城市游憩场点系统是和谐城市规划建设的核心对象,也是一种结构复杂的自然-人文复合系统.本文选取随机聚集维数、空间关联维数、网格维数三项指标.以苏州市区为例,对新时期我国城市游憩场点系统的空间结构分形及优化进行了系统论证与解析.研究发现:①城市游憩场点系统的空间结构是具有分形特性的;②各分维指标能够准确地刻画城市游憩场点系统的空间结构及其分异,也为环城游憩带理论及城乡二元游憩结构分异现象等提供了分形解释依据;③苏州游憩场点系统的空间结构呈现出一种核心松散-外围紧致、白组织能力离心化现象比较严重的结构递变趋势,这种结构模式与游憩需求的空间分布结构基本吻合,它准确反映了成熟型游憩场点系统的空间发展态势,也说明加强对游憩场点系统的自组织能力的引导和提升,是和谐城市规划建设中的一项不可或缺的重要工作;④与以往研究结论相对比,发现游憩场点系统与旅游景区(点)系统在空间结构上存在合理的分形差异. |

City recreation sites system is one kind of complex system combining nature with so-cio-culture, and it is also the core object of harmonious city development planning. The spatial structure of Suzhou recreation sites system is studied during the new period of China using fractal theories and methods. Suzhou recreation sites system is divided into three recreation subsystems located in the ancient city, new city and outer city areas, which are the three districts planned in the 2008 general planning of Suzhou city. Then, using the aggregation dimension, spatial correlation dimension and grid dimension as indexes, the spatial structures of Suzhou recreation sites system are studied thoroughly. Results and findings are as follows. Firstly, city recreation sites system is fractal, and it has good fractal characteristics. Secondly, the fractal indexes depict recreation system structure well. They are helpful to interpret the theory of ReBAM and can be used for recreation system optimization. Thirdly, the spatial structure of Suzhou recreation sites system exhibit a gradient tendency from a loose core to a compact extended structure, and the decentralization phenomenon of self-organization ability stands out. The distribution pattern of recreation sites system has a similar structure as the demand structure for recreation sites and it can depict the spatial development tendency of mature recreation sites system well. Accordingly, it is a kind of absolutely necessary work that guides and improves the self-organization ability of recreation sites system in our harmonious city development. Lastly, contrasting with the former research results, it shows that recreation sites system and tourism attractions system have different fractal structures, but it is reasonable and caters to the essence of recreation and tourism. |
