卫星遥感结合地面观测数据的土壤墒情监测分析系统

Soil moisture monitoring and analysis system based on satellite remote sensing and ground observation data

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 observations and remote sensing are currently the primary means of soil moisture informa-tion,and the combination of them may help to realize the fast and accurate monitoring of soil moisture. Inthis paper,the principles and methods for the soil moisture monitoring and analysis system based on satel-lite remote sensing and ground observation data are explained in detail and the system has been applied inthe Shandong province for the 2010-2011 drought. The results show that it can get the information quicklyand effectively on the temporal and spatial variation of droughts.
