摘要

对伊朗森林234棵受伤树木的伤口愈合率(WHR)进行了调查，发现伤口愈合率在6.4 ~ 24.0 mm·yr -1之间。树种、坡向、海拔、伤龄和伤型对水净比有显著影响。白蜡树(24 mm·yr -1)、亚心桤木(18.9 mm·yr -1)和东方Fagus (17.9 mm·yr -1)的WHR平均值显著高于槭(15.7 mm·yr -1)、槭(14.6 mm·yr -1)、桦木(13.7 mm·yr -1)和秋海莲(6.4 mm·yr -1)。此外，北坡的平均水热比(17.5 mm·yr -1)显著高于南坡。此外，对树木生长有积极影响的参数对伤口愈合率也有类似的影响。5岁、10岁和15岁伤口的whr分别为19.3、16.9和10 mm·yr -1。离地高度越高，伤高比越高。水平创面的WHR (18.4 mm·yr -1)显著高于垂直创面。冠层封闭度为60 ~ 80%的林分，其净水比最高。随缠绕宽度的增加，腰宽比减小。创伤会影响未来的收入，减少树木的数量，而这些树木可能提供更高质量的锯木和贴面原木。

Healing rate of logging wounds on broadleaf trees in Hyrcanian forest with some technological implications.

The wound healing rate (WHR) was investigated in 234 wounded trees in Iranian forests and was found to range from 6.4 to 24.0 mm·yr -1 . Tree species, slope aspect, elevation, wound age, and wound type had significant effects on the WHR. The mean of the WHR in the Fraxinus excelsior (24 mm·yr -1 ), Alnus subcordata (18.9 mm·yr -1 ) and in the Fagus orientalis (17.9 mm·yr -1 ) were significantly higher than in the Acer insigne (15.7 mm·yr -1 ), Acer cappadocicum (14.6 mm·yr -1 ), Carpinus betulus (13.7 mm·yr -1 ), and Tilia begonifolia (6.4 mm·yr -1 ). In addition, the mean of the WHR on northern slopes (17.5 mm·yr -1 ) was significantly higher than on southern slopes. Moreover, the parameters that positively influenced tree growth showed a similar effect on the wound healing rate. The WHRs of 5-, 10- and 15-year-old wounds were 19.3, 16.9 and 10 mm·yr -1 , respectively. The WHR increased the higher the wound from ground level. The WHR for horizontal wounds (18.4 mm·yr -1 ) was significantly higher than for vertical wounds. The highest WHR was estimated in a stand with a canopy closure of 60-80%. The WHR decreased according to increasing wound width. Wounds affect future income, lowering the number of trees that potentially provide a higher quality of saw and veneer logs.
