摘要
粮食作物的丰欠对国民经济影响很大,因而通过卫星遥感手段及时获得农作物的产量与面积信息,具有重要的政治意义和经济价值。本文总结了近十几年来国内外学者在遥感单产模式和作物面积信息提取方面的研究成果,提出了它们各自存在的优缺点及今后的发展方向。
Bumper or shorthall harvest of grain production has large influence on national economics. It is strategically important for timely and accurate crop production estimation from remotely sensed data. In this paper, yield models and methods of estimating crop area which were studied by scholars in recently ten years were summarized. Merits and demerits existed in various models and methods were put forward.
