Abstract: Chengdu is the first site and demonstration area of “park city” in China. Scientific evaluation of its accessibility to comprehensive parks is of great significance for optimizing the spatial layout of parks and building a beautiful and livable park city in Chengdu. 23 comprehensive parks in the central city of Chengdu are selected as the research subjects.Space syntax and ArcGIS software are used to establish the segment model. By comprehensive analysis of the POI data and model checking, the spatial layout characteristicsand accessibility of the comprehensive parks in the downtown area of Chengdu are studied from the following three aspects, global accessibility, accessibility of local accessibility and awareness accessibility. The results show that the distribution of comprehensive parks in downtown Chengdu is not balanced, and the distribution of comprehensive parks in areas with high POI values is less, and the matching between comprehensive parks and urban residents' needs is weak. The urban road traffic network needs to be improved and the regional development is not coordinated enough. The overall level of global and local accessibility of parks is relatively high. Most of the parks are distributed in areas with high accessibility value, and some of the parks lack certain attraction themselves, and the perceived accessibility is mediocre. The factors that affect the accessibility of the park include the structure of the spatial road network, the spatial distribution of the park, the natural and human environment and so on. Based on the above analysis, some suggestion are put forward, such as making a more reasonable distribution of the parks, increasing the numbers of comprehensive parks, optimizing the urban traffic network; Adding more bus stations and subway stations; Integrating Chengdu's unique landscape culture with the historical culture, etc. to enhance the attractiveness of the landscape.

Key words: space syntax, point of interest(POI), accessibility, comprehensive park, Chengdu, China
