Calculation Method Of Landscape Beauty Of Linear Tourism Unit Based On GIS And Photo Content Analysis

At present,China's tourism industry is ushering in an important period of transition from focusing on quantity to focusing on quality.At the same time,with the popularization of private cars and the improvement of traffic conditions,self-driving travel has become one of the main travel methods in the era of global tourism.Rapid development.However,the backward development and management of landscape resources in linear tourism units are difficult to meet the increasing tourism experience needs of tourists,and the rational development of their tourism resources has become an urgent problem to be solved by tourism planners.But at present,there is a lack of research on landscape planning and design of linear tourism units.In order to provide tourists with an unforgettable and in-depth experience tour during the travel process,the transportation process during travel is transformed into a deep travel experience for tourists,and the landscape content and tourists who can perceive the tourist at different locations can be obtained The landscape preference is indispensable,according to which we can better realize the scientific management of landscape resources and enhance the goal of tourists 'viewing experience.This article uses various methods to achieve the quantitative calculation of landscape beauty with the support of geographic information system(GIS)spatial analysis tools and social media photo data.First,the article analyzes the concepts of "linear tourism unit","landscape",and "landscape beauty",and sorts out related research progress.On this basis,it constructs a spatial factor,topographic factor,and landscape content.The landscape aesthetic spatial perception system composed of factors and landscape structure factors,each of which is composed of several indicators.Based on the landscape aesthetic space system,in the ArcGIS software platform,using the tools of visual field analysis,spatial statistics,ArcPy and other tools to achieve the quantitative calculation of all landscape single factors.Then use the photo content analysis method,entropy weight method and other research methods to judge the tourists' landscape preferences for different landscape types,and then build a calculation formula for the landscape beauty based on the landscape preferences and single-factor calculation results,so as to achieve all sections The spatial distribution of the scenic beauty values.Select the Tianlu Scenic Area of Hebei Grassland as the case area to conduct an empirical study.Through the visual field aggregation analysis,the visual field range that is more complete and conforms to the actual observation by the human eye is obtained.Taking the visual range on each road segment as the basic statistical unit,all single-factor calculations under the landscape aesthetic spatial perception system are completed.Use the web crawler tool to obtain travel photo data containing location information from the two-step road and six-foot website,and select high-quality landscape photos from it.First,use content analysis and aggregate image methods to interpret the tourists 'interest.Landscape combination,and then obtain the grade distribution of various landscape type photos on each landscape factor by setting the landscape photo aesthetic quantitative evaluation rules,and use the entropy weight method to calculate the weight of various landscape type aesthetic perception factors,and finally construct the landscape beauty Degree calculation formula,and calculate the distribution of the beauty degree values of various landscape types on all road sections.The main contribution and innovation of the paper are:(1)Use social media photo data to obtain tourists' landscape preferences,and use the entropy weight method to determine the weight of factors,to avoid research errors caused by subjective weighting,and to strengthen the objectivity of the research Sex and science.(2)Constructed a full calculation method of landscape beauty based on landscape type,so as to improve the refinement of the calculation results(3)Use photo content analysis and GIS spatial analysis to fully integrate the tourism planning and development of linear tourism unit units and improve Tourists' aesthetic feelings of landscape are of great significance.
