江苏省A级旅游景点空间格局与影响因素

Spatial Patterns and Influencing Factors of A-Level Tourist Attractions in Jiangsu Province

基于GIS空间分析技术,采用最邻近指数、标准差椭圆和核密度分析法探究了江苏省544个A级旅游景点的空间分布特征以及影响A级旅游景点空间格局的自然和社会因素.研究结果表明:受资源禀赋、地形水文等自然地理要素和地区生产总值、交通系统、人口密度等社会经济要素的影响,江苏省A级旅游景点空间分布热点和密度差异较为明显,呈现出“南部多且密、北部少且散”的空间格局;江苏省A级旅游景点属于集聚型,在旅游景点的级别上形成了橄榄形结构;江苏省A级旅游景点标准差椭圆长轴方向为西北—东南,空间中心在扬州市高邮市.

Based on GIS spatial analysis technology,this paper explored the spatial distribution characteristics of 544 A-level tourist attractions in Jiangsu Province and the natural and social factors affecting the spatial pattern by using the nearest neighbor index,standard deviation ellipse,and kernel density analysis.The result shows that natural geographic factors such as resource endowment,topography and hydrology,and socio-economic factors such as gross regional product,transportation system and population density,affect the spatial distribution of A-level tourist attractions in Jiangsu Province,and the spatial distribution presents a spatial pattern of“more and dense attractions in the south,less and scattered attractions in the north”.The result also shows that A-level tourist attractions are clustered,and they form an olive-shaped structure at the level of tourist attractions.And the result reveals that the long axis of the ellipse of standard deviation of these tourist attractions is in northwest-southeast direction,and the spatial center lies in Gaoyou of Yangzhou City.
