| The greenway is a kind of green open linear space which can connect various greenland in the city and ecological nodes or patches outside the city.It could not only optimize the ecological pattern of the city,but also enhance the city’s green network space system to improve the living environment.It’s an indispensable part of urban construction of ecological civilization and plays an important role in urban development.Inthe fact,many cities built the greenway with excessively pursuing short period and quick results,ignoring the long-term planning of the greenway and the systemic thinking of network construction.So that many greenway have been vacant in a long time.With a series of problems,some scholars and designers have payed attention to the master plan of the greenway.Green road network planning is one of the important means to realize ecological civilization city.Through the literature analysis,we have an objective understanding of the relevant theories of green road at home and abroad and the ideas and methods of green road network construction.Through the deep research on the green road network construction method,including the green road network construction goal,line selection scheme and so on.Secondly,through the analysis of the natural resources and environment conditions,regional development orientation,spatial pattern,road status and other factors in the study area,using the current river,road,resources and other factors integrated in the green road selection line,combined with the overall requirements of the green road upper planning in Chengdu,determine the green road selection standard,green road network spatial structure and system,that is,to reflect the "south city and north forest" of different towns and country ecological pattern characteristics as the goal,on this basis,the various elements of a systematic analysis and research,preliminary determination of the green road network construction layout structure,planning principles,strategies,laid the foundation for the construction of green road network.The research has researched the skeleton structure of the greenway in Wenjiang District,that is,the north-south direction greenways are longitudinally distributed along the water(Jiangan River Greenway,Jinma River Greenway,Yangliu River Greenway).And the east-west direction are in accordance with Chengdu greenway planning requirements and are ecological(second-round greenway and greenbelt around the city).Combined with the overall level division of Greenway in Chengdu,the Wenjiang Greenway not only was classified to city level,regional level and community level but also classified to urban type,country type and waterfront type.Through those greenways,the river channel,road and scenic spot resource nodes are effectively connected.Besides,Two networks,Four axes and Multiple nodes greenway system are formed in Wenjiang District. |
