Tourism Resources Evaluation And Spatial Pattern Analysis Of Lijiang River Basin Based On Multi-source Data

Cloud computing,Internet of things and other big data era have flooded into people's lives,which not only profoundly changed the way of life of the public,but also brought a significant impact on the research field.The data of network information is easy to obtain,with large sample size and wide source distribution.Therefore,with the help of Internet and information technology,tourism resource attribute data can be obtained in large quantities,which can be combined with traditional data source attribute indexes,and provide new ideas and methods for tourism resource evaluation research.This paper takes Lijiang River Basin as the research area,obtains all tourism resources evaluation objects and new data source attribute indexes by manual collection,And using the analytic hierarchy process and entropy method to build a comprehensive evaluation system of tourism resources to carry out corresponding evaluation.On the basis of evaluation,Using standard deviation ellipse,spatial autocorrelation analysis,kernel density analysis and other methods to analyze tourism resources of Lijiang River Basin.Finally,some suggestions are put forward to optimize the spatial pattern of tourism resources in the study area.The main findings are as follows:(1)There are 369 valid tourism resource points in Lijiang River Basin,which are divided into 3 main categories,16 sub categories and 89 basic categories.The number of leisure activities and human landscape is 141,significantly more than that of natural landscape(87).In terms of the number of resource categories,Yangshuo County has the most abundant tourism resource composition,followed by Lingui District,while Diecai District and Pingle county have a single tourism resource.The comprehensive evaluation value of natural landscape in Lijiang River Basin is the highest,followed by leisure activities,and the attraction of human landscape is the lowest.In terms of subcategories,the ranking of tourism resources comprehensive score is the same as that of the top three categories,and the ranking of resources,environment and development conditions is consistent with the actual situation.According to the scores of resource points,Xijie,Lijiang scenic spot,Xiangshan scenic spot and Yulong River have the highest evaluation values.(2)Based on the exploratory analysis of the spatial pattern of tourism resources in Lijiang River Basin,it is found that the distribution direction of tourism resources points in the study area is northeast southwest,and its spatial distribution center is located near the urban area of Lijiang River basin to Yangshuo section,and with the increase of distance from Lijiang River,the spatial concentration of tourism resources points begins to decrease.The weighted tourism resources show a southward migration,indicating that the comprehensive evaluation value of various tourism resources in the south of Lijiang River Basin(Yangshuo County)is higher than other regions as a whole.The spatial distribution characteristics of different types of tourism resources are different due to the scores of four influencing factors: comprehensive evaluation,resource attraction condition,resource environment condition and resource development condition.Among them,the aggregation characteristic of resource attraction condition score is the least obvious,which is related to the data from tourism websites,while the aggregation characteristic of resource environment condition score is highly obvious,which is the number of subjects According to the impact.From the analysis of spatial core density,it is found that the spatial distribution of all kinds of tourism resources has the characteristics of aggregation,and there are similarities and differences in the areas of attraction intensity,and the spatial distribution patterns of the three types of tourism resources all present two cores,namely four main urban areas(Diecai,Xiufeng,Qixing,Xiangshan)and Yangshuo County.Finally,according to the types,characteristics,spatial distribution characteristics and traffic conditions of the tourism resources in the study area,it is suggested that promoting the balanced development of resources,coordinating the coordinated development,elaborately designing cross regional tourism routes,enhancing regional cooperation,digging deep into the tourism resources in the area around the city,expanding the tourism circle of Guilin,actively building tourism scenic spots,and strengthening the core radiation attraction.so as to promote the healthy and sustainable development of the tourism industry in the Lijiang River Basin.
