基于POI数据贵阳市的生活服务业空间格局研究

Research on the Spatial Pattern of Life Service Industry in Guiyang Based on POI Data

摘要: 基于贵阳市七类生活类服务业POI数据，运用核密度分析、标准差椭圆分析，相关性分析对贵阳市生活服务业空间格局进行研究。结果发现：1) 餐饮、住宿、医疗、购物、教育培训、日常服务、体育休闲这七类生活服务业在主城区南明区和云岩区交界处出现连片密集区域，非主城区域外县市出现单个密集区域。并且七类服务业密集区域在空间出现重叠性。2) 各类生活服务业具有较强的相关性，空间相关系数比较之下，餐饮和日常服务业与其他服务业空间相关程度较大，而住宿类服务业最低。3) 标准差椭圆分析结果来看，贵阳市这七类生活服务业中心空间位置接近，且空间分布方向呈东北–西南走向。餐饮类和住宿类服务业的空间分布较密，购物设施类空间分布较广。

Abstract: Based on the POI data of seven types of life service industry in Guiyang, the spatial pattern of life service industry in Guiyang is studied by using kernel density analysis, standard deviation ellipse analysis and correlation analysis. The results showed that: 1) Seven types of life service industries, including catering, accommodation, medical care, shopping, education and training, daily services, and sports and leisure, appeared in contiguous dense areas at the junction of Nanming District and Yunyan District in the main urban area, and counties and cities outside the main urban area. A sin-gle dense area appears. And the seven types of service-intensive areas overlap in space. 2) Various types of life service industries have strong correlations. Compared with the spatial correlation coef-ficient, the catering and daily service industries have a greater degree of spatial correlation with other service industries, while the accommodation service industry is the lowest. 3) According to the standard deviation ellipse analysis results, the seven types of life service industry centers in Guiyang are close to each other in space, and the spatial distribution direction is north-east-southwest. The spatial distribution of catering and accommodation services is relatively dense, and the spatial distribution of shopping facilities is relatively wide.
