EOS-MODIS数据在草地资源监测中的应用进展综述

Application Summary of EOS-MODIS data in the monitoring of grassland resources

简要介绍了美国对地观测系列卫星(Earth Observing Satellites,EOS)及其中分辨率成像光谱仪(Moderate Resolution Imaging Spectroradiometer,MODIS)数据在遥感方面的应用,总结了近年来MODIS数据在草地资源监测领域的研究成果,指出了利用MODIS数据进行监测与其他遥感卫星监测有不可比拟的优越性,着重介绍了MODIS数据在草地上进行植被动态、雪灾监测、火灾监测、病虫害监测等领域监测中应用的一般原理,并与应用甚高分辨率辐射仪(The Advanced Very High Resolution Radiometer,AVHRR)遥感监测进行对比。从理论上、技术上和实践上证明MODIS数据在各领域监测中的监测能力及可行性,目的在于为MODIS遥感监测工作提供一种有益的启示,以期为及时、准确监测预报提供借鉴和参考。

This paper introduced the American EOS and MODIS data and their applications in remote sensing, summarized the research achievement of MODIS data in grassland resources monitoring in recent years and its superiority comparing with other remote sensing satellites. Application principles of MODIS data in monitoring vegetation changes,snow and fire disasters, diseases and insect pests were introduced and compared with the application of AVHRR for remote sensing monitoring. The monitoring potential and feasibility of MODIS data in many fields were proved from theoretical, technical and practical aspects, to provide reference for timely, accurate monitoring and forecasting.
