不同开敞度条件下坡向对红松胸径和树高生长的影响
Effect of Aspect on the Diameter at Breast Height andHeight Growth of Pinus Koraiensis under the Different Opening Degrees
摘要
Abstract
The effect of aspect on the diameter at breast height (DBH) and growth height of plantation Pinus koraiensis trees under the canopy in secondary forests in Shanhetun,Maoershan and Fangzheng sites were studied.The results showed that the average DBH and average height of Pinus koraiensis in all experiment sites increased with the increasing opening degree in the same aspect (P<0.05),the average DBH and average height of Pinus koraiensisare were higher than those of other opening degree when opening degree was 2.0.The average DBH and average height of Pinus koraiensis in the southern aspect and the western aspect were larger than those in the eastern aspect and northern aspects in the same opening degree in each experiment site(P<0.05).关键词
