Populus×xiaohei%growth characteristics%canopy%correlation
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 Province. The results showed that the DBHs of Populus×xiaohei plantations with various tree densities were different. The Logistic growth model could accurately describe the tree height and DBH growth of Populus×xiaohei. The fast growing period of tree height was obviously earlier and longer than that of DBH. The dh value decreased with the increase of tree age, the DBH and the tree density. The correlation coefficient between tree canopy and the DBH was increased with the tree densities. The DBH could be estimated by the canopy size in stands with low density. Therefore, the medium density Populus×xiaohei plantation should be selected for satellite image interpretation of tree canopy.
