山西省A级景区空间分布特征及可达性研究

以山西省A级景区作为研究对象,采用最邻近指数、地理集中指数和核密度分析法探究了景区的空间分布特征,利用栅格成本加权距离方法对不同类别景区的可达性进行了测度,并运用空间自相关分析了县域可达性的空间关联特征。研究结果表明:(1)山西省A级景区空间分布总体表现为集聚形态,呈现"南部多而密集、北部少而分散"的格局。(2)山西省A级景区整体可达性表现一般,平均可达时间为52min,可达性分布区域差异较明显,景区在县域单元内的整体可达性分布呈集聚状态。(3)可达性热点区主要分布在太原市城区和晋中市榆次区等省中部地区,冷点区主要分布在偏关县和河曲县等省界边缘地区。

Spatial Distribution Characteristics and Accessibility of A-Level Scenic Spots in Shanxi Province

Taking the A-level scenic spot in Shanxi Province as the research object,this paper studied the spatial distribution characteristics of scenic spots by using the nearest neighbor index,geographical concentration index and nuclear density analysis method.This paper measured the accessibility of different scenic spots by the method of grid cost weighted distance,and analyzed the spatial correlation characteristics of country accessibility with spatial autocorrelation analysis.The results showed that:(1)The spatial distribution of the scenic spot was generally concentrated,presenting a pattern of more and dense in the south and less and scattered in the north.(2)The overall accessibility of the scenic spot was general,with an average reaching time of 52 min.There were obviously different in accessibility distribution,and the overall accessibility distribution of the scenic spot in the county was aggregated.(3)The hot spots of accessibility were mainly distributed in the urban area of Taiyuan City and Yuci District of Jinzhong City and other central regions of Shanxi Province,while the cold spots were mainly in the marginal areas of the boundary of the province such as Pianguan County and Hequ County.
