基于EOS/MODIS的几种植被指数

Introduction of Several Vegetation Indices Based on EOS / MODIS

从EOS卫星的中分辨率光谱仪MOD IS出发,选取已定义的40多种植被指数中最常用的几种指数进行重点介绍,并对已有的研究成果进行总结,指出优劣,为实际业务应用和科研提供参考。针对MOD IS的植被指数合成算法进行了详尽介绍,以将其与AVHRR植被指数的合成算法区别开来。结合西北当前在MOD IS植被指数方面的研究和应用情况进行了总结。

Starting from the EOS satellites MODIS medium-resolution spectrometer, several commonly used vegetation indices（VI） were intro- duced emphatically, the research results were summarized, and the advantages and disadvantages were pointed out which can provide a refer- ence for practical business application and scientific research. In addition, the synthesis algorithm about MODIS VI was introduced in detail in order to be distinguished from AVHRR VI synthesis algorithm. Finally, the current research and application of MODIS VI in northwest was summarized.
