河南省高等级旅游景区空间结构分析

Analysis of spatial structure of height class tourism attractions in Henan province

运用数据分析和ARCGIS空间分析方法,以差异度、集聚度、连接度和通达度为核心对河南省148处高等级旅游景区进行分析,结果显示河南省高等级旅游景区空间上呈现显著聚类分布,黄河沿岸的郑汴洛三门峡,西北部的太行山脉,南部的伏牛山脉是高等级旅游景区的聚集区;α指数=0.296,β指数=1.586、γ指数=0.544,说明旅游网络回路性较差,连通性一般,呈简单环网状;通达度指数的平均值是249.304 km,平均路经长的平均值是5.044,通达性较好的区域主要集中在中部的城市群,外围区域通达性普遍较差.紧密度指数=0.755,全省紧凑程度处于中上等,为发展交通提高旅游网络的通达性提供了良好的先天条件.

Using mathematical statistics and ARCGIS spatial analysis methods,the analysis of 148 high-level tourist attractions in Henan province based on the degree of difference,agglomeration degree,connectivity and accessibility shows that the high-grade tourist attractions in Henan province have a significant cluster distribution,the Sanmenxia area along the Yellow River,the Taihang mountains area in the northwest,and the Funiu Mountain area in the south are the gathering areas for high-grade tourist attractions;the alpha index=0.296,the beta index=1.586,and the gamma index=0.544,indicating that the tourism network is poorly circuitous and has a poor connectivity.It is a simple ring network;the average accessibility index is 249.304 km,and the average road length is 5.044.The areas with good accessibility are mainly concentrated in the central Zhengzhou,Xuchang,Pingdingshan,and Weihe Rivers,peripheral accessibility is generally poor.The tightness index is 0.755.The degree of compactness in the province is in the middle and upper grade,providing good conditions for the development of transportation to improve the accessibility of the tourism network.
