运用GIS软件的空间分析功能,对河南省5A和4A旅游景区的空间分布进行了分析。首先以河南省各省辖市为主要旅游城市,建立点缓冲区,分析以各省辖市为驻足地进行旅游的旅游景区分布信息及可达景点的空间距离;然后以河南省主要国道干线为基轴线,建立线缓冲区,分析旅游景区与国道的关系,为自驾车旅游者提供可达景点的空间信息;最后结合基于点、线的缓冲区分析,总结了该地区旅游景区沿国道密集分布的线状特征与以城市为中心密集分布的点状特征相结合的特征,为旅游者选择线路提供参考,为政府决策提供科学依据。

This paper used the spatial analysis function of GIS to analysis the spatial distribution of 5A and 4A class tourist attractions in Henan Province. First of all, taking each cities in Henan Province as the main tourist city, the paper established a point buffer, and analyzed the distribution information of the various municipalities to tourism scenic spots and could reach spots space distance. And then, taking the national roads in Henan Province as the basic shaft lines, the paper established a line buffer, and analyzed the relationship between tourism scenic area and the national roads. Finally, combining with the point and line buffer, the paper summarized the characteristics that the combination of along the national road density distribution linear features and distribution in the city centered point features in Henan Province's tourist attractions. This study can provide some references for the tourists choose lines, and the basis for government decision-making.
