| فاکتور زیتوده یکی از روشهای کارآمد برای برآورد غیرمخرب زیتوده و کربن اندوخته در درختان و تودههای جنگلی است که در سالهای اخیر بهدلیل اهیمت مسایل مربوط به تغییر اقلیم، موردتوجه پژوهشگران این بخش قرار گرفته است. هدف پژوهش پیشرو، ارائه فاکتور زیتوده، نسبت زیتوده تاج به کل و فاکتور تعمیم زیتوده برای سه گونه جنگلی دستکاشت 20ساله صنوبردلتوئیدس (Populus deltoides Bartr. Ex Marsh)، توسکاییلاقی (Alnus subcordata C.A.Mey.) و دارتالاب (Taxodium distichum L. Rich) است. بدینمنظور از هر گونه، 12 پایه قطع و مشخصههای درصد رطوبت و وزن خشک بهتفکیک تنه، شاخه، سرشاخه و برگ اندازهگیری شد. براساس نتایج، فاکتور زیتوده صنوبردلتوئیدس، توسکاییلاقی و دارتالاب بهترتیب برای شاخه 036/0، 007/0، 006/0، سرشاخه 055/0، 017/0، 024/0 و برگ 041/0، 006/0، 031/0 تن بر مترمکعب بود. نسبت زیتوده تاج به کل در گونه صنوبر دلتوئیدس بهطور معنیداری کمتر از دو گونه دیگر بود. مقادیر فاکتور تعمیم زیتوده برای صنوبر دلتوئیدس، توسکاییلاقی و دارتالاب بهترتیب 499/0، 554/0 و 621/0 تن بر مترمکعب محاسبه شد که اختلاف آنها معنیدار بود (05/0> ρ). گرچه این ضرایب ساده و کارآمد هستند، اما استفاده از آنها در جنگلکاریهای دیگر باید با احتیاط انجام شود، زیرا درصورت تفاوت بسیار زیاد تودهها، ممکن است برآوردها اریب باشند. | ||

| چکیده [English] | ||
| Biomass factor is one of the efficient methods for non-destructive estimation of biomass and carbon storage in forest stands. To fulfill the existing lack of biomass data in plantations of Northern Iran, this study derived biomass factor (BF), crown biomass to aboveground biomass ratio (R) and biomass expansion factor (BEF) coefficients for three tree species of Eastern Poplar (Populus deltoides), Caucasian Alder (Alnus subcordata)and Bald cypress (Taxodium distichum) across a 20-years old plantation. For each species, 12 individual trees were felled down. Then the dry weigh of stem, branches, twigs and leaves were separately measured for each tree. The BF values for Eastern Poplar, Caucasian Alderand Bald Cypress were 0.036, 0.007, 0.006 Mg m-3 for branch, 0.055, 0.017, 0.024 Mg m-3 for twigs and 0.041, 0.006, 0.031 Mg m-3 for leaves, respectively. Compared to the other two species, the R value forEastern Poplarwas significantly lower. The BEF values were 0.499, 0.554 and 0.621 Mg m-3 for Eastern Poplar, Caucasian Alder and Bald Cypress, respectively. Although these coefficients are easy to apply and efficient for use, but using them for other plantations must be done with caution, because applying them for other plantations with different stand structure may result in a biased estimation. | ||
