摘要
在漾濞县地质灾害调查中,应用"3S"技术,建立了三维遥感地形,突破了传统调查的方法限制,发挥其逼真、形象、宏观、真实的特点,取得了较好的效果.研究发现:利用遥感技术结合野外考察,可以提取引发泥石流的主要因素并解译出灾害点信息,是一种快速、直观的好方法;通过对遥感数据各波段之间的特征统计分析和相关性分析,选取了ETM+741作为地质灾害解译的最佳波段组合.
Using ＂3S＂technology in the survey of Yangbi County＇s Geological Hazards,three-dimensional remote sensing terrain was established,breaking the limit for traditional methods in the survey,with their realistic,vivid,macroscopic,features,and achieved good results.It＇s found that： the use of remote sensing technology combined with fieldworks,can extract the main factors of debris flow and interpreting information which is a fast and intuitive way;by analysis remote sensing data,the features of each and the related statistical,selected ETM＋741 as the best interpretational combination for geological disasters.
