遥感旱灾模型综合分析

SYNTHETICAL ANALYSIS OF DROUGHT MODELS FOR REMOTE SENSING

本文在野外实验的基础上，对遥感旱灾模型进行综合分析和评价。运用四年的实地观测数据，校正了旱灾模型中的待定系数，使其能用于ＮＯＡＡ气象卫星对旱情的监测。对复杂的蒸散模型简化的可行性进行了尝试性研究。

In this paper,synthetical analysis and assessment of drought models are made based on the field experiment of remote sensing.The data observed in field is used to calibrate the coefficients in these models.NOAA AVHRR data and these models used for monitoring the drought of wheat field.The complex evaporational model is simplified also.
