Abstract: The calculation results based on 84 samples show that the crown leave area is proportional to the crown profile area.The ratio Kincreases with increasing growth rate of the growing frees.The dominant tree has the biggest value of the ratio K,which is a little bigger than 1.0.The potential use of the solar energy by the crown is positively correlated tothe crown profile area.
