Abstract: On the basis of summarizing the measures of tree-ring width,this paper puts forward a new method to measure tree-ring width using digital image form flatbed scanner and computer.Five tree-ring discs were measured respectively with FSDI and Tree Ring Analysis System.According to TRAS,the result of verifying the precision of the new method shows that FSDI can satisfy the demand of tree-ring research.The synthetic comparison between both methods’ efficiency and economic cost also indicates that the new method has advantages of simple measure,easy availability of equipment,low economic cost and so on.

Key words: tree-ring width, digital image, measurement method
