摘要
干旱是威胁我国及世界农业发展的自然灾害之一,遥感技术已经成为监测旱情的重要手段。本文回顾了近些年来遥感监测旱情的研究进展,并总结了国内外常用的模型,着重从热惯量法,冠层温度法,植被指数法以及微波遥感等几方面做出评述,并对遥感监测旱情的下一步发展提出展望。
Drought is one of the nat ural disaster that threaten our agricultural development as well as the world's .Rem ote sensing technic has become the important means of drought monitoring. This paper reviews the advances of drought moni toring by remote sensing of thes e years and summarize s the models in common use inside and o utside,especially reviews the meth ods such as Thermal Inertia,Canopy Temperature ,Vegetation I ndex as well as Microwave Remo te Sensing,ect.The paper also bring forward the ex-pectation of the following developm ent of drought monitoring by remote s e nsing.
