基于土地利用转移矩阵的吉林省中部城市群LUCC分析
|
摘要
基于RS和GIS方法,对吉林省中部城市群1990—2017年间4个时期的遥感影像进行分析处理,应用土地利用转移矩阵对城市群范围内LUCC进行计算和对比.研究结果表明:随着城市化进程加快,研究区耕地、林地和未利用土地逐年减少,城乡居民用地逐年增加,草地和水域面积变化不明显,在城市化建设进程中需要注重合理利用土地资源,保护生态环境,形成稳定发展的城市群生态空间系统.
The remote sensing images of 4 periods during 1990 to 2017 in the middle urban agglomeration of Jilin province were analyzed,based on the RS and GIS methods. Then the land use transfer matrix was used to calculate and compare the LUCC in the urban agglomeration. The results show that,with the accelerated process of urbanization,the cultivated land,woodland and unused land in the study area were decreasing year by year,the urban and rural residential land was increasing year by year,the change of grassland and water area was not obvious. In the process of urbanization construction,it is necessary to pay attention to the rational use of land resources,protect the environment and form a stable development city group ecological space system.
