Présentation
The desertification in China, where losing about a million acres a year to desertification, greatly influences the environment not only of China but of all Asia. In order to stop the trend of desertification, various anti-desertification combats, such as afforestation et al. were completed. Elm(U. pumila L.), which is widely distributed in the northern China, is considered as the most valuable species in sandy area by wood utilization and the characteristics of promoting vegetative diversity. In this study, six elm trees have been selected to investigate the radial variation patterns of tree ring width and cell dimensions, such as : fiber length(FL), vessel element length(VEL), fiber increment and vessel lumen diameter(VLD)
