基于核密度分析的无障碍设施分析

Analysis of Barrier-free Facilities Based on Kernel Density Function

为提升首都城市的基础设施环境质量,本文基于核心区无障碍设施数据成果,应用核密度分析方法,开展对首都功能核心区的盲道、出入口、地铁电梯、公共厕所、停车场、坡道进行现状分析,并对其无障碍设施普及程度展开研究。通过核密度分析,盲道呈现“三心汇聚、离心递减”的特征,出入口呈现“两翼齐飞”的特征。通过现状研究,无障碍设施存在的问题总体上表现为设施数量不足,质量不高,分布不均衡等特点,为政府和规划管理部门提供相应的决策依据。

In order to improve the environmental quality of infrastructure in the capital city,based on the data results of barrier free facilities in the core area,this paper uses Kernel density function method to analyze the current situation of blind path,entrance and exit,subway elevator,public toilet,parking lot and ramp in the core functional area of the capital,and to analyse the accessibility rate.From the analysis,the blind path presents the layout characteristics of“three centers converging and centrifugal decreasing”,and the distribution of entrances and exits shows the spatial pattern of“two wings flying together”,and the spatial distribution of elevators is characterized by“circular agglomeration and low-lying in the middle”.Through the research of the current situation,the existing problems of barrier free facilities are generally characterized by insufficient number,low quality and unbalanced distribution of facilities,which provide the government and planning management departments with the corresponding decision-making basis.
