Study On Greenway Plan And Route Selection For Nanning Qingxiushan Scenic Area

Greenway is an important infrastructure of scenic area, is a great natural features, ecological value and multifunctional concentrated linear open space, is a kind of effective way to ease and improve the related environmental problems. However, the subjectivity of the traditional methods of the greenway planning for a strong, the accuracy is not high and low effectiveness of generality. Along with the rapid development of computer technology and geographic information system (GIS) is becoming more and more perfect and widely used, for the application of GIS in the scenic spot of greenway line selection construction provides the technical support, for the construction of the scenic spot of the greenway has scientific significance.Select greenway route selection for Nanning Qingxiushan Scenic Area as the study object, based on GIS spatial analysis, choose the greenway concept of impact factor, and combined with analytic hierarchy process (AHP) and rank given factor weights assignment method, For scenic spot of the greenway lines based on GIS, realize the scenic spot of greenway line selection of quantitative study, discusses the GIS application in the scenic spot of the greenway planning method. The main study results as follows:(1) The study of stocktaking greenway related concepts and study abroad, analyses the existing problems and the insufficiency. In fully discussed, on the basis of the study area, using GIS and related software to analyze it, established a research area of digital elevation model, attractions of digitalization, drainage factor and vegetation factor related to the database.(2) According to the actual situation of the study area, through the analysis of the evaluation, slope, elevation, land types and visual sensitivity four factors as the main factors affecting the greenway line selection, Using the analytic hierarchy process (AHP) to determine the weight of each factor, four factor weights were 0.16,0.27, 0.06,0.51, and give an assignment, using the method of rating assignment score value range of 0-100, applying GIS technology weighted superposition gain Qingxiushan scenic area the greenway concept of cumulative value. According to this result, the GIS spatial analysis module cost path analysis, combined with the theory of practice to select the green Qingxiushan scenic area.(3) Based on the results of the line selection, in combination with the results of the current state of the study area, landscape resources evaluation results and site conditions of site condition five different theme tour route of five different theme tour route:visit sites route, study discussion, popular science education route line of line, the natural scenery and cultural exchange experience.The study results show that using the GIS technology to the scenic spot greenway line selection for qualitative and quantitative study, provides a more objective basis for greenway planning, improve the strategy and accuracy of the green road planning, at the same time can also be scenic area for further research to provide certain reference and reference.
