摘　　要：针对华北地区旱情导致小麦减产的问题,提出了利用Landsat遥感影像信息,结合小麦生长关键时期的降雨量以及种植区距离灌溉水源的位置关系,建立小麦估产模型,通过降雨预报信息估算小麦单产产量,并将其应用在作物种植选择方面,以提高农田的产值与农民的经济效益。In view of the phenomenon that the drought in north China causing wheat production reducing, using Landsat remote sensing image information, combined with the rainfall of the key period of wheat growth and the distance between planting area and irrigation water source, this paper established the wheat yield estimation model. The paper used the rainfall forecast information to estimate the next year's wheat production, and used it to choice plant, in order to improve the crop output value of the farmland and the economic benefits of farmers.
