为了分析高分辨率遥感影像在土地覆被监测中的适用性,以SPOT5和“资源一号”02C卫星高分辨率遥感影像为数据源,对两种数据的波段组合和数据融合方法进行分析评价,并建立相应的土地覆被解译标志,提取研究区2005年和2012年两期土地覆被信息,基于RS和GIS软件平台,从面积变化、土地利用动态度和转移矩阵3方面研究了土地覆被信息的变化规律.研究结果表明,经过有效合成和融合处理的高分辨影像最大限度地保持了影像的纹理和光谱信息,可以正确识别并提取地物变化边界线,研究成果可为高分辨率遥感影像在土地覆被变化监测中的应用提供一定的参考和依据.%In order to analysis the applicability of high-spatial remote sensing image in land cover change monitoring,this paper choose SPOT5 and ZY-1 02C satellite image as data source,and evaluate its methods of band combination and fusion,built the interpretation symbol of land cover,therefore,the land cover information of 2005 and 2012 in study area were extracted.Based on RS and GIS software platform,the change rule of land use information was analyzed by area change,dynamic degree of land use and transfer matrix.The result show that the high-spatial remote sensing image after the process of efficient synthesis and fusion can keep texture and spectral information in a maximum extent,features boundary change can correctly identify and extract,the research can provide reference and basis for application of high-spatial remote sensing image in land cover change monitoring.
