This article introduced the method that determined root length,cross-sectional area and average root diameter through dealing with root images by ARCVIEW.The images were shot by digital camera.Then determination error was discussed from resolution of images,location of scale,inclining angle of roots and man-made factors and so on.It was found that there was few effect of resolution of images and man-made factors on the result measured and location of scale and inclining angle of roots would affect more.But on the condition the results precision would meet the research.Compared with others,the method procedure was simple,accurate and quick.Furthermore it could be used in undamaged dynamics research of root system.
