چکیده

تحقیق حاضر با هدف، برآورد زی‌توده، ذخیره کربن و شاخص سطح برگ گونه زالزالک (Crataegus aronia L.) در جنگل‌های‌ سرطاف شهرستان ایلام انجام شد. بدین منظور و با استفاده از روش نمونه­برداری تصادفی، 30 اصله درخت زالزالک انتخاب و متغیرهای قطر یقه، ارتفاع درخت، طول تاج، قطر بزرگ و کوچک تاج و متوسط قطر تاج اندازه­گیری شد. سپس برگ­های یک‌چهارم تا یک هشتم تاج درختان نمونه جمع­آوری شد. پس از خشک ‌کردن در داخل آون، وزن خشک برگ­ها تعیین شد. پس از سوزاندن مقدار کافی از برگ­های خشک‌شده در کوره الکتریکی، وزن مواد آلی و مقدار کربن برگ­ها به‌دست آمد. نتایج نشان داد که متوسط زی‌توده برگ، ذخیره کربن برگ، مقدار جذب دی‌اکسید کربن از جو به‌ترتیب 18/99، 61/46، 59/170 کیلوگرم در هکتار به‌دست آمد. متوسط شاخص سطح برگ گونه زالزالک برای هر درخت 08/9 و در هکتار منطقه 095/0 محاسبه شد. نتایج بررسی روابط آلومتریک با استفاده از روابط رگرسیونی مدل‌های مختلف نشان داد که همبستگی مثبت و معنی­داری بین متغیر متوسط قطر تاج با متغیرهای زی‌توده و شاخص سطح برگ درختان زالزالک در جنگل­های ایلام وجود دارد. به­طور کلی، نتایج حاصل از این تحقیق توانایی اندازه­گیری زی‌توده، ترسیب کربن و شاخص سطح برگ گونه زالزالک را با استفاده از معادلات آلومتریک نشان می‌دهد.

چکیده [English]

The objective of this research was to estimate the biomass, carbon storage and leaf area index of hawthorn species (Crataegus aronia L.) in Sartaf forests of Ilam city. For this purpose, using random sampling method, 30 hawthorn trees were selected and variables of collar diameter, tree height, crown length and large and small diameter of the crown were measured. Then, the leaves from 1/4 or 1/8 of the crown of sample trees were collected. After drying the leaves in the oven, the dry weight of the leaves was determined. After burning a sufficient amount of dried leaves in an electric oven, the weight of organic matter and carbon content of the leaves were obtained. The weight method was used to calculate the leaf area index. The results showed that the average leaf biomass, leaf carbon sequestration, and carbon dioxide absorption from the atmosphere were 99.18, 46.61, and 170.59 kg per hectare, respectively. The average leaf area index of hawthorn species was calculated as 9.08 for each tree and 0.095 per hectare in study area. The results of allometric relationships using different regression models showed a positive and significant correlation between the variable of mean crown diameter with the variables of biomass and leaf area index of hawthorn trees in Ilam forests. In general, the results of this research show the ability of using allometric equations to measure biomass, carbon sequestration, and leaf area index of Crataegus aronia.
