长江经济带游憩资源空间分布及影响因素分析

On Spatial Distribution and Influencing Factors of Recreational Resources in the Yangtze River Economic Belt

运用ArcGIS核密度、标准差椭圆、最邻近值等分析方法和兴趣点数据研究长江经济带游憩资源空间分布的差异特征,并从地形地貌、交通、人口密度、社会经济水平等对游憩资源空间分布的相关影响因素进行探究,以期为建设美丽宜居城市提供理论依据和决策参考。结果表明:(1)长江经济带区域内游憩资源呈现聚集型分布;(2)游憩资源空间分布密度存在差异性,在长江经济带上游、中游、下游三大区域中呈现不均衡分布;在长江经济带流域内四川省、江苏省游憩资源数量占优,湖北、湖南两省游憩资源密度较高,四川、云南、贵州三省游憩资源空间分布比较分散;(3)游憩资源的空间分布方向呈现出东北—西南走向;(4)地形地貌、交通网络、社会经济发展对游憩资源空间分布影响较大。

Using the analysis methods of ArcGIS nuclear density,standard deviational ellipse,as well as the nearest neighbor value and Point of Interest data,this paper studied the differences of the spatial distribution of recreational resources in the Yangtze River economic belt,and explored the related influencing factors of the spatial distribution of recreational resources from topography,transportation,population density and socio-economic level,in the hope of providing a theoretical basis and decisionmaking reference for the construction of a beautiful and livable city.The results were shown as follows:(1)the spatial pattern of recreational resources in the Yangtze River economic belt was of aggregated;(2)there were some differences on the spatial distribution density of recreational resources,showing an unbalanced distribution in the upper,middle and lower reaches of the Yangtze River economic belt;the recreational resources in Sichuan and Jiangsu Provinces were dominate in number;the recreational resources in Hubei and Hunan Provinces had a higher density;the spatial distribution of recreational resources in Sichuan,Yunnan and Guizhou Provinces was relatively scattered;(3)the spatial distribution direction of recreational resources was from northeast to southwest;(4)transportation network and social-economic development had great influence on the spatial distribution of recreational resources.
