| 摘 要： | 利用研究区域2001年NOAA-16卫星遥感资料和有关气象资料，根据作物生长发育季节，使用逐步回归的统计方法进行因子筛选，用选出的因子建立研究区域不同季节干旱遥感监测模型。用建立的模型对2002年该区春季干旱进行监测，结果表明：模型土壤湿度监测结果与地面观测结果较为一致，模型对该区干旱具有较好的监测能力。

| Abstract: | This paper establishes a remote sensing drought monitoring model for the investigated region based on the data of NOAA/AVHRR in 1991 and the meteorological observation data by applying a stepwise regression method.The data are obtained on clear days.The model has been used to monitor the spring drought in 2002,and results show that not only the spatial pattern but also the the degree of drought accord with the observations of soil relative humidity. |
