随着遥感技术的快速发展，应用遥感影像特别是中高分辨率卫星影像进行农业工作成为遥感技术和农业工程发展的必然趋势，利用2011年RapidEye数据模拟中高分辨率卫星数据进行农作物种植面积提取精度提高技术研究，选取黑龙江省肇东市为研究区域，通过对中高分辨率卫星农作物提取结果进行系数扣除，对比分析三种扣除系数对肇东市水稻、玉米和大豆提高精度的效果，达到提高农作物提取精度的效果。结果表明：在种植结构相对单一区，利用地面样方扣除系数，精度提高显著；在复杂种植结构种植区，利用多尺度扣除系数精度提高显著。

With the rapid development of remote sensing technology ,the application of remote sensing images , especially high and moderate spatial resolution satellite images in agriculture became the inevitable trend of re‐mote sensing technology and the development of agricultural engineering .Trough 2011 RapidEye data to simu‐late high and moderate resolution satellite data ,researches improving the extraction accuracy of crop planting acreage .Taking Zhaodong City ,Heilongjiang Province as the study area .Through the coefficient deduction of the high resolution satellite crop extraction ,it improves the accuracy of crop extraction .The coefficient deduc‐tion used two kinds of sampling methods ,and three methods of coefficient deduction were put forward ,finally , three methods of coefficient deduction of Zhaodong rice ,corns and soybeans to improve the accuracy was ana‐lyzed .The results showed that :in the area of which planting structure was relatively simple ,using the ground sample deduction coefficient ,accuracy was improved significantly ;in the area of which planting structure was complex ,the use of multi‐scale deduction coefficient accuracy was improved significantly .
