【摘要】 近年来,浙江省经济飞速发展,城镇规模迅速扩大,但有关全省城镇建成区扩展面积的具体数量和扩展速度的客观数据还很缺乏。利用多时相的Landsat卫星遥感图像数据,采用目视解译与计算机自动分类方法,对1998～2001年浙江省城镇时空扩展进行了调查。调查结果显示,1998年和2001年浙江省县级以上城市建成区面积分别为977 85km2和1499 06km2,3年内全省县级以上城市建成区面积扩展了521 21km2,年增长速率达15 31%。在此基础上,根据区域社会经济统计数据,对城镇经济发展与城市空间扩展的相关性进行了分析。更多还原

【Abstract】 Urban expansion was very rapid with the economic development in Zhejiang Province in recent years. It was important to obtain timely the area and speed data of urban expansion for drafting the sustainable development stratagem of society.However,it was difficult to investigate timely the area and speed of urban expansion for many traditional methods.In the paper,the satellite images at different times were applied to investigate the urban expansion process of cities in Zhejiang Province from 1998 to 2001.The areas of cities of Zhejiang in 1998 and 2001 were 977.85km2 and 1499.06km2 respectively,and there was a mean anual increase of 15.31%.On the basis of the urban expansion data using remote sensing, combined with socio-economic data,driving forces to urban expansion were analyzed.更多还原
