摘要
利用武汉市不同时相的遥感影像进行城市土地利用解译和处理,提取城市新、旧建成区区块用地,通过GIS软件提供的空间统计分析功能对城市用地空间分布进行定量分析与描述,具体分析了研究区土地利用外部扩展动态变化特征,从而揭示了城市用地扩展的时空规律。
Based on the data of the urban landuse at different stages in Wuhan city by remote sensing interpretation and procession,its new and old urban district was drawn.Assisted by spatial analysis and statistic techniques of GIS,the spatial distribution of urban landuse was analyzed.The characteristics of dynamic change of urban landuse were studied.And time-space law of urban expansion was pointed out.
