The rapid development of shared bicycles has also brought great challenges to the old urban road space, which has led to the contradiction between shared bicycle parking spaces and urban slow-moving spaces everywhere. Based on Mobike open data, the article analyzes the time and space characteristics of shared bicycle parking in the main urban areas of Nanjing. According to the temporal characteristics, three types of regions are divided and the speci c regions are listed and analyzed. According to the spatial characteristics, two types of parking contradictions are divided, and their causes are analyzed. Finally, based on the above spatial-temporal features, combined with the corresponding spatial types of speci c areas in Nanjing, a concrete transformation method for urban slow-moving space is proposed.
