摘要
论文基于相关城市的土地利用数据对城市街区单元平面形态的变化规律进行理论模拟和定量分析。研究结果表明,在外向型城市扩张模式或内向型城市更新模式下,城市街区单元的空间尺度都有明显的增大趋向,区域范围内街区单元的数量也相应减少。造成这一趋势的主要原因在于在经济和社会需求驱动下的建设模式,以房地产企业为代表的社会力量成为城市街区成型的主导力量,基于成本—收益等经济利益考虑,企业倾向于扩大开发项目的空间体量,从而造成了城市街区单元尺度的增大;这一变化本身也深刻影响了城市的居民生活和产业活动。
The purpose of this paper is to do the theoretical simulation and quantitative analysis on evolutional process of urban blocks flat form based on some Chinese city＇s data. The result indicates that, the urban blocks plat form showed significant evolution trends under the background of rapid urbanization. Urban block flat form is based on urban spatial form, which principally reflects constructivism enclosure of land use on space. As far as land use is concerned, urban block spatial form is space module group, which is based on the incision of ground traffic system to urban land. Therefore, on the theoretical significance, urban block flat form depends on spatial design of planning makers, while the latter is affected by external environmental factors, such as economic society and urban development, etc. There are principally two types of urban urban space change mode, extroverted urban expansion mode and introverted urban update mode, in either case, the spatial shape of urban blocks tend to increase their spatial scales as well as to reduce the number of blocks. Social force, such as real estate development enterprises, become the leading force of new urban block forming, and leads to build new urban blocks with appearing ＂super real estate projects＂; on the other hand, in the process of urban renewal, city government and real estate enterprise reach a consensus on urban block scale. It is concluded that, in the process of urban expansion or renewal, it should take promoting residents＇ convenience degree, improving living condition and enhancing slow traffic system efficiency into account and also should consider interrelation between blocks, comprehensive influence of new blocks to whole areas and completing the matching construction of corresponding infrastructures.
