| 摘 要： | 在中国20年来泥石流遥感调查所取得成绩以及存在问题的基础上，尝试用新方法对泥石流进行研究，即采用遥感三维可视化方法调查泥石流。以汶川南沟为例，利用高精度的卫星遥感影像（quickbird）和1：50000的等高线，在erdas软件的支持下，实现了遥感影像三维可视化。并在此基础上对其应用——虚拟GIS飞行和泥石流流域内崩塌堆积物三雏遥感解译。实践证明由于遥感三维解译能全方位观察泥石流沟谷以及相关的地形地貌，所以其解译的准确率比传统二雏遥感解译率高。

| Abstract: | For 20 years,China has made Achievements in investigation of debris flow by remote sensing,but there are also many problems.new methods that the use of remote sensing three-dimensional visualization methods to investigate debris flow are introduced to conduct a study of the debris flow.Using high-precision satellite remote sensing images(quickbird)and 1:50 000 contour,the Nangou of the Wenchuan county has been taken as an example,three-dimensional visualization of remote sensing images can be realized under... |
