北京市中心城区公共文化设施空间分布研究

Research on Distribution Characteristics of Public Cultural Facilities in Central Area of Beijing City

采用点密度法得到北京文化设施的密度分布图,从设施数量、类型两个方面对其空间分布进行定量和定性探讨。采用基尼系数、区(带)别特化系数、区(带)间差异系数对其分布均衡状况进行测算,发现文化设施在空间分布上具有中间多而集聚、边缘少而分散、区际差异大、集中程度高、沿环线从内到外递减分布的特征;不同种类的文化设施分布特点不一,文化设施分布与人口分布呈现高度一致性,并向交通干道集聚的特点。

Using the dot density method, density distribution map of public cultural facilities in central area of Beijing City was gotten. From the two sides of number and type of facilities, the spatial distribution of public cultural facilities was quantitatively and qualitatively studied. Based on the three indexes ： Gini coefficien, belt difference coefficient and belt specialization coefficient, distribution imbalances of public cultural facilities in central area of Beijing City was calculated. The result showed that public cultural facilities was gathered in the middle and it was small and dispersed on the edge. There were large inter - regional differences and high degree of concentration on the cultural facilities distribution. The distribution was descend- ing along the ring road from inside to outside. Different types of cultural facilities distribution characteristics was vary. The distribution of cultural facil- ities and population distribution were highly consistent. In addition, it showed the characteristics of significant agglomeration to main roads.
