摘    要:以农业干旱发生时所引起的若干地表特征变化为依坦,分别从土壤水分、植被水分、冠层温度和作物形态4方面,对现有主要农业干旱遥感监测模型进行归纳总结,分析了各种模型的优缺点,以及各自的适用范围。其中土壤水分变化类指数比较适宜于农业旱情预警及土壤干旱型农业旱情的监测;冠层温度变化类指数不仅适宜于农业旱情预警,更适宜于农业旱情监测;作物形态及绿度变化和植被水分变化类指数,较适宜于农业旱灾的预警以及灾后评估。

关 键 词:农业干旱  遥感  监测模型

Abstract:Agricultural drought occurs in a number of surface features caused by changes in the basis, respectively, from soil moisture, vegetation moisture, temperature and crop canopy shape four aspects of the existing major agricultural drought remote sensing monitoring model, summarized, analyzed the various models the advantages and disadvantages, and their respective application. Where soil moisture class index suitable for agricultural drought warning and drought agriculture soil drought monitoring; canopy temperature class index is not only suitable for agricultural drought warning, more suitable for agricultural drought monitoring; crop morphology and vegetation greenness change and water change index are more appropriated for agricultural drought early warning and disaster assessment.
Keywords:agricultural drought  remote sensing  monitoring models
