【摘要】：城市可持续发展一直是城市地理学和城市规划关注的热点。以南京市为例,测度了城市空间结构紧凑度和城市土地利用效率,并探讨二者的关系。得出以下结论:(1)南京市2002、2007和2012年的城市空间结构均属于较不紧凑状态,且呈下降趋势;"中心区"紧凑度高,且呈上升趋势,城市内部填充与城市外围蔓延扩张现象并存。(2)2002~2012年南京市城市土地利用效率属于中等水平,且呈下降趋势,南京市各区城市土地利用效率差异明显。(3)城市空间结构紧凑通过距离和交通可达性来影响城市内部要素在空间的分布,最终影响城市土地利用效率。基于此,在城市发展过程中应加强城市内部空间合理组织,尤其是加强对交通设施的投入,促进城市要素在空间上的合理分布与流通,提高城市土地利用效率。
[Abstract]:Urban sustainable development has always been the focus of attention in urban geography and urban planning. Taking Nanjing as an example, the compact degree of urban spatial structure and urban land use efficiency are measured. The following conclusions are drawn: the urban spatial structure of Nanjing in 20022007 and 2012 is not compact and has a downward trend, and the "central area" has a high compactness and an upward trend. The urban land use efficiency of Nanjing from 2002 to 2012 belongs to the medium level, and shows a downward trend, and the phenomenon of urban interior filling and urban periphery spreading and expanding coexists, and the urban land use efficiency in Nanjing from 2002 to 2012 is in a moderate level. The difference of urban land use efficiency in every district of Nanjing is obvious. 3) the compact urban spatial structure influences the distribution of urban interior elements in space through distance and traffic accessibility, and finally affects the urban land use efficiency. In the process of urban development, the rational organization of urban interior space should be strengthened, especially the investment in transportation facilities should be strengthened, the rational distribution and circulation of urban elements in space should be promoted, and the efficiency of urban land use should be improved.
