برآورد ضایعات چوبی در جنگل فندقلوی اردبیل با استفاده از نمونه برداری خطی

Woody Debris is structural and functional part on forest ecosystems and plays a key role in nutrition circulation and carbon storage in long time, tree regeneration and biodiversity conservation. For this reason, studies about investigation and determination of the amount, the method of measurement and spatial distribution of coarse woody are very important. To correct planning about coarse woody in Fandoghlou forests, at first febris we should measure the residues with a suitable statistical method. This study carried out with the aim of efficiency evaluation of line intersects sampling to estimate woody debris. To this, transect method applied based on probability, Huber, and Smalian approaches. Comparison the results of census and transect methods by using analysis of variance and Duncan test indicated that the transect method based on probability theory was the best. On the other hand, modeling the woody debris distribution carried out regard to ground slope and distance from recreation area based on multiple linear regression method.
