摘　　要：利用Landsat 7的ETM影像,以贵州省镇宁县作为研究区域,在RS及GIS软件的支持下,对遥感图像进行几何精纠正、直方图均衡化处理等图像预处理。选用432波段进行标准假色彩合成,并结合数字高程数据、土地利用现状图等背景数据进行图像辨读解译,完成7种地类的景观斑块图,并运用Fragstat景观指标计算程序,对数据进行景观指数上的分析,为当地土地规划及生态保护提供参考。Using ETM image of Landsat 7,focusing on Zhenning County of Guizhou Province,with support of RS and GIS,image preprocessions were carried out,including geometry rectification and histogrem equalization under support of RS and GIS software.432 waveband was selected to synthesize a standard pseudo color.Combined with DEM,land use status figure and other background data,the image discrimination interpretation was made.The landscape plaque maps of 7 kinds of land types were finished.Using Fragstat landscape index calculationprogram,the landscape index of the data was analyzed,so as to provide reference for the local land programming and ecosystem protection.
