| 摘 要： | 介绍了ETM＋图像与ASAR数据在探测浅层地下水方面的优缺点，并通过对内蒙古阿拉善左旗地区遥感资料的处理，研究了光谱图像与雷达数据融合后在探测浅层地下水方面的应用效果。研究表明该方法虽不能精确地探测到浅层地下水的埋深与范围，但对掌握宏观区域上浅表层地下水的分布较之单一数据源具有更快速、更直观的效果。 |

| Abstract: | The advantages and disadvantages of ASAR and ETM ＋ data technology on detecting shallow groundwater are presented. The application of ASAR and ETM ＋ data technology is researched by treating the remote sensing materials of Alashanzuoqi area in Neimenggu. The results show that the technology is more obvious and quicker to demonstrate the coverage and distribution of the shallow groundwater on the macro level although it still cannot detect the accurate site and depth of the groundwater. |
| Keywords: | ASAR data image fusion shallow groundwater remote sensing interpretation |
