| The Scientific cognition,mining,collection,analysis and evaluation of tourism resources are not only the quality assurance of tourism resources census,but also the basic link of tourism development and tourism planning.This paper is aimed at the current evaluation method of tourism resources whcin is relatively simple,updated slowly and the research scale is susceptible to the regional area,and the gridding method based on GIS spatial analysis has less research in the field of tourism.A set of methods for gridding analysis and evaluation of tourism resources is proposed:(1)Proposing the tourism resources cognition method,mining method,classification method and collecting method.The tourism resources recognition and collection are the primary tasks of analysis,evaluation and even tourism planning.Based on the problems encountered in the survey and collection of tourism resources of Hainan,Qingdao,Penglai,this paper explores the tourism resources cognition,mining and collection from method and technology aspects:Firstly,in the aspect of method,the paper puts forward some relevant concepts for interpret tourism resources which are the component ontology,the causes of ontology,event ontology,symbiotic ontology,associated ontology and intersecting ontology based on tourism resources digging,and then analyzes the relationship between tourism resources monomer and tourism resources aggregation;Secondly,in the aspect of technical,this paper puts forward the way of digital collection tourism resources,The technology based on location service(LBS),network map and satellite image plotting,GPS mobile phone location and spatial database of the B/S framework,realized the collection of tourism resources inside and outside the industry,entry online of tourism resources attribute information,function of expert review,which is used to provide technical reference for the national tourism resources census.(2)Put forward the concept of the gridding tourism resources,construct the gridding theoretical framework and spatial fitting method.According to the spatial analysis methods of the social,economic,population data,the concept of the gridding tourism resources and the construction methods are further proposed.At the same time,the paper discussed the spatial fitting model of the gridding tourism resources,the type of the gridding tourism resources unit and the selection method of the grid size,which provide a reference for the spatial analysis and evaluation of tourism resources under fine scale.(3)Proposing a gridding classification system and quantitative identification method for tourism resources.Firstly,according to the spatial cluster effect on tourism resources,the paper proposes a three-tier classification system based on the rule grid units to classify the main categories of tourism resources clusters-sub-categories-basic classes;And then extract the distribution characteristics of tourism resources gathering areas base on the spatial distribution pattern of tourism resources;Finally,an improved neural network model is used to realize the quantitative identification of various types of tourism resource agglomeration areas through sample training,which provides a classification basis for the subsequent analysis and evaluation of tourism resources grid,and also provides a reference for the division of tourism functional areas.(4)The gridding evaluation methods and models are constructed from the perspective of subjective tourism resources and the objective development conditions of tourism resources.On the subjective aspect of tourism resources ontological gridding evaluation,firstly,the evaluation model based on the quantity,quality and type of tourism resources is improved,which transformed the traditional evaluation unit based on administrative region into the grid unit.Secondly,according to the characteristics of multi-scale transformation of grid,the improved gridding field strength model is adopted to analyze the spatial relationship of collaborative development or competitive development of various tourism resource agglomeration areas at various grid scales;In addition,considering the dynamic nature of tourism resources and the timing of evaluation,a grid-based spatial-temporal analysis database model is proposed.On the objective aspect evaluation of the tourism resources develop conditions,the grid handling evaluation is carried out from the aspects of the development environment of tourism resources and the restrictive factors.The former improves the traffic location evaluation method based on the model of time accessibility,economic cost accessibility based on the vector grid,proposes the spatialization of tourist data based on the GWR model and constructs the grid evaluation model of tourism industry POI data;The latter puts forward the weight assignment method for the combination of subjective and objective evaluation models for the multi-index evaluation of natural disaster risk and ecological safety character.(5)Case verification and analysis.The paper selected the census data of tourism resources such as Hainan province,Qingdao and Penglai city of Shandong province as the data support of the analysis method,and finally,taking Qingdao City as an example,the systematic discussion and analysis was carried.First of all,the number of tourism resources through indoor collection,mainly contain inaccessible or intangible entities is 1431,accounting for 39.09%of all tourism resources.It also realizes multi-working face efficient acquisition by outdoor collection through smartphone.Secondly,the number of five major tourism resource clusters under the 0.5km,1km,and 2km grids is identified as 2048,836,and 623 through the improved neural network method.And then based on the comprehensive gridding evaluation,obtained the spatial distribution pattern and related characteristics of various types of tourism resource clusters,as well as the"Trident" spatial development axis which is round Jiaozhou bay.The proposed method in this paper is verified,and it can also provide reference for the development of regional tourism in Qingdao. |
