摘要
自然旅游资源是指由地质作用形成的具旅游价值的自然景观和自然环境,其空间分布特征与影响因素的研究是现今研究的热点之一。九龙县位于川滇南北构造带北段西侧,区内自然旅游资源类型丰富、特征明显。选取九龙县为研究对象,利用Arc GIS软件对区内自然旅游资源进行最近邻指数(R)与核密度分析,结合叠加分析与数理统计探讨其分布特征及其与地形地貌、坡度坡向、地质构造等影响因素间的相关性,总结其空间分布特征和影响因素。结果表明:九龙县中自然旅游资源空间分布差异显著,R=0.276<1,表现为聚类特征,自然旅游资源总体呈现“北西部及南部多,东西部少”的分布格局,主要受地形地貌、地质构造、河流分布与交通影响。该成果对国土空间规划及旅游资源开发保护提供了科学依据。
Natural tourism resources refer to the natural landscapes and natural environments with tourism value formed by geological processes.The study of their spatial distribution characteristics and influencing factors is one of the hot directions in the current research.Jiulong County is located on the west side of the northern section of the Sichuan-Yunnan North-South Tectonic Belt,with rich types of natural tourism resources and obvious characteristics.Taking Jiulong County as the research object,and ArcGIS software was used to analyze the nearest neighbor index(R)and kernel density of the natural tourism resources in the region.By combining superposition analysis and mathematical statistics,the distribution characteristics and the correlation between the natural tourism resources and the influencing factors such as topography,slope direction and geological structure were discussed,and the spatial distribution characteristics and influencing factors were summarized.The results show that there is a significant difference in the spatial distribution of natural tourism resources in Jiulong County,R=0.276<1,showing a clustering feature.The overall distribution pattern of natural tourism resources is"more in the north and south,less in the east and west",which is mainly affected by topography,geological structure,river distribution and traffic.The results provide scientific basis for national space planning and tourism resources development and protection.
