基于多源数据的南京市主城区城市功能分区识别研究
Research on urban functional zoning identification in Nanjing main urban area based on multi-source data
摘要
Abstract
For urban planning,the identification of urban functional areas is the first move for specific urban planning and construction,and the high-precision identification results can provide data support for the optimiza-tion and upgrading of urban spatial structure and the rational allocation of resources.This paper focuses on the main urban area of Nanjing,uses the buffer zone and frequency density algorithm,combines POI data and OSM road network data to identify the urban functional areas,and uses the OSM road network data(irregular grid)and fishing net analysis tool(regular grid)to segment the main urban area to obtain the research unit.The for-mer is used for buffer analysis,and the latter is used for frequency density,the identification results are ob-tained,and the comparison analysis is carried out.The results show that the irregular grid based on OSM road network data has higher recognition accuracy in large-scale research units,and can better reflect the continuity and coordination of the functional area.The regular grid based on fishing net analysis has higher accuracy at me-dium and small scales,and can better reflect the details and spatial changes of the functional area.In general,the identification results of the two methods are consistent with the actual functional area scope and type of the main urban area of Nanjing,which provides reference significance for the planning and development of Nanjing.关键词
