摘　　要：在城市化进程中,城市的形态是城市扩张中直接表现出来的空间行为和形式,在正确制定城市政策和合理规划城市的需求下,研究城市形态空间的演化过程具有重要的现实意义。本文选取江苏省泰州市为研究对象,在美国军事气象卫星DMSP搭载的OLS传感器拍摄影像的基础上,采用基于NDVI修正的阈值提取法对泰州市的扩展模式与城市重心迁移进行了系统的研究,旨在找出泰州市的城市形态空间演化规律并对其空间形态发展趋势及模式进行展望。In the process of urbanization,the urban form is the spatial behavior and form directly manifested in urban expansion.With the correct formulation of urban policies and rational planning of urban needs,it is of great practical significance to study the evolution of urban morphological space.In this paper,Taizhou in Jiangsu is selected as the research object.Based on the images captured by the OLS sensor carried by the US military meteorological satellite DMSP,a threshold extraction method based on NDVI correction is used to systematically study the expansion mode of Taizhou and the migration of the city’s center.It aims to find out the spatial evolution law of urban form in Taizhou and forecast its spatial form development trend and mode.
