| 摘 要： | 生活性服务业是服务经济的重要组成部分，其合理布局对发展城市经济、满足居民消费需求具有重要作用。基于长沙市六区POI数据，运用核密度分析、熵指数、频数密度分析及空间聚类等方法研究长沙市生活性服务业的空间格局特征，发现长沙市生活性服务业的分布具有以下特点：1）主要受交通及城市规划指向性影响，沿交通主干道集聚分布，整体布局呈“一核四轴多极”且空间分布与人口集中度联系紧密，东西差异明显，东部多而密集、西部少而分散；2）不同类型的生活性服务业分布特征各异，在空间形态上主要表现为“单核心”、“双核心”和“多核心”等；3）其功能多样性布局呈现以五一广场为核心的“中心-外围”结构特征，功能多样且混合程度高的区域位于城市中心，城市边缘区生活性服务业集聚性较弱且多为单一功能或者双功能混合区。 |

| Abstract: | Consumer service industry is an important part of service economy, and its rational distribution plays an important role in developing urban economy and meeting the consumption demand of residents.As an important point data representing urban spatial facilities, poi is a new data source to study the characteristics of urban spatial pattern. Based on poi data, the spatial pattern of consumer service industry in Changsha was studied by using the methods of kernel density analysis, entropy index, frequency density analysis and spatial clustering. It is found that the consumer service industry of Changsha is mainly influenced by traffic and urban planning. The whole distribution is "one core, four axes, multi-polarity", and the spatial distribution is closely related to population concentration, and the difference between east and west is obvious;The distribution characteristics of different types of consumer service industry are different, which are mainly "single core", "double core" and "multi-core" in spatial form. The distribution of functional diversity is characterized by the central periphery structure at the core of the Wuyi Square. The areas with diverse functions and high degree of mixing are located in the central city, and the consumer service industry in the peripheral area is weak and most of them are single-function or dual-function mixed areas. |
