Urban land cover is mainly composed of complicated artifi- cial materials, which is the key factor to limit the de- velopment of the spectral mixture analysis technique. There are two main aspects in which the technique of spectral mixture analysis is applied to urban geog- raphy: one is to calculate vegetation fraction; the other is to build quantitative model of the urban im- pervious surface obtained from the combination be- tween high albedo fraction and low albedo fraction. The technique of spectral mixture analysis is firstly applied to study urban renewal pattern, scale and mode which happened in Shanghai City from 1997 to 2000. 关 键 词：遥感 分布类型 城市更新 上海 线性光谱分析
