:溜砂坡是一种特殊的坡面堆积形式, 主要发生在较为干旱的花岗岩山区, 因其稳定性差, 溜砂坡活动较为频繁, 成为山区公路的重要灾害之一。以川藏公路然乌— 中坝段为研究区, 对溜砂坡的地形态和植被特征及其遥感影象特征进行了初步分析, 确定了溜砂坡的遥感解译标志, 并分析了溜砂坡和滑坡在遥感图像上的区别。将溜砂坡的遥感解译方法应用到川藏公路然乌— 中坝段, 查清了该路段的溜砂坡分布及其危害。
Other Abstract

Sliding sand slope is a special slope accumulation w hich is normally dist ributed in grani tic mountains. Sliding sand slope becomes one of the mainly disasters for hig hw ay because the activity of sliding sand slope is frequent for the instability of the slope .The topographical features , vegetation characteristics and their image characters are analy zed .The identifications of interpretation of sliding sand slopes is designed based on the image characters .The differences of sliding sand slopes and landslides on the image are analy zed .As a case study , the method of interpretation of sliding sand slope by remo te sensing is applied in the sect ion of Ranwu-Zhongba in Sichuan-Tibet Highway .
