Abstract

In this paper, we monitored the urban morphology of the old city of Shanghai and its former foreign concessions from 1985 to 2014. Based on a time-series of Landsat 5, 7 and 8 images, this study used Iteratively Reweighted Multivariate Alteration Detection (IRMAD) analysis to detect land-use modifications from traditional urban pattern to new constructions. Results show that urban transformation mainly started in 1995 and perpetuate at an average rate of 88 ha per year. It also brings out that about 55% of the old urban pattern was modified in 2014. A detailed interpretation highlights the development of modern high-rise buildings, roads and subway networks, green infrastructures but also the conservation of protected historical buildings.
1985 - 2014年上海老城及其前外资聚落城市转型监测
本文对1985 - 2014年上海旧城及其前租界的城市形态进行了监测。基于Landsat 5、7和8的时间序列图像,本研究采用迭代重加权多元变化检测(IRMAD)分析方法,检测从传统城市格局到新建筑的土地利用变化。结果表明,城市转型主要始于1995年,并以平均每年88公顷的速度持续下去。报告还指出,2014年约55%的旧城市格局进行了改造。详细的解释强调了现代高层建筑、道路和地铁网络、绿色基础设施的发展,以及受保护的历史建筑的保护。
