观光木人工林生长规律的初步研究

对27年生观光木人工林的生长规律进行研究的结果表明，观光木人工林在幼林阶段树高生长较快，生长高峰期出现在第4年，之后逐渐下降；在第12～20年时保持较高且稳定的生长态势；胸径总生长量随着林龄的增加而增大，前7年为观光木人工林的胸径速生期；材积的增长一直呈上升阶段，且随着林龄的增大而加快，在27年达到材积数量成熟。

Study on Growth Law of Tsoongiodenron odorum Plantation

The growth law of 27 -years -old Tsoongiodenron odorum plantation was studied. The result showed that the tree height of Tsoongiodenron odorum plantation grew faster when it was young, growth peak appeared in the fourth year, and then declined, and the tree height kept high and stable growth trend. With the growth of total DBH plantation age increased, the fast -growing DBH period of Tsoongiodenron odorum was 7 years before. Volume growth has been rising stage, and with the increase of plantation age faster in 27 years. The Tsoongiodenron odorum reached volume mature.
