Research On Visualization And Model Of Shadow Shading In Tourist Destinations

The shadow of tourism is a ubiquitous objective phenomenon.The effect of shadows in tourist destinations can also be clearly reflected in people's subjective images.However,the objective spatial representation of shadows in tourist destinations is difficult to visualize or quantify.Therefore,studying the types,effects and spatial characteristics of shadow shading in tourist destinations has positive significance for the construction of shadow shading theory of tourism destinations,as well as the sustainable operation and coordinated development of tourism destinations.Guided by central theory,location theory,growth pole theory and niche theory,the thesis uses linear weighted summation,weighted Voronoi,nuclear density analysis,standard deviation ellipse and other methods from the perspective of tourism object,namely tourism destination.The shadows,visualizations,features,effects and patterns of the world heritage and A-level scenic spots in Jiangsu Province.Studies have shown that China's World Heritage category is complete and abundant,with a focus on world cultural heritage.In terms of space,it is mainly distributed in North China,Southwest China and Central China.There are four provincial-level administrative regions with no World Heritage.In terms of quantity,1987-2002 is the pre-existing period,and in 2002-2018,it is the late period.Less" and the characteristics of the middle fault.China's tourist attractions above 3A level show a mass or patchy distribution,and the regional distribution is obviously different.In terms of quantity and grade,there are more distributions in the eastern and central regions,and less distribution in the western regions.The distribution of tourist attractions and world heritage sites is concentrated in the eastern region.The essence of shadows in tourist destinations is the market competition between tourist attractions or heritage sites,which is mainly reflected in the interaction and interaction between tourism demand,tourism supply,regional background and tourism environment,namely tourism subject and tourist object.The influence and role of tourism carriers and tourism mediators.The essence of competition is the game between different tourism supply and comprehensive influence value.The strong and weak tourist attractions will have different influence ranges,and the spatial relationship of the scope is the direct expression of shadow shading.Shadows of tourist destinations are universal,dependent and spatially transformative.The distribution of world heritage and scenic spots in Jiangsu Province is extremely uneven,showing three gradients.By referring to the gravitational correction model and the influence of tourist attractions,the maximum carrying capacity of the scenic spot,the traffic accessibility,the time and space distance and other related indicators,the entropy method is used to measure the index weights,and the weighted Voronoi diagram is used to make the world of Jiangsu Province The shades of the tourist sites in the heritage and A-level scenic spots are visualized.In general,the degree of shadow shading is the highest in southern Jiangsu,followed by Northern Jiangsu,and the weakest in Suzhong.The level of the tourist destination is positively related to the extent of its formation.Outliers in the shadow range often appear in low-level scenic spots.The masking radius decreases with the level of the scenic spot.The lower the level,the smaller the radius gap.The shading radius of the World Heritage Site is twice the shadow radius of the 5A-level tourist scenic spot,and the shadow shading radius of the 5A-level tourist scenic spot is twice the shadow shading radius of the 4A-level tourist scenic spot;the shadow shading radius of the 4A-class tourist scenic spot is generally greater than the 3A-level tourist The shadow of the scenic area shades the radius,but the difference between the two is small.The shadow relationship presents a multi-level nesting feature of "large cover,high cover".The greater the density of the regional scenic spots,the wider the shadow of the tourist destination.Administrative divisions have a weaker impact on the shadows of tourist destinations.The shades of tourist destinations are divided into three types: full-shadow,semi-shadow and non-shadow;in the tourist attractions,tourists and tourist destinations,they are divided into resource elements,location conditions and tourist image;From the number of tourist sites,there are three types: single masking,single multi-body shielding and multi-body shielding.The shading of tourist spots in Jiangsu Province has a plaque shading mode,a corridor shading mode and a nested shading mode.The study on the causes of shadow shading in Jiangsu Province shows that shadow shading is the result of competition and spatial representation of tourist source market.Time and space distance and relative geographical position are objective conditions for shadow shading.The preference and characteristics of tourism subject are tourism.The subjective conditions caused by the shadow of the earth;the attraction of the tourist object is the basic driving force for the shadow of the tourist destination;the profitability of the tourism mediator enhances the shadow shadowing effect of the tourist site.
