【摘要】：城市公园绿地为购物娱乐设施消费能力较低的低收入者提供休息、交往、游乐的免费活动场所,满足了人们的精神文化需求。以武汉市公园绿地为研究对象,运用两步移动搜索法(2SFCA)计算研究区内低收入者基于步行、自行车、公交三种交通方式下的公园绿地可达性。采用皮尔森相关系数、洛伦兹曲线和区位熵的方法,分析公园绿地分布和低收入人口的相关性和空间匹配程度及格局。研究结果表明:(1)三种交通方式下研究区内街道的公园可达性差异较大,呈现出低收入群体内部两极分化的特征;(2)公园绿地可达性与低收入人口分布呈现较弱的负相关关系,在公园绿地规划布局选址时没有把低收入人口的出行便捷程度考虑在内;(3)基于公交交通方式下研究区内公园绿地分布和低收入人口分布呈现出空间匹配的格局,而中心城区低收入人口集聚的街道基于步行方式公园可达性较差,需要在这些区域增加规划公园绿地及其之间的绿色廊道来实现区域公平。
[Abstract]:Urban park green space for the low income people with low consumption capacity of shopping and entertainment facilities to provide rest, contact, play free activities to meet the spiritual and cultural needs of people. Wuhan Park Green Space as the research object. Two-step mobile search method was used to calculate the park greenbelt accessibility of low-income people in the study area based on walking bicycle and public transport. Pearson correlation coefficient was used. Lorentz curve and location entropy method. The relationship between park green space distribution and low-income population and the spatial matching degree and pattern were analyzed. The results showed that there was a great difference in the park accessibility of the streets in the study area under the three traffic modes. Showing the characteristics of internal polarization of low-income groups; (2) there is a weak negative correlation between the accessibility of green space and the distribution of low-income population, and the convenience of low-income population is not taken into account in the planning and location of park greenbelt; The distribution of park green space and low-income population in the study area showed a pattern of spatial matching, while the street with low income population concentration in the central urban area was less accessible to the park based on walking mode. There is a need to increase the planning of green parks and green corridors in these areas to achieve regional equity.

【正文快照】： 0引言城市公园绿地作为城市生态系统的重要组成部分,同时也是满足城市居民休闲需要和举办文化活动的重要场所。对于在城市中消费能力较低的低收入者,前往商场、影院、KTV等购物娱乐场所的机会较少,公园绿地作为城市的起居空间,为低收入者提供了大量免费户外活动的空间和设施,
