological landscape, because more and more attention has been paidto it, in-depth research on the green scientific and technological environment has beencarried out, and the desire to returning to natural ecological environment has been great.However, for Guanzhong area which has a low environment quality, the currenturban landscape should be designed to have external beauty, and also the influence oncity space produced by its cyclic development in the long run should be taken intoconsideration. Building urban landscape combined with constructed wetland canbeautify city image, improve the citizens’ well-being, and can play a very important rolein part sewage purification which can facilitate secondary utilization and save waterresource. It can not only provide functional requirements for urban construction inGuanzhong area, but also supplement the local ecological benefit and humanisticculture which stress its social values. Therefore, how to construct the urban landscape toimprove ecological environment in public urban space and make use of naturalresources sufficiently and reasonably is a very important problem to be solved.Based on Guanzhong area, the paper has constructed wetland landscape as itssubject, and will have a systematic understanding on the functions and features of itselements and their relationship according to the relevant materials such as naturalclimate, geology and geomorphology, hydrological conditions, urban landscape in thearea to analyze the possibility and conditions to build constructed wetland landscape inthe area. Based on this, the paper will have a comprehensive analysis from several aspects of establishment condition, construction principles, plant selection, waterstreatment and other landscape elements of constructed wetland. And then it will explorethe relevant principles of building constructed wetland landscape in the area. At last, itwill put forward the related theory of building urban wetland landscape. It will analyzethe assignment problem of aquatic plants and the plant selection of the constructionsystematically. Meanwhile, its later maintenance will realize its sustainable and cyclicdevelopment. This is not only to optimize the mode of natural ecological environmentof the area and to provide important theories of landscape building for the local publicspace, but also it can improve the spatial ecological environment, beatify city image ofthe area and maximize the function of urban garden landscape. So this study canprovide reference value to local urban garden construction and also has important socialsignificance to the construction of urban green garden in Guanzhong area.
