【摘要】 使用了自主研发的自组织神经网络分类(SOFM)方法[1～3],选择了1988、1994、2001和2003年5～6月份TM+时间序列多光谱遥感数据,对北京城市增长方式进行了30m分辨率遥感时序数据的鉴别,包括填充式增长方式、扩张式增长方式、独立式增长方式、线状式增长方式和簇状增长方式,并绘制了三个时期的城市增长图。在此基础上,根据北京城市增长环线驱动的特点,分别对四环内、四环至五环、五环至六环1988～1994年、1994～2001年、2001～2003年的5种城市扩展方式面积进行了统计。更多还原

【Abstract】 This paper applies the SOFM (self organized feature map of neural network) classification software, and choose the Landsat temporal TM images in Mays or Junes of 1988, 1994, 2001 and 2003 and applies the five forms of urban expansion identification model considering the ring roads. The results shows that infillment and expansion are the main forms in the three periods of urban growth process from 1988 to 2001, from 1994 to 2001 and from 2001 to 2003, while the linear branch and clustered branch are the main forms in the urban growth from 1994 to 2001 between the fifth and sixth ring roads.更多还原
