地面观测、遥感是目前获得土壤墒情信息的主要手段,有效地将二者结合可实现土壤墒情快速、准确的监测。本文对卫星遥感结合地面观测数据的土壤墒情实时监测分析系统实现的原理、方法等进行了阐述,并应用该系统对山东省2010—2011年的旱情进行了遥感监测,结果表明其可以快速、有效地监测旱情的时空变化。
Ground observation and remote sensing are the main methods to get soil moisture information at present. Combining the two can effectively and quickly monitor soil moisture. This paper describes the principle and method of real-time monitoring and analysis system of soil moisture with satellite remote sensing and ground observation data, and uses the system to monitor the drought of Shandong Province from 2010 to 2011 by remote sensing. The results show that it can be quickly and effectively Monitoring the temporal and spatial changes of the drought.
