摘要

城市各类公共服务设施布局对于居民服务设施的可获得性具有重要意义,可达性是评价设施布局与获得的有效手段。文章基于兴趣点数据将北京城六区的公共服务设施划分为7类,采用累计机会法对各类公共服务设施进行可达性评价,并在此基础上引入熵值法测度设施的综合可达性。结果表明,各类设施的空间分布并没有向城区中心地区集中,没有明显的中心集聚地,而各类设施可达性有相似的空间模式,均向城区中心集聚,并由中心向外围递减,单中心结构特征明显。各街道获得的各类设施数量存在显著差异,购物、餐饮、休闲娱乐设施的可获得数量高于其他设施,游憩设施平均可获得数量最少。各街道综合设施的可达性与基于熵值法的可达性具有相似的空间格局,多样性会降低或提高街道可达性位序,但对可达性空间分布变化的影响并不明显。

Abstract

The distribution of public facilities has an important influence on people's access to public services, and accessibility is an effective tool to assess the distribution of facilities and access to facilities. There are few previous studies focus on accessibility of facilities with diversity, most mainly focus on evaluating single facility. This article classifies the POI data of six districts into 7 major types of facility in Beijing, uses the cumulative-opportunity approach to measure the accessibility of facilities at jiedao level, and then incorporates entropy into previous indicator to measure accessibility of facility. The results show that the facilities don't gather at the center area, on comparison, the accessibilities of different facilities have a similar spatial pattern with single center structure character, the higher accessibility scores tend to the central areas but lower accessibility scores tend to peripheral areas. The jiedaos have different numbers of facilities to access, such as shopping, catering or leisure and recreation are higher than other facilities' accessibilities, the accessibility level of recreational facilities is the smallest among facilities. Accessing to the number and diversity of facilities for jiedaos have also the similar spatial pattern, the diversity can improve the ranking of poor accessibility areas, but has less effect on change of spatial distribution of accessibility. According to case study, this article discusses some meanings on existing study and practice.

Key words： public service facilities; accessibility; diversity; living service facilities; jiedaos; spatial pattern; Beijing
