The growth characteristics and correlation between the canopy index and growth characteristics of Populus×xiaohei plantation with different densities and stand ages were studied by the methods of sampling typical plot and allometric dimension analysis in Xuejiazhuang Forest Farm in Shanxi *** results showed that the DBHs of Populus×xiaohei plantations with various tree densities were *** Logistic growth model could accurately describe the tree height and DBH growth of Populus×*** fast growing period of tree height was obviously earlier and longer than that of *** dh value decreased with the increase of tree age,the DBH and the tree *** correlation coefficient between tree canopy and the DBH was increased with the tree *** DBH could be estimated by the canopy size in stands with low ***,the medium density Populus×xiaohei plantation should be selected for satellite image interpretation of tree canopy.
