【摘要】 随着我国城市规划的重心从增量规划转为存量规划,收缩城市的研究显得愈加重要,街道作为城市的基本要素之一,其空间品质的变化应是衡量收缩城市变化的重要参考。本文以腾讯街景图片为载体,评判了齐齐哈尔中心城区在2013~2015年的街道空间品质变化。研究发现,齐齐哈尔的街道空间品质总体呈变好趋势,但其迅速变化的底商却显示出经济式微的迹象,基于此,文章提出中国收缩城市的"人口—经济—空间下行滞后"现象,来描述收缩城市在收缩过程中的人口、经济和空间品质的变化模式。更多还原

【Abstract】 As the focus of urban planning in China converts from incremental planning to stock-based planning, researches concerning shrinking cities become increasingly important. Street being one of the basic elements of cities, the changes of spatial quality of it are essential to the evaluation of the changes of shrinking cities. This study uses street views from the Tencent Maps to evaluate the changes of quality of street space in the central districts of Qiqihar from 2013 to 2015. The research reveals that the quality of street space of Qiqihar is getting better while the rapid change of commercial real estate under residential buildings suggests a decline in economy. Based on this finding, the "Population-Economy-Space Decline Lagging Phenomenon" is proposed to illustrate the change mode of population, economy and spatial quality during the shrinking process of cities.更多还原
