基于GIS的黄淮海平原旱灾遥感监测研究

Drought Remote Sensing Monitoring for Huanghuaihai Plain Based on GIS

干旱作为自然灾害的一种，严重影响并限制着我国特别是北方地区农业生产的发展。该文主要研究利用遥感技术资料，基于ＧＩＳ技术，通过作物缺水指数模型监测旱情的方法。在黄淮海平原进行的实时监测表明，各种形式的结果与实际基本吻合，此方法可用于平原旱灾实时动态监测。

The monitoring results in Huanghuaihai Plain showed that both the drought distribution and states from calculating are coincided with the objective situation in Huanghuaihai Plain. A method to monitor drought using crop water stress index which is based on GIS technology combined with remote sensing data, graph and meteorological data was presented. The experiment results indicated the method can be used to monitor drought dynamically and timely in plain.
