东北地区A级旅游景区空间分布特征及影响因素

基于东北地区2009年、2012年和2015年A级旅游景区数据,采用最邻近指数、基尼系数、核密度分析、相关分析等数理和空间分析方法,基于GIS空间分析技术,从类型、均衡度和密度等方面对东北地区A级旅游景区的空间分布特征及影响因素进行研究,结果显示：① 2009年、2012年、2015年3个时段,东北地区A级旅游景区在空间上呈集聚状态,且集聚程度具有先强后弱的演变特征;② 省会城市和主要交通节点城市附近A级旅游景区核密度较大;③ 随着旅游业的快速发展,东北三省A级旅游景区核密度增强区域扩散较快,但蒙东地区变化较慢;④ 旅游资源空间分布受自然因素和人文因素影响很大,其中地形地貌、水文是影响A级旅游景区分布的内生因素,而社会经济水平、交通等是重要的外推动力,对A级旅游景区分布影响比较显著。

Spatial Distribution and Its Influencing Factors of Level-A Scenic Spots in Northeast China

Based on the Northeast China’s data of level-A scenic spots in 2009, 2012 and 2015,using the nearest neighbor index, Gini coefficient, kernel density analysis, correlation analysis and other mathematical and spatial analysis methods, and based on GIS spatial analysis technology, this article studies the spatial distribution characteristics and influencing factors of level-A scenic spots in Northeast China from the aspects of type, equilibrium degree and density. The results showed that: In 2009, 2012 and 2015, level-A scenic spots in Northeast China show a agglomeration state in the spatial, and the degree of agglomeration has the characteristics of first strong and then weak. The provincial capital cities and main traffic nodes near the city have larger Nuclear Density of level-A scenic spots. With the rapid development of the tourism, the proliferation of kernel density of level-A scenic spots in Northeast China is faster, but that in eastern Inner Mongolia is changing slowly. The spatial distribution of tourism resources is greatly influenced by natural and cultural factors, topography and hydrology are important factors affecting the distribution of level-A scenic spots. On the social-economic aspect, traffic and other factors are very important power of extrapolation, and have significant influence of the distribution of level-A scenic spots.
