摘要
以苏锡常地区为研究区域,选择19861、995年的Landsat TM以及2006年的ETM+遥感图像为主要数据源,根据国家分类标准以及地区特征,利用人工解译和监督分类结合的方法提取苏锡常地区土地利用类型信息,采用GIS空间分析方法和数理统计方法对研究区土地利用动态变化进行定量分析。结果表明,研究期内苏锡常地区土地利用类型变化主要表现为耕地的大幅减少和城镇村及工矿用地的明显增加,综合土地变化速度为0.68%。
According to the Landsat TM and ETM＋RS images in 1986,1995 and 2006,as well as the national classification standards and regional features,the visual interpretation and supervised classification methods were combined to extract the land use type information in Suzhou,Wuxi and Changzhou,the GIS spatial analysis and mathematical statistical methods were adopted to quantitatively analyze the dynamic change of regional land use.Results showed that the great changes of the land use types in those three places during the study period were mainly characterized by the substantial decrease of farmland area and the obvious increase of city,town,village area and industrial and mining lands,the overall land change rate was 0.68%.
