山地城市不同级别居住区的城市公园可达性比较研究

A Comparative Study on Accessibility of Urban Parks in Different Levels of Residential Areas in Mountain Cities

为探究渝北区城市公园绿地服务的社会公平性,研究基于路径规划数据与引力模型,从时间可达性、机会可得性、质量差异性以及综合可达性4个层面对渝北区不同级别居住区的城市公园绿地可达性进行了研究.结果表明:①研究区内,居住区到城市公园的时间可达性普遍较低;低级别居住区能更快获得城市公园服务,在一定出行时间内可选择访问的公园数量更多.②对于所有居住区,公园的易访率从大到小依次为:游园、社区公园、专类公园、综合公园;对于不同级别居住区,低级别居住区容易访问的是服务能力较弱的公园,高级别居住容易访问的是服务能力较好的公园.③在综合可达性上,普通住宅区呈现居住区级别越高,城市公园的综合可达性越高的趋势,别墅居住区不符合此趋势.

In order to explore the social fairness of the urban park green space service in Yubei District,the study based on the path planning data and the gravity model,the accessibility of urban park green space of different levels of residential areas in Yubei District was conducted from four levels:time accessibility,opportunity availability,quality difference,and comprehensive accessibility.The results show that,①The time accessibility from residential areas to urban parks is generally low;low-level residential areas can get urban park services faster,and there are more parks to choose from within a certain travel time.②For the entire residential area,the park's accessibility ranking is:amusement park>community park>special park>comprehensive park;for different levels of residential area,the most accessible parks for low-level residential area are parks with weak service capacity,and the most accessible parks for high Level residences are parks with better service capabilities.③In terms of comprehensive accessibility,ordinary residential areas show the tendency that the higher the level of residential areas,the higher the comprehensive accessibility of city parks,that is,the higher the level of residential areas,the better accessibility of the green park services.The Villa living area does not fit this trend.
