摘 要: 以成都市为例,在对城市公共游憩空间(urban public recreational spaces,UPRS)进行分类的基础上,采用区位熵揭示各游憩空间类在某一区域的规模优势,并采用核密度等方法分析游憩资源的空间分布模式。依据游憩资源的性质、功能和主要服务方向将UPRS分为4主类16干类107支类。根据UPRS数量和区位熵变化,将成都市划分为中央游憩区与环城游憩带(recreational belt around metropolis,ReBAM),并基于标志性UPRS(symbolic UPRS,SUPRS)的概念,构建了以成都市为中心的游憩机会环。研究发现,UPRS在数量上遵循“距离衰减法则”,在空间分布上呈圈层结构,且每一环带都有其SUPRS. 成都市UPRS扩散在宏观上遵循等级扩散规律,在中观或微观上又遵循轴向扩散和接触扩散规律。
关 键 词: 地理学;城市公共游憩空间;区位熵;成都市;标志性城市公共游憩空间;游憩机会环

Abstract: Taking Chengdu city as an example, on the basis of classification of urban public recreational spaces (UPRS), location entropy index is used to reveal the scale advantages of each type of recreational spaces in a certain area, and nuclear density and other methods are used to analyze the spatial distribution pattern of recreational resources. Four systems, sixteen families, and one hundred and seven branches of UPRS are categorized based on the characteristics of recreation resources, functions and the main direction of the service. Central recreational area and recreational belt around metropolis (ReBAM) are formed in Chengdu city, according to the spatial variation of the numbers and location entropy index of UPRS. The concept of symbolic UPRS (SUPRS) is put forward, and a recreation opportunity ring centered on Chengdu is constructed. It is found that UPRS follows the “the law of distance attenuation” in quantity and has a circle layer structure in spatial distribution, and each belt has its own SUPRS which changes with the distance from the city center. From the diffusion model of UPRS, for Metropolis of Chengdu, its diffusion follows the law of hierarchy diffusion in the macro level, axial diffusion and contagious diffusion at the meso or micro level.
Key words: geography; urban public recreational spaces (UPRS); location entropy index; Chengdu city; symbolic urban public recreational spaces (SUPRS); recreation opportunity ring
