摘要
以长春净月潭遥感试验区和吉林省梨树县为主要试验区，研究建立玉米遥感估产模式。利用多种图像处理方法提取玉米播种面积，建立单产估产模型，对试验区１９９２年玉米产量进行了估算预报，结果较好。
In this paper,we discuss a number of general issues that pertain to application patternof maize yield estimation by remote sensing.We select sarnple sites of Changchun Jingyue-tan remote sensing test site of chinese academy of sciences and Lishu county of Jilinprovince. We mainly explore two parts:(1)extraction of information of different growingcondition of maize and area calculation of maize of different growing conditions.(2)vieldestimation models for maize.
