遥感墒情监测方法研究综述

Research on Soil Moisture Monitoring Methods with Remote Sensing Technology

随着遥感技术的发展,遥感应用不断深化.从遥感数据中挖掘地表农学、生态等参数成为研究热点.本文总结了国内外利用遥感数据进行墒情反演的方法,包括植被指数法、温度指数法以及微波遥感法等,指出了这些方法的应用概况、适用条件、存在问题,对土壤墒情监测具有一定的指导意义.

With the development of remote sensing technology,the application of it deepened daily.Getting parameters of the earth surface about agriculture,ecology from remote sensing data became a hotspot.This paper summarized moisture inversion methods using remote sensing data both at home and abroad,which included vegetation indexes,temperature indexes,as well as microwave remote sensing.The paper also pointed out the general situation in application,the applicability and the problems with these methods and so on.It could provide some proposal in soil moisture monitoring.
