Research On Greenway Route Selection In Urban Shallow Mountainous Area Based On ArcGIS

Since the 21st century,after China introduced the concept of Greenway into China,China has carried out research on the concept of Greenway and excellent cases of European and American greenways.In view of the good effect of greenway network construction in the Pearl River Delta after 2010,a nationwide upsurge of greenway construction has been set off.In the 21 st century,under the background of ecological era,greenway has become an important link in series of green scattered space and a key link in the restoration of broken landscape pattern with its unique characteristics.Since 2017,the research boom has faded slightly,and the breakthrough in greenway research has transformed into in-depth research combining current hot spots and practical needs.As the transition space between plains and mountains,the unique natural and humanistic resources of urban shallow mountainous areas can be combined with greenway construction to maximize benefits.Therefore,the construction of urban shallow mountain greenways has become the focus of current research.The research on the route selection method of urban shallow mountain greenways will lay a solid foundation for the construction of shallow mountain greenways.This paper takes Hero-Qili shallow mountain area in Jinan city as the research object,using literature research method,expert scoring method,AHP analytic hierarchy process,Arc GIS spatial analysis method and empirical research method as the research method,to carry out the research of greenway route selection in Jinan shallow mountain area.Firstly,the literature research method is used to clarify the research progress of related topics,and the comprehensive route selection method combining suitability analysis,hydrological analysis and horizon analysis is innovatively proposed.The questionnaire survey and participatory research method are used to investigate the current situation of the study area.The suitability evaluation factor of greenway route selection is determined by combining the research topic with the relevant policy environment,resource elements and local willingness of Jinan.Secondly,using expert scoring method and AHP analytic hierarchy process to build a comprehensive evaluation system.Then,based on Arc GIS software,the suitability analysis,runoff simulation,watershed division and horizon analysis of each element are carried out,and the digital analysis is obtained,which provides the basis for the subsequent greenway route selection and post selection.According to the weight of the evaluation system,the three are weighted and superimposed to obtain the results of digital comprehensive analysis.Furthermore,the upper planning and existing greenways are used to empirically analyze the results of digital analysis,and the scientificity and reliability of the research are clarified.Based on the results of upper planning and digital analysis,the route selection of urban first-level and second-level greenways and community first-level and second-level greenways are carried out,and the specific location of service stations is selected.The natural,human,hydrological,sight and other factors are fully considered to optimize the final route selection and location.Finally,the research involved in the shallow mountain greenway route selection methods are summarized,and a comprehensive urban shallow mountain greenway route selection method system is obtained.
