中文摘要：

MODIS是美国地球观测系统（EOS）装在Terra和Aqua卫星以及后继卫星上的中分辨率成像光谱仪，具有数据获取快、信息丰富和覆盖范围广等优点。近年来，随着信息化的快速发展和网络规模的日益扩大，MODIS用户数量不断增加，应用领域也更加广泛。文中对MODIS数据的来源、特性及其利用情况做了简要介绍，在火情监测方面的应用进行了拓展，并对其在森林防火方面的应用前景进行了分析。

英文摘要：

MODIS （ Moderate Resolution Imaging Spectroradiometer） is a key instrument installed on the Terra （EOS-AM） and Aqua （EOS-PM） satellites, with the characters of hierarchical data format, abundant information and its continence, quickly acquiring data and wide range of coverage, which has been widely used on observing earth surface. It is important in providing information on the location of a fire, its emitted energy, the flaming and smoldering ratio, and an estimate of area burned. It will be widely used in the future.
