摘　　要：根据旅游景区(点)系统自组织演化的特征,以南京市旅游景区(点)系统为例,采用随机聚集分形的方法对其空间结构进行了研究。认为景区(点)系统的演化类似于有限扩散集团凝聚模型,得出景区(点)系统空间结构是分形的,具有比较明显的随机聚集分形结构,在不同的地理区域上表现为不同的系统演化时段,空间结构上的向心性作用也有强弱之分,从系统的聚集中心向四周是景点密度衰减的。指出随机聚集维数的测算与分析是景区(点)系统空间结构自组织优化趋势的判据,同时提供了优化的途径。Applying the theory and methods of random aggregation fractal,this paper studies the spatial structure of the tourist scenic spots systems in Nanjing.The fractals present non-scaling and self-organization,and bear natural optimized structure;because the fractals present nonscaling,the random aggregation dimension is the characteristic parameter to measure the fractals. The evolution tendency of the tourist scenic spots systems is similar to Diffusion-Limited Cluster Aggregation mode.Based on the definition of Diffusion-Limited Cluster Aggregation,the author puts forward the method of random aggregation fractal to study the spatial structure of the tourist scenic spots systems.The tourist scenic spots systems＇ spatial structure present distinct random aggregated fractal structure and shows a self-organization optimized evolutive tendency,but there are different evolvement phases in different regions,accordingly.The degrees of tourist scenic spots systems＇ centripetence are different and all the systems＇ stourist scenic spots densities are degenerating from the center to the circumference.The value of random aggregation dimension is the criterion of the optimized trend of tourist scenic spots systems＇ spatial structure.
