| The spatial distribution of tourism has a profound impact on the efficiency of tourism industry and the degree of geographic correlation.The urban transportation network constitutes the basic spatial framework of the tourism industry layout.By exploring the spatial distribution characteristics of tourism industry and the accessibility of tourism transportation,it can reveal the overall spatial pattern of tourism under the urban scale.This article is guided by the first law of geography,core-marginal theory and accessibility theory.On the basis of establishing a POI classification system for tourism in Hangzhou’s main urban area,and using literature research,nearest neighbor index analysis,Gini coefficient analysis,kernel density analysis,accessibility analysis,and correlation analysis methods to expand the spatial pattern of tourism in the main urban area of Hangzhou Research.The main results are as follows:(1)In terms of the spatial distribution types of tourism POI,the overall spatial distribution of tourism POIs in the main urban area is cohesive,and most types of POIs in various urban areas are cohesive.POI of tourism trips,tourism-related industries and integrated services show a uniform distribution in the Binjiang area;(2)In terms of spatial distribution equilibrium overall POI of the tourism industry and the POI of the tourism and catering category is a very even distribution.POI factors for tourism accommodation,travel,tourism shopping,tourism and entertainment,tourism-related industries and comprehensive services are evenly distributed.Tourist tour is relatively reasonable for the distribution equilibrium;(3)In terms of nuclear density distribution,the overall POI,tourism catering,tourism travel,tourism shopping,tourism and entertainment POI distribution forms in the tourism industry have formed an "inverted triangle" and "horizontal" spatial distribution pattern.The last four types of POI have a "shaping" effect on the overall POI distribution.The distribution state of higher-level kernel density in the overall POI also appeared as a "multi-core,small-dispersion" spreading state;(4)In terms of accessibility analysis,the overall POI distribution of the tourism industry has a high degree of spatial coupling with the road network.Areas with poor accessibility are the barriers of mountains,waters,farmland and old airports.The overall POI basically forms a "one-hour tourist circle".Except for tourism related industries and integrated service types,the accessibility distribution patterns of other categories are similar to the overall accessibility.Tourism travel has the best average accessibility.Tourism-related industries andintegrated services have the worst average accessibility.Except for tourism-related industries and comprehensive service categories,other categories of POIs accounted for more than 90% of the main urban area in the "one-hour tourism circle" area.Through the correlation analysis of the average accessibility of each district and the number of POI distributions,it is found that the layout of the tourism industry in the main urban area of Hangzhou is largely guided by the distribution of the traffic network;(5)In terms of relevant influencing factors,the correlation between the GDP of each urban area and the distribution of tourism is relatively small.There is a certain degree of positive correlation between the output value of the tertiary industry and the distribution of tourism.The correlation between the per capita GDP index and the distribution of tourism shows a negative correlation.There is a strong positive correlation between the population and the distribution of POI.There is a strong negative correlation between population density and the distribution of tourism POI.The distribution of tourism POI has a significant positive correlation with the size of each urban area.Through a summary analysis,this paper proposes relevant optimization strategies for the spatial pattern of tourism in the main urban area of Hangzhou. |
