摘 要: 根据福州市1988年TM影像和2001年A STER影像,运用多波段K-L变换法提取城市用地及其变化信息.结果表明:多波段K-L变换法集中了两个时相的影像信息,信息量丰富,变化信息突出,根据变换结果福州市城市用地可分成“高密度旧城市用地”、“中低密度旧城市用地”和“新城市用地”,“新城市用地”包括旧城区内的新建筑物和新兴工业园区,前者建筑密度较高,后者密度较低. A TM image and an ASTER image of Fuzhou City were used to extract the urban landuse and its change information of the research area by the multi-band K-L transform. The result showed that the method join the information of two images, making the change information obvious. Based on the transform result the urban land-use can be classified into "high density old urban landuse", "moderate and low density old urban land-use" and "new urban land-use" and "new urban landuse" includes the new buildings in the old city and the new industrial areas, the former belongs to the high density urban land-use, while the latter's density is moderate and low.
