玉米是我国主要的粮食作物之一,在我国北方地区占有举足轻重的地位。及时了解玉米种植面积、长势及产量,对于国家粮食政策的制定、价格的宏观调控以及对外粮食贸易都具有重要意义。遥感估产技术在农业发展中具有传统的统计方法不可比拟的优势,能及时客观地获得作物长势、产量等信息,特别是种植面积及其不同区域分布的信息,对于遥感估产玉米生产具有非常重要的作用。

As one of China＇s major grain crops, maize plays an important role in northern China. So it was greatly significant important to understand the maize acreage, growth and yield for the food policy development, macro-control of price and foreign food trade.
