【摘要】 在分析武汉市1998、2002、2008年3期遥感影像的基础上,提取出了全市轨道交通建设前后沿线土地利用变化信息,借助9个景观指数,定量研究了轨道交通沿线范围内的土地利用格局的变化趋势。结果表明,轨道交通的建设对沿线土地利用带来了较大变化,表现在:建筑用地占主导,正在迅速聚集成片状;以草地为代表的地类等小斑块的个数呈减少趋势,分布不均衡。更多还原

【Abstract】 The information of urban land use was interpreted before and after construction of Wuhan rail transit from remote sensing imagery in 1998,2002 and 2008.Subsequently,nine landscape Indexes were calculated and used to describe the pattern of land use change.The results showed that the construction of rail transit leads to a serious land use change.The built-up area was a dominant land use type and patches and has an obvious concentrated aggregation distribution for the overall spatial pattern;while some small patches such grass land,which were decreasing,represent imbalance pattern at a certain degree.更多还原
