利用NOAA／AVHRR资料监测干旱环境变化的研究

MONITORING ARID ENVIRONMENT BY NOAA/AVHRR DATA

本文介绍了利用ＮＯＡＡ卫星提取宏观范围干旱环境信息的方法。通过对植被、降水、地表、温度等诸多环境因子的遥感信息提取、分折，得出了一套利用气象卫星资料监测干旱环境的方法，并对绿洲植被，防护林生态效益，草地旱情等干旱区生境现象进行了监测评估，取得了较好效果。

The paper deals with drawing and interpreting NOAAsatellitedata aboutlargescale arid environment.Through comparison and analyses ofremote sensing data on environmental factors such as vegetation, precipitation and surface temperature,the authors have produced a series ofmethods for using meteorological satellite data to monitor arid environment.They also obtain good results in monitoring and assessing oasis vegetation,shelter forests and grassland of some areas of Xinjiang.
