结果表明与传统调查方法相比速度快，工作量大大减少，且把数据库与区域信息系统连接或被调用，不仅可以通过数值的变化，研究区域土地利用状况的变化特征，还可以从图形上体现出土地利用类型的空间分布规律，以及空间分布的动态变化情况。 - Investigation using remote sensing ( rs ) technology can breakthrough the limits of traditional methods , make full use of its capability of integration , visualization , rapidity and vast - dimensions analysis , and get better results the paper takes the up - to - date landsat - 7 etm + data , which is the most widely used , and quickbird data , which has the highest resolution nowadays , and according the features of the data and landslides , processes the quickbird data with 1 : 10 000 dem orthophoto correction and the landsat - 7 etm + data as follows : ( 1 ) selecting optimal spectrum band : selects 753 bands as the optimal bands ; ( 2 ) image intensifying : selects the principle components processing method on the basis of comparing several image intensifying methods ; ( 3 ) rigour geometric direction : corrects the geometric distortion of the map ; ( 4 ) image fusion : mainly takes his space transform fusion and resolution fusion method , and acquires maps with higher spectrum resolution as well as space resolution . after that , the visual effect of the image has been enhanced , and the interpretation precision
采用遥感技术，可以突破传统调查方法的限制，发挥其宏观、综合、直观、快速的特点，取得更好的效果。论文选取目前应用最广的陆地卫星最新系列landsat - 7etm +数据和空间分辨率最高的商业卫星quickbird数据作为主要的数据源，根据数据的特点及滑坡灾害应用特征，对quickbird遥感数据则基于1 ： 10000dem进行了正射校正，对etm +遥感数据进行了波段优选，选取了753作为最佳组合波段；图像增强，通过各种增强处理方法的效果对比，选择主成分分析法对图像进行增强；几何精校正，纠正图像的几何变形；影像融合，主要选取了效果较好的his空间变换融合和分辨率融合，得到的图像既具有较高的光谱分辨率，同时也具有较高的空间分辨率。经过上述数字处理，较好地改善了图像的视觉效果，提高了图像解译的精度。
