基于Landsat影像的泰州市土地利用变化分析

Analysis of Land Use Changes in Taizhou City Based on Landsat Images

利用Landsat系列卫星数据,提取泰州市1995年至2005年间的土地利用现状信息,利用GIS技术进行空间分析,生成研究区土地利用转移矩阵,在此基础上,研究分析10多年来泰州市土地利用变化的情况。研究结果表明,10多年来泰州市耕地得到了很好的保护,水域面积虽然略有下降,但基本保持稳定,城市的发展呈现出新特点,城市的核心作用在泰州市的城市化过程中充分体现了出来。

Landsat remote sensing images were used to obtain the land use information of Taizhou City from 1995 to 2005. Land-use transfer matrix in the area was generated by spatial analysis u- sing GIS technology. Results showed that during the ten years, the arable land in Taizhou City was protected well. The water area remained stable with a slight decline in the quantity of water areas. There were new characteristics in local city development, and the core effect of city was highlighted during the process of urbanization.
