摘要
在区域范围的城市旅游体系中,引入"中心地的中心性"概念,可以在这种旅游性的空间网络中考察城市地位的相对重要性,划分出城市的等级层次,判断出不同级别的中心城市,更可以进一步得到区域空间的城市旅游构成关系。Voronoi图在地理学中是一种利用中心地的中心性广泛用于空间分割、空间邻域查找的空间剖分方法。引入这种方法,以苏浙沪地区为例,在25个地级以上城市中,利用Voronoi图的空间分割原理,找出不仅具有规模性,而且具有空间组织功能的旅游中心城市。
The centricity of heartland is very important to the regional tourism. It is useful for judging the city＇s station, rating in the regional tourism area. Voronoi diagram is the way of spatial subdivision or spatial neighborhood finding in geography research. The article takes twenty-five municipalities in the regions of Su-Zhe-Hu for instance. Firstly, it calculates these twenty-five municipalities＇ centricity index. Secondly, on the base of twentyfive centricity index, it adopts Voronoi diagram＇ s spatial subdivision to find three levels central tourism city in the regions of Su-Zhe-Hu, which not only have scale function but also have spatial organizing function.
