3.
Through the data obtained with remote sensing image and the data from ground meteological station,the farmland evapotranspiration was estimated and the crop water stress index (CWSI) was figured out so as to monitor the drought situation in Huanghe, Huaihe and Haihe plains.
研究了在黄淮海平原旱灾监测中，通过遥感数字图象获得的数据和地面气象站资料估算农田蒸散进而计算作物缺水指数来监测旱灾的方法，以及为此而进行的对气象数据的最优插值处理，并发展了确定最优插值所需初值的线性插值模型，在ＧＩＳ的支持下实现了图象、图形、数据的一体化。
