摘要： 以成都市茶馆游憩场点系统为研究对象,在全市尺度和著名旅游地标、著名茶馆为中心的0.5 km、1.0 km等多级尺度下,对各茶馆子系统随机聚集维数进行测算。研究发现成都市茶馆系统具有空间随机聚集分形结构特征,而且存在明显的尺度效应。全市尺度下,以天府广场(城市空间分布中心和市行政中心)为中心,成都茶馆呈离心状态分布,空间结构随机聚集性较弱。在0.5 km尺度下,以杜甫草堂等5 个著名旅游地标为系统中心,茶馆子系统未能表现出明显的分形结构特征;以10 个著名茶馆为系统中心,茶馆子系统空间分布呈向心状态分布,空间结构随机聚集性较强。在1.0 km尺度下,以著名旅游地标为系统中心,茶馆子系统多呈现双分形结构,随着尺度范围增大茶馆子系统分形结构特征发育趋于明显;以著名茶馆为系统中心的茶馆子系统,空间结构随机聚集性很强,因此著名茶馆是1.0 km尺度下的茶馆系统自我演化的聚集中心。案例证明分形理论可以在多种空间尺度下指示城市游憩场点系统的微观结构。

Abstract: This paper selects the teahouse system in Chengdu as the object of this research. The city-scale, tourism landmark and famous teahouses are regarded as the center point, the calculation is done on the teahouse’s dimension of the random aggregation in different spacial scales. In the city-scale, teahouses present a centrifugal distribution, with the Tianfu square (which is the center of the spatial distribution in the city and the administrative center) being the center point and the random aggregation of the spatical structure is relatively weak. Within the 0.5 km away from attractions, with the tourism landmark as the center point, the teahouse subsystem’s fractal structure characteristics are not obvious; With ten famous tea-houses being the center point, the spatial structure of the tea-house subsystem appears to be the centripetal distribution and its random aggregation is relatively strong. Within the 1.0 km away from the attractions, the spatial structure of each teahouse subsystem appears to be the double fractal structure when the five famous teahouses are regarded as the center point, and the teahouse subsystem’s fractal structure characteristics become increasingly obvious with the enlargement of the scale. With the ten famous teahouses as the center point, the random aggregation of the spatial structure of the tea-house subsystem is relatively strong,which demonstrates that the scale of 1.0 km is the aggregation center when the famous teahouse subsystem conducts self-evolution,and the spatial structure appears to be evident fractal structure. The case demonstrates that the fractal theory could be applied to indicate the microscopic spatial structure of the recreation space in city in different scales.
