基于POI数据的体育中心周边环境演变研究--以哈尔滨国际会展体育中心为例

Study on the Evolution of Surrounding Environment of Sports Center Based on POI Data:A Case Study of Harbin International Exhibition and Sports Center

体育中心的选址规划对城市发展影响深远,尤其是对其外延周边区域具有显著影响和推动。基于哈尔滨4区3年POI数据和ArcGIS空间分析探讨体育中心周边环境的演变特征与成因机制,结果表明:(1)周边整体呈现单侧集聚演变特征;(2)半径3km范围的各类POI呈现带状集聚、单核集聚、散布或平摊型分布及变化规律,且存在明显功能分区;(3)周边用地功能由特定类型集聚趋向多元混合,主体育场半径1km范围内以生活属性为主,是体育中心辐射效应最强的核心区。

The site planning of the sports center has a profound influence on the urban development,especially on the surrounding areas of its extension.Based on three years'POI data and ArcGIS spatial analysis of the four districts in Harbin,the evolution characteristics and cause mechanism of the surrounding environment of the sports center are discussed.The results show that:(l)the surrounding environment shows the characteristics of unilateral agglomeration evolution.(2)All kinds of POI with a radius of 3km showed a pattern of banded agglomeration,mono-core agglomeration,dispersion or amortization,and showed obvious functional zoning.(3)The peripheral land use functions tend to be diversified and mixed from specific types.The radius of the main stadium is lkm,which is the core area withthe strongestradiation effect of thesports center.
