摘要
准确掌握城市空间发展情况及过程，判别城市空间发展的趋势，为城市整体发展制订合理规划有重要的现实意义。本文选取1995～2015年间4个时段的影像数据，提取不同时间段的城市空间范围，利用GIS空间分析技术对哈尔滨市城市空间扩展情况进行监测。分析结果显示，哈尔滨城市空间较为离散，主城区面积逐年增加，年均增长保持在10％以上，2005年后增速明显加快，2015年城区范围趋于稳定。
Accurately grasp the urban space development and process of judging the trend of the development of the urban space, reasonable planning for the overall urban development has important practical significance. This article selects four times between 1995 and 2015 of the image data, extract the different periods of urban space, using the GIS spatial analysis technology of Harbin city spatial expansion to monitor the situation. Analysis results show that the Harbin city space is discrete, the main area is increasing year by year, average annual growth remains above 10% , speeding up growth after 2005, 2015, and city scale tends to be stable.
