Study On Design Methods Of Multi-natural River

River is one of the important carriers of urban economic and social development.Design on the multi-natural river is the main approach to the ecological construction of urban rivers.In the basic research on the ecological management method of rivers at home and abroad,based on the current governance of the rivers in our country,especially on water quality deterioration,bulkhead serious artificialily and the degeneration of ecological system,studying on how to construct a multi-natural river with ecological characteristics is the demand of city waterfront development.The design theory of multi-natural river water coupled related important principle of conservancy science,ecology,landscape aesthetics.Meanwhile the design involved the landscape ecological planning principle,city waterfront space design theory,ecological restoration theory,eco hydraulic engineering principle,theory of sustainable development and other important theoretical results of multiple related fields.The study on multi-natural river started from the design concept,which devided into three levels: substance,life and consciousness,and transformed into the comprehensive design of ecological water conservancy,ecological restoration,ecological landscape,The corresponding design methods were aimed to restore the river morphology and improve water quality,recover the ecological system and protect habitats to build harmonious natural river landscape.Through linear design,embankment design and beach area design etc,the river ecological water conservancy design improve the the shape of river shoal area and surrounding environment,and realized the improvement of the stage on multi-river's material and shape.Ecological restoration design mainly includes physical repair design,bioremediation design,comprehensive repair of landscape ecological design.the repair engineering can be achieved in multi-natural river on life and biological level by using intercepting sewer,ecological floating island,wetland restoration and any other ecological restoration technology design methods and measure.The ecological landscape design feature the planning and design of waterfront space,cultural and natural landscape design and ecological landscape aesthetics design.It elaborates the multi-natural river landscape design theory from the overall layout,the natural and cultural landscape configuration design,multidimensional space ecological design and the ecological facilities and materials design,aimed at the sustainable development in the level of consciousness of the relationship between human and river.The design and construction of multi-natural river take the ecological water conservancy design as the core,the ecological restoration design as basis and the ecological landscape design as the focus.The three aspects complement each other and cross each other to aim to build mutual a healthy and dynamic river ecological landscape system.
