| 摘 要： | 秸秆焚烧容易污染空气,影响交通。常规秸秆焚烧监测难度较大,而卫星遥感数据具有覆盖面广,时效性强、分辨率高等优点,有利于秸秆焚烧监测工作的进展。本文将介绍如何使用MODIS数据提取秸秆焚烧火点的算法。在算法实现上采用交互式数据语言IDL（Interactive Data Language）进行实现,大大缩短了人机交互时间,提高了秸秆焚烧点自动提取的响应速度,从而提高工作效率,促进秸秆焚烧监测工作的开展。

| Abstract: | Crop straw burning is easy to pollute air and impact traffic safety. It is difficult to monitor straw burning by conventional way. However, remote sensing data have the advantage of wide coverage, better time effectiveness and high resolution. So it is beneficial to the development of monitoring straw burning. This paper introduced the algorithm of extracting crop straw fire using MODIS image. And then use interactive data language （IDL） to implement the algorithm. That will shorten the time of human-computer interaction, and also improve the response speed of automatic extraction of crop straw fire. Thus, the work efficiency will he improved, and it will strongly promote the monitoring crop straw burning work. |
