河南省A级旅游景区时空演变特征

The Spatiotemporal Evolution of A-level Tourist Attractions in Henan Province

运用图表法和GIS空间分析技术从时空角度对河南省A级景区演变特征进行了研究.结果表明:根据图表法得出河南省景区数量增长速度快,尤其是4A和3A级景区,但景区等级结构不协调;通过最邻近指数、地理集中指数和标准椭圆分布法得出河南省A级景区分布逐步均匀化且有平均分布中心向东南方向偏移的趋势.目前,河南省豫东和豫南的旅游景区密度与其他区域相比还是较低,应加大高级别景区的发展和低级别景区向高级别景区转化的力度,以促进河南省A级景区空间布局合理,旅游业可持续发展.

Using chart method and the GIS spatial analysis technology,this study researches the evolution characters of A-level tourist attractions in Henan Province from the perspective of time and space,to provide scientifically theoretical support and practical reference for optimizing and adjusting the spatial pattern of A-level tourist attractions. Results show that the number of tourist attractions in Henan Province increases fast,especially the 4A and 3A levels, but the hierarchical structure of tourist attractions is not harmonious. A-level tourist attractions in Henan Province distribute uniformly and the average distribution center gradually offset to the southeast direction by means of nearest neighbor index,geographic concentration index and the standard deviation ellipse. But at present the density of tourist attractions in the eastern and southern of Henan Province is higher than other regions. Henan Province should step up the development of high level tourist attractions and the low level to high level,and still need to improve the support to those area,in order that A-evel tourist attractions distribute reasonably and the tourism industry develops in a rapid and effective way.
