西部山区城市山地旅游资源空间结构研究——以六盘水市为例

Analysis of Spatial Structure of Mountain Tourism Resources in Western Mountainous Cities——Take Liupanshui as an Example

选取六盘水市72个山地旅游资源单体为样本,利用最邻近点指数、Voronoi多边形面积变异系数、密度分析、图层叠加分析等方法和GIS空间分析工具,对六盘水市山地旅游资源空间结构特征进行分析。结果表明:六盘水市山地旅游资源为集聚型且表现出空间不均衡性;空间分布具有明显的空间聚集性,形成了三个高密度集聚区、四个次级高密度聚集区和三条"珠串"状密集带,与交通网络、山脉和河(峡)谷分布具有一致性。

Based on the characteristics of tourism resources in Liupanshui,the research object is selecting72 mountain tourism spots altogether in Liupanshui. This paper conducted a thorough analysis on the spatialstructure features of mountain tourism resources including the K-Nearest Neighbors algorithm, Voronoi polygonarea coefficient of variation, kernel density analysis and map layer overlapping analysis, and spatial analysistools such as GIS. The result shows that though distributed randomly and uniformly, these mountain tourism re-sources were showing a trend of aggregated distribution as well as spatial imbalance. The spatial distribution ofmountain tourism resources in Liupanshui has obvious spatial agglomeration. The aggregated distribution wasmanifested as three high-density aggregation circles, four secondary high-density aggregation circles and three"pearl string"strip tourism resource intensive belt zone. Moreover, the spatial distribution of mountain tourismresources and traffic network concentrated areas, mountain ranges and river(gorge) Valley distributions showthe consistency of geographical distribution.
