| چکیده | ||
| افزایش نگرانی‌ها در زمینه گرمایش جهانی و تغییر اقلیم موجب شده است که به جنگل و خاک و توانایی آنها در ترسیب کربن به‌‌صورت پایدار توجه ویژه‌ای شود. جنگلکاری در اراضی بایر و مدیریت بهینه آن اثر زیادی بر افزایش ترسیب کربن خاک دارد، به‌طوری‌‌که خاک اکوسیستم جنگل در تعادل با پوشش درختی و گیاهی، مخزن اصلی کربن آلی است. به‌منظور بررسی مقدار ذخیره کربن در پارک جنگلی بام ملایر، واحدهای همگنی که گونه اقاقیا در آن حضور داشت، در روی نقشه مشخص شد و آماربرداری صددرصد از آنها انجام شد. پنج پایه از قطر متوسط هر طبقه قطری به‌عنوان نمونه برداشت و با استفاده از روش قطع و توزین، مقدار زی‌توده و در نهایت کربن آلی ذخیره‌شده و CO2 جذب‌شده محاسبه شد. برای تعیین مقدار کربن ذخیره‌شده در خاک، 40 نمونه از عمق‌های صفر تا 10 و 10 تا 30 سانتی‌متری تهیه شد. نتایج نشان داد که مقدار کربن آلی ذخیره‌شده سالانه در هر هکتار از توده موردتحقیق 1/6 تن است که از این مقدار 0/351 تن در زی‌توده اقاقیا و 1/253 تن در خاک ذخیره می‌شود. جذب سالانه CO2 در هر هکتار از توده به‌طور متوسط 5/87 تن است. همچنین نتایج آزمون دانکن نشان داد که میانگین ذخیره کربن در طبقات قطری موردبررسی از اختلاف معنی‌دار آماری برخوردار است. | ||

| چکیده [English] | ||
| The increasing concern on global warming and climate change has resulted in a special awareness to the potential of forest and soil for sustainable carbon sequestration. Therefore, an optimal management of afforestation established in barren lands notably influences the soil carbon sequestration which consequently turns the forest coverage (and underlying soil) to a major organic carbon sink. This study aims to quantify the amount of carbon storage in a selected area afforested Black Locust in Malayer, Iran. Initially, the land units including Black Locust trees were indicated on map polygons, followed by the measurement of all trees within the polygons. Then, five samples in each diameter class were selected, within which the amount of biomass, carbon storage and co2 uptake were estimated. To determine the amount of stored carbon in the soil, samples were collected from two soil depths of 0-10 and 10-30 cm. The amount of the annual sequestrated carbon in biomass and soil was then estimated to be 0.351 and 1.253 tons per ha, respectively. In addition, the annual co2 uptake was 5.87 tons per ha. The results indicate significant differences between the amount of carbon storage in different diameter classes of R. pseudoacacia trees. | ||
