Explore The Green Space Network Planning Methods Of Nanyang City Which Rivers And Green Space Are Coupled

Green space ecological network is the inevitable trend of urban greensystem planning, in order to promote Nanyang city develop sustainably, and improvethe ecological environment quality and the living environment, this paper selectNanyang City rivers and green space as the research object to explore method ofgreen space network planning of Nanyang city through the coupling between the two.Nanyang is one of the areas which river network is relatively dense in Henanprovince, abundant rainfall, rivers and water resources is extremely rich, the riverplays an important role in the Nanyang urban green space system layout, many greenspace focuses on both side of White River, and the others also process "branches"type layout along the river. Therefore, put forward based on the river network, usingthe coupling relationship between the rivers and green space to construct the urbangreen space ecological network of Nanyang city. Select this planning method for threereasons:①The efficacy of green space ecological network depends on the structuralof the network, urban river network structure is complex and stability.②River is alinear continuum and can be the guidance of the urban green space layout.③Riversled the formation of urban green space, and are coupled with green space on thespace.Coupled with the Green River in Nanyang city were from three aspects ofmacro scale, meso scale, micro scale: the macro scale, first improve the continuity andintegrity of the Nanyang River, and then along the layout protection green land andriverside green space, to enhance the function of recreation, ecology River perfectecological system of urban green space in Nanyang city; the meso scale, to river andsurrounding green space as an example, the connecting role of Baihe, by extension,connection, development, recognition and promotion, increase the space interfacewith surrounding green space and other linear corridor, the formation of landscapepattern of green space network. The micro scale, to the people’s Park and adjacent to the river as an example, through the coupling of visual, geometric and functional,ensure the outdoor space coherence, increasing landscape recreational green spacenetwork.Finally, use the Network structure analysis to analysis the Nanyang city greenspace network based on the current situation and the planning graph of Nanyang citygreen space systeme. Analysis, Nanyang city green space network connection degreereached0.35, line rate reached1.28, the closed degree reached0.16, the networkbegan to form, the connection degree has more than doubled, especially the line rate isgreatly improved, this proof strategy construction of green ecological network relyingon rivers and green space coupling the obvious. But the line rate index1.28justgreater than1, the average per node is only a connecting corridor, this is far fromenough to build a green ecological network. Connectivity index0.35, not more thanhalf, that node for establishing a connection between the possibility is still very great,still need to continue to strengthen the corridor construction. Closing index0.16, theclosing degree of the network is still relatively low, the main reason is the basis ofgreen construction in Nanyang City, still need to strengthen the green spaceconstruction and river protection, increase the green area and quantity, at the sametime pay attention to corridor construction, establish more scientific and efficientgreen ecological network.
