Abstract：It is helpful for promoting recreational belt construction to research the diffusion law of recreational space.The location entropy index of recreation activities is adopted to identity the symbolic recreational activities and recreation opportunity ring, and to analysis the diffusion law of recreational activities, based on the classification to recreational activities spaces. Four systems, sixteen families, and one hundred and seven branches of public urban recreational spaces 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 are formed according the spatial variation of the numbers and location entropy index of recreation facilities. Recreation facilities present pyramid structure in number, and ring structure in space. Distribution of recreation facilities in space follow the "the law of distance attenuation".The density of recreation facilities is biggest and the type is various in central zone of urban. And the recreation facilities to the type of shopping, catering is for the most. In the suburban areas, recreation facilities density decreases and the type of recreation and fitness have its relative advantage. The recreation facilities showing a characteristic of specialization in topic in outer suburb district and natural recreation space like natural scenic area and culture comprehensive recreational facilities has the relative advantage, the recreation facility density is much lower than the central area and suburb. Symbolic recreational activities will changes with the distance from the city center.From the diffusion model of recreation activities, for Metropolis of Chengdu, the recreation facilities diffusion in space, followed by the law of hierarchy diffusion in the macro level, axial diffusion and contagious diffusion at the meso or micro level.
