Abstract

The relationship between DBH and crown width were investigated for independent and well-growing trees without disturbance in the natural stand of Betula alnoides in Xishuangbanna.It was found that the crown diameter ratio was about 22.4~71.3 times (the ratio of crown diameter to DBH) before DBH reached about 45 cm~50 cm.With the increase of DBH,the number of stands should be reduced accordingly.When the DBH reached above 45~50cm,the crown diameter ratio was basically stable,and the crown diameter ratio was about 19.1~22.6 times.
