摘要
成都市是“公园城市”首提地和示范区,科学评估其综合性公园可达性,对成都优化公园空间布局,建设美丽宜居公园城市具有重要意义。本文以成都市中心城区23个综合性公园作为研究对象,利用空间句法和ArcGIS软件建立线段模型,并利用POI(point of interest)数据对比分析与模型校验,从全局可达性、局部可达性和感知可达性3个方面对成都市中心城区综合性公园的空间分布特征和可达性进行研究。结果表明:成都市中心城区综合性公园分布不均衡,POI高值区域综合性公园分布偏少,与城市居民需求匹配性偏弱;城市道路交通网络有待完善,区域发展不够协调;公园全局、局部可达性总体水平较高,大部分公园分布于可达性高值区域,部分公园自身缺乏一定的吸引力,感知可达性一般。影响公园可达性的因素包括空间路网结构、公园空间分布、自然和人文环境等多方面,在此基础上提出合理布局和增设综合性公园;优化城市道路交通网络;增设公交站台、地铁站点;融合成都独特的山水文化和历史文化以提升景观吸引力等建议。
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.
