本文通过对城市规模的概念介绍,以及检测城市规模使用的技术方法,本文主要是利用1988,1996,2001,2007四年的TM时序遥感影像,对重庆主城区的城市规模扩展进行了监测,分析了自1988-2007年该区域用地规模的动态变化过程及时空特征.同时还对重庆城市用地的规模检测的结果进行了评价.评价结果表明,近二十年来,重庆主城区城市规模扩展迅速,并先后经历了“向西扩展”和“向北扩张”的两个阶段.
本文通過對城市規模的概唸介紹,以及檢測城市規模使用的技術方法,本文主要是利用1988,1996,2001,2007四年的TM時序遙感影像,對重慶主城區的城市規模擴展進行瞭鑑測,分析瞭自1988-2007年該區域用地規模的動態變化過程及時空特徵.同時還對重慶城市用地的規模檢測的結果進行瞭評價.評價結果錶明,近二十年來,重慶主城區城市規模擴展迅速,併先後經歷瞭“嚮西擴展”和“嚮北擴張”的兩箇階段.

In this paper, by the introduction of the concept of city scale, and technical method for the detection of city scale, in this paper mainly by using TM temporal remote sensing images of 1988199620012007 to four years, the urban area of Chongqing city scale expansion were monitored, and the dynamic changes of 1988-2007 area with the size and spatial and temporal characteristics are analyzed. At the same time the scale of the result of detection is evaluated. The evaluation results show that, in the past twenty years, urban area of Chongqing city scale expands rapidly, and has experienced two stages of"westward"and"northward".
