چکیده

منطقه مورد مطالعه واقع در سری چلیر جنگل آموزشی- پژوهشی خیرود در سال 1377 دچار حریق سطحی با شدت زیاد گردید و پس از گذشت 7 سال از وقوع آتش‌سوزی، به‌منظور بررسی اثر آتش‌سوزی بر رویش قطری درختان راش و ممرز اقدام به انجام این تحقیق شد. بعد از پیمایش سراسر مناطق سوخته و شاهد، تعداد 60 نمونه مغزی با استفاده از مته سال‌سنج، از دو گونه راش و ممرز (هرکدام 15 نمونه در هر یک از دو منطقه) تهیه گردیده و پهنای دایره‌های سالیانه مربوط به سالهای مختلف در هر نمونه اندازه‌گیری شد. مقادیر بدست‌آمده به‌تفکیک سالهای قبل و بعد از آتش‌سوزی و همچنین همبستگی آنها با داده‌های اقلیمی مورد تجزیه و تحلیل قرار گرفت. نتایج نشان داد که آتش‌سوزی سطحی اتفاق افتاده در این توده جنگلی تأثیر معنی‌داری بر رویش قطری راش نداشته، اما باعث افزایش معنی‌دار آن در ممرز گردیده است. همچنین میزان پهنای دایره‌های سالیانه در سالهای قبل از آتش‌سوزی با داده‌های اقلیمی همبستگی معنی‌دار داشته، درصورتی‌که در سالهای بعد از آن همبستگی مشاهده نگردید. بنابراین، ریشه تغییرات را می‌توان در عوامل دیگری به‌غیر از اقلیم مانند آتش‌سوزی جستجو کرد.

چکیده [English]

The study area is located in Kheyroud forest which was burned in 1998. This study was carried out to evaluate forest fire effect on diameter growth of beech (Fagus orientalis L.) and hornbeam (Carpinus betulus L.) after 7 years. After surveying whole burned and control area, 60 cores using increment borer were provided from both beech and hornbeam (15 cores were provided for each species in each area). Then sample’s ring growth width was measured. Statistical analysis was conducted on data which classified in years before and after fire. Furthermore, correlation between ring growth width and climatic data was tested. Results showed that the surface fire didn’t affect on beech but hornbeam ring growth was increased significantly. The correlation within ring growth width and climatic data had been recognized before fire but there was no correlation with years after that. Thus, other factors excluding climate such as fire could be considered as the change reasons.
