西成高铁沿线区域A级景区空间点格局研究

Analysis on the Spatial Point Pattern of A-grade Scenic Spots in the Area along Xi′an-Chengdu High-speed Rail

通过获取西成高铁沿线8个市级行政区A级景区和高铁站点的地理坐标,利用核密度估计、Ripley′sK函数等方法进行空间点格局分析。结果表明:①西成高铁沿线景区形成了以成都、西安为中心的双热区分布和由成都向乐山、绵阳辐射的次热区分布。②人文遗址类和自然遗迹类景区分别在65km和75km左右的范围内呈聚集分布,现代人造或重建类景区则一直呈聚集分布。③88.4%的景区分布在8个中心城市的“一日游”圈内。

Taking Xi′an-Chengdu HSR as an example,and using the geographic coordinates of all A-grade scenic spots and high-speed rail stations in eight municipal-level regions along the HSR,this paper analyzed the spatial point pattern with the application of kernel density estimation and Ripley′s K function.The result showed that:①the scenic spots along the HSR forms the double-hotspot distribution centered in Chengdu and Xi′an and the sub-hotspot distribution radiating from Chengdu to Leshan and Mianyang.②Scenic spots of cultural sites and natural relics were distributed in an aggregated way within areas of which diameters were some 65 and 75 kilometers respectively.Scenic spots which were artificial or rebuilt ones are of highly aggregated distribution.③88.4%of the spots located within the one-day tour circles of 8 central cities.
