摘要
利用3S技术对Landsat 5和Landsat 8影像进行处理。采用监督分类方法提取2010和2014年黄州区2期土地利用信息,生成土地利用类型转移矩阵,应用土地利用动态度分析土地利用类型的时空变化规律。结果表明,2010—2014年黄州区建筑用地处于增长的趋势,其他的土地类型都在减少,黄冈市各土地利用类型面积总变化由大到小依次为建筑用地、耕地、水域、林地、其他用地,建筑用地和耕地变化速度快,其他3种类型的变化速度相对较慢。
By processesing Landsat 5 and Landsat 8 images of Huangzhou District with 3S technology,the land use information of Huangzhou District in 2010 and 2014 was extracted by supervised classification. Spatio-temporal variation rules were explored by counting area and building change matrix. The results showed that area of building land in Huangzhou District increased in the last 5 years and other land decreased in the 5 years. In addition,the absolute change area of land use types ranked from large to small as building land,cultivated land,water area, forest land, other land, change speed of building land and cultivated land was higher than the others.
