农业干旱监测方法研究

农业干旱是农作物生产的主要自然灾害之一,建立有效的干旱监测模型,具有重要的现实意义。文章从基于站点数据和基于遥感数据两个方面对现有的农业干旱监测方法及对应的典型干旱监测指标进行了系统性地分析总结,并从不同波段的角度阐明不同遥感监测方法的原理及对应监测指标的适用性,在此基础上指出未来农业干旱监测的研究重点。

Agricultural drought is one of the main natural disasters of crop production,and therefore developing an effective drought monitoring method has important practical significance.This paper systematically analyzes and summarizes the agricultural drought monitoring methods and the corresponding typical drought monitoring indices from the perspective of in-situ data and remote sensing data,and expound the monitoring principles of different remote sensing monitoring methods and the applicability of their corresponding monitoring indices from the perspective of different bands.On this basis,we point out the research emphases of agricultural drought monitoring in the future.
