| 摘 要： | 本文以南京市旅游景区（点）系统为例，采用测算与分析空间关联分形维数的方法对景区（点）系统的空间结构进行了研究。根据旅游景区（点）系统空间结构的无标度特性和遵循的进化过程，认为对其空间结构进行分形研究是可行的。南京市景区（点）系统的空间结构是分形的，具有景点系统空间结构演化自组织优化的趋势，在地理区域分布上表现为景点空间分布较集中的特性。同时认为景区（点）系统空间结构具有自仿射性分形特征，景点系统从中心向外围有递变的趋势，且在不同方向上递变的比率是不同的，在地理区域上表现为景点的空间分布越往外围越集中（或均衡），且不同方向上的集中性程度是不同的；具体到南京市来说是递减的，向南部递减的较慢，向北部递减的较快。同时系统的空间结构也基本具有分形对称性特征。

| Abstract: | Using the method of correlation dimension, this paper has studied spatial structure of tourist scenic spots systems in Nanjing. The tourist spots systems are in chaos, and their evolution tendency is driven by strange attractors. Strange attractors are featured as non-integer dimension and infinite nested self-similarity structure, those characters make the fractal method a optimum one to study the structure of tourist spots systems. The fractals are non-scaling and self-organization, and the fractals carry natural optimized structure. The structure of tourist spots system has the character of the fractals, it is therefore feasible to apply the fractal methods for the analysis of the structure of the system.
According to geographical character and the tourist spots systems in Nanjing, the author has classified the tourist systems into three parts, namely the northern tourist scenic spots systems, the southern tourist scenic spots systems and the middle tourist scenic spots systems, and has measured the value of correlation fractal dimension of each systems, and analyzed and explained the spatial structure of the systems.
It is found that the spatial structure of tourist scenic spots systems in Nanjing is fractal, and it behaves the character of Self-affine Fractal, the spots are aggregated in spatial distributing. The spatial structure of the systems follows the role of the Brown Motion during its evolution process. And the spot systems vary from the center to circumference with different rate at different directions. For instance, the values of correlation fractal dimension are decreasing form the center to circumference, and decreasing rate in the northern tourist scenic spots systems is faster than that in the southern, Furthermore, the fractal of the spatial structure of the systems is quasi-symmetry among different hierarchies, and they are approximately self-similar. |
