摘要/Abstract

摘要： 识别城市多中心空间结构，描述不同职能中心的空间集聚特征，刻画沈阳市中心城区制造业郊区化扩散趋势，为沈阳市中心城区产业结构转型升级和城市空间组织营造提供参考。基于不同职能的兴趣点(point of interest, POI)数据的城市职能分类基准，采用ArcGIS10.7、GeoDa1.12和Crimestat3.3软件，运用核密度分析、空间热点聚类、标准差椭圆、空间自相关等方法，识别2020年城市多中心空间结构，测度不同功能类型设施的空间关联性，分析1998年、2008年和2020年制造业集聚特征。研究表明：1）2020年，城市空间结构表现为“多个中心、圈层放射”，通过“一主四副”的城市规划引导，大致形成了3个等级的城市中心体系，基本符合2011—2020年沈阳市城市总体规划。除了主城区的集聚组团式的单中心之外，各个副城也都形成了各自的次级中心，符合多中心的城市空间结构。2）1998—2020年，制造业企业不断向城市外围地区迁移扩散，主要分布在西、南方向的三四环城市郊区，形成了铁西产业新城、永安新城等产业集聚区域，基本符合2011—2020年沈阳市城市总体规划。3）沈阳市不同功能空间均呈现出西南—东北方向的延伸，不同功能类型之间存在明显的“中心—外围”的嵌套式城市功能体系。不同功能类型呈现出不同的空间相关性，以制造业为代表的工业功能区具有一定的排他性，制造业集聚区域的城市功能比较单一，居住设施、商业服务设施、公共管理与服务功能设施存在较强的空间相关性，形成多种功能混合的综合服务中心。因此，需要进一步提升城市功能和优化产业布局，完善以城市核心生产功能为主的工业区的生活服务功能。

Abstract:

This paper, based on recognition of urban multiple-centralization spatial structure, analyzes their spatial conglomeration of different functionalities, and studies the expanding trend of suburbanization of downtown’s manufacturing in Shenyang, and presents references for upgrading Shenyang’s downtown manufacturing and urban spatial organization. This paper uses POI data, ArcGIS10.7, GeoDa1.12 and Crimestat 3.3 softwares to identify 2020 urban multiplecentralized spatial structure by means of core density, spatial hotspot conglomeration, standard variance eclipse and spatial auto-correlation, and measures their spatial correlation among different functional facilities, and analyzes the manufacturing conglomeration in 1998, 2008 and 2020. In 2020, Shenyang’s urban spatial structure is characterized by “multiple-centralized, layer-radiated”, forming three-hierarchy urban centralized systems through a urban planning “one-major-four-minor”, generally consistent with Shenyang’s 2011 to 2020 overall urban planning. Besides single center in downtown, each minor city also has itself minor center, corresponding to multiple-centralized urban spatial structure. During 1998 to 2020, manufacturing has been migrating outward from downtown, mainly distributing in the third and forth rings in west and south, like Tiexi new city and Yongan new city. Shenyang’s functional space displays southwest to northeast extension with “center-suburb” urban function system. Spatial correlation exists among different functional districts. Industrial district represented by manufacturing is exclusive with single urban function, having strong spatial correlation among residential, commercial, public administrative and functional facilities as a comprehensive servicing center. This paper presents suggestions for Shenyang on further improving urban functions and optimizing industrial layout, and boosting living services in the industrial district which is of urban core production functions.

Key words: urban spatial structure, industrial spatial pattern, multiple-centralization;POI(point of interest), Shenyang city
