Planning Of Greenway System In Yilan County Based On Suitability Evaluation

Urban greenway planning and design can integrate the existing landscape resources of the city effectively and have some effects on urban greenland system restoration,ecological environment protection,historical heritage and regional coordinated development.Apart from that,greenway can also promote the development of regional economy and society and the construction of the landscape pattern.Compared with the plain area,Yilan County has rich landscape resources with a greater variety of ecological environment.But also because of this,the ecological environment in Yilan County is more ecologically sensitive and will be difficult to resume once it damaged.Therefore,Yilan County need to search for a way to protect the status of the landscape resources urgently.Greenways will not only improve the space environment,but also create a place suitable for leisure and recreation.In addition,the open linear space in Yilan County such as mountains and waterways can integrate and utilize these resources,reflecting the geographical features of Yilan County and unique landscape pattern.In sum mary,Yilan county greenway system planning and construction has great significance.Based on the county range of Yilan County identified in the Yilan County Urban Master Plan(2011-2030),this study adopts the methods of suitability analysis,AHP(Analytic Hierarchy Process),GIS data analysis and processing,literature research,research method,comparative research method,inductive summary method and so on to study the route selection and final layout of Yilan county greenway system.The dissertation firstly analyzes the background,purpose and significance of the research,as well as the analysis of the research results in relevant fields both at home and abroad.It also summarizes the research content,organizes the research framework and illustrates the feasibility of the research.Paper chooselandscape ecology,landscape connectivity theory,buffer theory and other related theories as the research support,laying a solid foundation for the preliminary study of Yilan county greenway system planning,but also as the Yilan county greenway alignment technical basis.Analysis the status quo of Yilan County based on the construction of the greenway,this paper chooses the advanced feature of the selected route elements and chooses the suitability evaluation system of greenway route selection of Yilan County through the analytic hierarchy process.At last,GIS spatial superposition method is applied to superpose each analysis result to get the result of line selection of Yilan county greenway system based on suitability evaluation.In addition,the basic conditions in Yilan County are also the influencing factors for the construction of greenway in the county.Therefore,these results should be amended.Based on this,the spatial distribution and grade structu re of greenway in Yilan County are planned,and then the classification and design of greenway are classified according to the characteristics of each greenway.Finally,the planning and design of greenway facilities will be finished.
