摘要
利用NOAA卫星AVHRR通道1、2,计算植被指数和通道4的亮温,运用植被供水指数法监测辽西地区土壤干旱情况,结果表明,与实地的早情分布基本一致。
Vegetation index data is calculated from NOAA satellite visible and infrared data, with brightness temperature data from satellite channel No.4. Soil drought was monitored with the method of vegetation supply water index in the west of Liaoning. It was shown that the results is like the real situation.
