摘　　要：利用扫描仪获取标准图形,对ImageJ软件测定番茄叶面积的准确性进行了验证。发现不同的扫描分辨率(100、200和300DPI)对图形面积没有显著影响,200DPI的分辨率为较好的扫描参数。以番茄叶片为试材,对剪纸法与图像处理法进行比较,发现二者差异不显著。在此基础上,建立了一种扫描仪结合ImageJ软件测定番茄叶面积的方法。The accuracy of measuring tomato（Lycopersicon esculentum Mill.）leaf area by ImageJ software was confirmed through measuring scanned standard shape.There was no significant difference for area with 100,200 and 300 DPI.And 200 DPI was better.Two methods of paper-cutting and image processing for measuring tomato leaf area were compared and there was no significant difference.Based on the result,the method of measuring tomato leaf area with scanner and ImageJ software was established.
