基于POI数据的四川省旅游资源空间分布特征及影响因素研究

Research on spatial distribution characteristics and influencing factors of tourism resources in Sichuan Province based on POI data

研究基于GIS空间分析技术,以四川省旅游资源POI等地理信息数据作为研究对象,通过核密度算法、标准差椭圆、空间自相关等空间分析方法来识别各类旅游资源的空间分布特征,并从自然和人文两大因素探究分布格局形成的影响因素。结果显示:(1)四川省各类旅游资源空间集聚分布特征明显并表现出由中心向四周递减的层级趋势,总体呈现东多西少的分布格局,主要分布于成都市、德阳市、雅安市。(2)各类型旅游资源空间分布方向与景点类型分布特征吻合,现代人文类旅游资源的方向性和向心性均不明显,其余4类旅游资源的方向性和向心性均有不同程度的集聚特征。(3)各地市旅游资源分布的冷热点区域空间差异明显,生物景观类旅游资源分布较为均匀,地文景观类旅游资源在市域内热点区域最多,水域风光和现代人文景观类旅游资源的冷热点在地区分布特征上具有相似性。(4)从自然条件和社会经济条件两方面分析其影响因素,其中地形、水文是影响四川省各类旅游景区分布的内在决定力量,而社会经济水平、交通条件和人口是影响旅游景区开发建设的重要外在推力。

Based on GIS spatial analysis technology,the geographical information data such as tourism resources POI in Sichuan Province were takend as the research object,and the spatial distribution characteristics of various tourism resources were identified by spatial analysis methods such as kernel density algorithm,standard deviation ellipse,spatial autocorrelation,and the influencing factors of the formation of distribution patterns were explored from two major factors of nature and humanity.The results showed that:(1)The spatial agglomeration distribution characteristics of various tourism resources in Sichuan Province were obvious and showed a hierarchical trend of decreasing from the center to the surrounding areas,with an overall distribution pattern of more in the east and less in the west,mainly distributed in Chengdu City,Deyang City,and Ya'an City.(2)The spatial distribution direction of various types of tourism resources was consistent with the distribution characteristics of scenic spots.The directionality and centripetal orientation of modern humanistic tourism resources were not obvious,while the directionality and centripetal orientation of the other four types of tourism resources had varying degrees of agglomeration characteristics.(3)There were significant spatial differences in the distribution of cold and hot spots in various cities'tourism resources.The distribution of biological landscape tourism resources was relatively uniform,and the geographical landscape tourism resources were the most abundant in the hot spots within the city.The cold and hot spots of water scenery and modern cultural landscape tourism resources had similarities in regional distribution characteristics.(4)This paper analyzed the influencing factors from two aspects:natural conditions and socio-economic conditions.Among them,topography and hydrology were the internal decisive forces affecting the distribution of various tourist attraction in Sichuan Province,while socio-economic level,traffic conditions and population were the important external forces influencing the development and construction of tourist attractions.
