Abstract: In ths paper,taking disks of Cyclocarya paliurus trunk at 1.3 m as the research object,through the wood anatomic method measurement was conducted on its growth round fiber length,width,aspect ratio,cavity diameter,wall thickness,wall cavity ratio and tube length,width,aspect ratio,cavity diameter,wall thickness and wall cavity ratio,and studies were made of the various indicators along with the growth ring radial variation patterns of age growth.The results showed that Cyclocarya paliurus fiber length and fiber length-width ratio along with the growth of the age of growth ring overall had a growing radial variation law; And fiber width,fiber wall thickness,diameter,fiber wall cavity ratio along with the growth of the age of growth ring exhibited no obvious variation regularity.Cyclocarya paliurus catheter in the wall thickness,length,width of catheter,guide catheter lumen diameter along with the growth of the age of growth ring radial variation regularity of overall increased; Catheter length-width ratio,guide wall cavity ratio along with the growth of the growth ring of age had no obvious variation rule.
