A Study On The Tour Road Selecting Of Tourist Attractions Based On Multi-factor Superposition

The design of the route selection is an important basic work in scenic area planning.It is necessary to consider the terrain,vegetation,water body,culture and other factors reasonably,and meet the requirements of ecology,engineering quantity and so on.It is important to the organization of tour road selecting in scenic area planning.At present,most scenic spots in China are limited by technology and methods in the design of trail selection.The traditional design methods of field survey and experience judgment are often adopted in the work of trail selection.Along with the rapid development of science and technology and the application of geographic information system(GIS)technology,working for trails line selection provides beneficial analysis tool,using computer technology to factor weighted superposition analysis,will swim trails line selection method from qualitative to quantitative auxiliary work for line selection provides a more objective and scientific basis.On the basis of analyzing and studying the design principle of trail selection,this paper explores the method of trail selection design for scenic spot trail using GIS technology platform based on multi-factor superposition.Firstly,this paper makes a general description of the research content,introduces the background,significance and purpose of the topic,and explains the research methods and technical route of the paper.And this paper introduces the related contents of geographic information system and the influence factor of trail selection,and then combines the two,makes use of the spatial analysis module and technical means of GIS,and takes the factor weighted superposition method as the theoretical support to discuss the method and principle of scenic trail selection design.Furthermore,this paper takes the Ma Gu mountain scenic area in Nancheng,county,Fuzhou city,Jiangxi province as an example to carry out a technical detailed explanation.The process and results of applying GIS technology to multi-factor overlay analysis in scenic area for trail selection are elaborated in detail.The scientific and reasonable method of using computer method for trail selection is verified,and the following results are obtained:Through the analysis and considering the actual situation of scenic areas this paper chooses the impact factors affecting the line selection results in the case of verification.And determines the assignment classification of each impact factor by inquiring experts,with the help of analytic hierarchy process,through constructing judgment matrix to impact factor,finally this paper obtains the weight coefficient of each factor in the target layer,geographical conditions: 0.0957(grade: 0.0645,slope: 0.0216,elevation: 0.0096),natural conditions: 0.0459,land use classification: 0.1484,visual sensitivity: 0.5040,ecological sensitivity: 0.2060.Through the different weight values of each factor,the multi-factor superposition analysis is carried out,and the raster image of line selection cost that synthesizes the geographical conditions,natural conditions,land use classification,visual sensitivity,ecological sensitivity and reasonable assignment of each factor is finally generated.Basis on this,combined with the GPS data of each scenic spot,using GIS optimal path analysis technology,and through the method of computer calculation the hiking trail routes of mount magu scenic area is obtained.
