摘　　要：基于海口城市化建设发展使得高密度居住空间与城市公园绿地存在一定程度不匹配的情况下,居民无法公平享有公园绿地服务。研究以海口市建成区的公园绿地为对象,运用核密度分析和网络分析方法,探究其空间分布特征和可达性。研究旨在了解城市公园绿地的布局模式,以及步行和骑行两种出行方式下公园绿地服务范围和居住区到公园绿地的可达性的对比分析。研究显示:海口市建成区公园绿地可达性与城市绿地、道路、住区密度值有较强关系。公园可达性在15min之内步行、骑行方式下整体呈现不均衡局面;各街道骑行可达性较好,但在步行服务水平之间可达性差异较大,大多数街道存在服务盲区,直观反映了居民绿地服务需求没有被实现。研究结果为改善城市绿地布局提供数据支撑和理论依据。Based on the development of urbanization in Haikou,there is a certain degree of mismatch between high-density residential space and urban parks,and the residents cannot enjoy the parks and green space services equitably.Taking the park green space in the built-up area of Haikou city as the object,we explore its spatial distribution characteristics and accessibility by using kernel density analysis and network analysis methods.The study aims to understand the layout pattern of urban parks and greenspaces,as well as the comparative analysis of the service scope of parks and the accessibility of residential areas to parks and greenspaces under the two modes of transportation:walking and cycling.The study shows that park green space accessibility in the built-up area of Haikou City has a strong relationship with the density values of urban green space,roads and settlements.Park accessibility within 15min walking,cycling mode as a whole presents an unbalanced situation;the streets cycling accessibility is better,but in the walking level of service between the accessibility has large differences,there are service blind zones in most of the streets,intuitively reflecting the residents of green space service needs have not been realized.The results of the study provide data support and theoretical basis for improving the layout of urban green space.
