| The city rapid develops so that the issues of the spread of urban space,urban population growth,increased traffic congestion,environmental degradation,and human settlements stand out more and more.Greenways as green infrastructure with multiple functions,plays an important role in solving urban problems.Zhengzhou is the core city of central Henan urban agglomeration,so how to deal with the ecological and energy crisis in the urbanization process of rapid development,realize the urban living environment of harmonious and sustainable urban planning and construction that is important and difficult.Taking build ecological and suitable city as the guiding,the paper,from a multidisciplinary coherence perspective,has made the Zhengzhou city territory and the Zhengzhou metropolis core area as the study scope,and used remote sensing technology and landscape analysis,combined with the practice of research,data from physical space Comparative analysis,identified the current Zhengzhou greenway space problems as a guide to build a network of greenway space,from space,planning,ecological three aspects proposed scientific reference for Zhengzhou greenway construction.The main contents and conclusions are as follows:Firstly,the paper has sorted the theory,research development and of construction case about the greenway.Secondly,the paper has made the Zhengzhou metropolis core area as research object,surveyed the status of some sections and made POE analysis,analyzed space and landscape ecological effects of typical sections,summarized in Zhengzhou City greenway space problems.The paper has the conclusion is that the currently Zhengzhou greenway was lowly used,ecological network has not been established,and public transit links been inadequate,the effective management mechanism been lack,the legal status of greenway planning also not been identify.Specific ways to enhance that it improves the aesthetic connotation accessibility and space to increase the space vitality greenways,and carries greenway space construction from local conditions sub-standard,promotes the depth greenway ecological network,and also it should improve greenways control measures,achieves vertical hierarchy through construction,lateral strengthening regional co-management network.Thesis on urban planning and construction of green channel space is studied and concluded:(1)Urban greenway space should couple with urban space from city landscape pattern,urban open space,transportation main skeleton,high-density plots,historical and cultural resources,urban context style six aspects.(2)Basic unit(“green belt + green corridor + green wedge + green core ”)concept was proposed for greenway space,and noted that the trend towards ecological greenway network development.The paper has analyzed the spatial unit pattern from the city territory,the core city,community three levels,combed the different levels of greenway space elements,morphological features,and the greenway space combination mode.Thesis focuses on the Zhengzhou ecological networks greenway space Construction research.The basis for a lot of basic data collection,interpretation and analysis in the use of remote sensing technology,the paper has combined with the relevant statistical data of the Zhengzhou City,through situation analysis identifying potential structural Zhengzhou ecological greenways network space that it can be build,build the city territory and the core city green spatial pattern,and has comparative analysis the core city of Zhengzhou mainly ecological network node ecology,ecological corridor,network models.The paper has used GIS,FRAGSTATS to technically analyze the scientific core city greenway space ecological networks.The data analysis showed that the greenway space ecological network scheme of the core city of Zhengzhou is reasonable,it can provide the basis for the construction of Zhengzhou City greenway construction.Finally,the paper has studied on planning level for the greenway space of Zhengzhou.From guiding ideology and principles of planning,policy guidance,planning techniques and control measures four aspects gives comprehensive construct.It is hope that makes an efforts for building the beautiful Zhengzhou,the ecological Zhengzhou and Zhengzhou harmonious living environment. |
