The Design And Research Of Ecological Transformation Of Urban River

River has always played an important role in urban development. But with the changing needs of urban construction, the eighties of the last century, most of the rivers in the region have been built in the city of concrete drainage transformation-straightening, trapezoidal cross-section, concrete riverbed. However, after the transformation of the river, by the enormous destruction of ecosystems, urban river landscape is also stereotyped lost city diversity. Ecological transformation of urban river more and more attention, and as an important part of the urban landscape ecological construction. Is not a new topic about the river research work, but more than for the scope of the study, the entire river basin scales larger. Both the river and the city built in the region have different characteristics natural river, the river’s ecological transformation method is not suitable for many of the existing river city built in the region reality. In this paper, the status quo river city built in the region, features, combined with urban functions, river corridors, ecological restoration, flood control engineering safety, landscape design, summarizes a suitable method for the transformation of river ecology and technology city built in the region.The research results in general two aspects:one summarizes the relevant areas of ecological transformation of the city built in the area of research and practice both rivers results, analyze the theory and techniques; Second explored for urban built-up areas ecological river transformation method:From pre-planning analysis-channel morphology repair-riparian ecosystem restoration-riverside Landscape Design hydrophilic-water management technology methodology. When the river constitutes the ecological transformation of the transformation from the river, river bank protection, according to the spatial river riverside space. By planning ecological river Hainan Tunchang design, for example, improve the application of river ecological transformation methods and techniques, and achieved good ecological effects. Hopefully, this article studied the transformation of the way can inspire research and practical work on ecological transformation of the existing built-up areas of the city river.
