基于遥感技术的土地利用/土地覆盖信息提取——以四川省眉山市青神县为例

Information Extraction for Land Use/Land Cover Based on RS Techniques——A Case of Qingshen County in Sichuan

以四川省眉山市青神县作为研究区,利用TM1、2、3波段组合的遥感影像数据,采用Erdas、ArcGIS、ArcView等遥感及地理信息系统软件,对2007年的土地利用/土地覆盖现状进行分析,通过图像预处理及目视解译,获取了研究区的土地利用类型及其分布特征。

Taking the Qingshen county of Meishan city in Sichuan Province for study area, using TM1, 2, 3-band combination of remote sensing image data in Erdas, ArcGIS, ArcView and othe Geographic Information System platform, we analyze the situation of the land use / land cover in 2007, and then, through the image pre-processing and visual interpretation, we obtain six major land-use types （forest land, grassland, urban and rural settlements, industrial and mining land and unused land） and their distribution characteristics.
