Abstract

The difference significance of population structures of Phellodendron amurense,Juglans mandshurica and Fraxinus mandshurica in five natural distributions and researches correlation between tree height and DBH were studied.The results showed that tree height and DBH of three tree species in Taoshan forestry bureau was better than others.The correlation coefficient of tree height and DBH which was significant positive correlation was 0.875.Cubic was the best fitting function of tree height and DBH whose goodness-of-fit was 0.825.
