冰川变化遥感监测综述

Review of remote sensing monitoring of glacier change

在全球变暖的大背景下,冰川变化的研究成为热点。该文介绍了遥感监测冰川范围变化的研究进展,总结了监测所需要的数据、数据预处理方法以及提取冰川面积的主要方法,比较了各种提取冰川范围方法的优劣,并在此基础上提出根据不同研究区实地条件,综合应用多种计算机分类方法是最为精确、实用的提取冰川范围的方法。

In the context of global warming, the study of glacier change has become a hot spot. This article describes the progress of remote sensing monitoring of glacier changes in the scope, summarizes the data needed to monitor data preprocessing methods and the main method of extracting the glacier area, compare the pros and cons of various extraction glacier extents. And on this basis, the article puts forward that the most accurate and practical method of extracting the glacier area, according to the different conditions on the ground in the study area, is the comprehensive application of variety of computer automatic interpretation method.
