چکیده

ترکیب و تنوع جوامع گیاهی و جانوری در طول زمان با تغییر شرایط محیطی و در اثر آشفتگی‌ها تغییر می‌کند. در این پژوهش تأثیر آشفتگی بر ساختار جنگل در ذخیره‌گاه دارمازو واقع در منطقه شینه‌قلایی استان لرستان بررسی شد. به این منظور 8 توده جنگلی دچار رانش زمین با مجموع مساحت 5/4 هکتار شناسایی و در ادامه موقعیت و مشخصات کمی و کیفی (در 4 طبقه آسیب‌دیدگی) درختان ثبت شد. سپس تغییرات تراکم، تنوع گونه‌ای و پراکنش درختان ارزیابی شد. بر‌اساس نتایج، پس از آشفتگی و رانش زمین، نیمی از درختان در طبقات آسیب‌دیدگی متوسط و شدید قرار دارند و 2/17 درصد از پایه‌های درختی و 41/4 درصد از مقدار تاج‌پوشش توده‌ها از بین رفته که بیشتر مربوط به درختان جوان بوده است. در مقوله شاخص‌های ساختاری، تنوع گونه‌ای و آمیختگی روند کاهشی و شاخص‌های اسمیت- ویلسون و زاویه یکنواخت افزایش داشته‌اند. با توجه به نتایج، اگرچه به لحاظ آماری اختلاف معنی‌داری در شاخص‌های ساختاری مشاهده نشد، اما خشک‌سالی‌های پی‌در‌پی، بارش‌های تند و نامنظم، تخریب و به‌دنبال آن رانش زمین در مدت زمان کوتاهی منجر به تغییرات آشکار در ساختار جنگل شده است که متأسفانه این روند همچنان ادامه دارد. از‌این‌رو، ضروری است با اقدامات حفاظتی بیشتر و احیای جنگل، به‌ویژه در کانون‌های آشفتگی، زمینه کاهش یا توقف نابودی این زیست‌بوم ارزشمند را فراهم کرد.

چکیده [English]

The composition and diversity of plant and animal communities change over time due to environmental changes and disturbances. In this study, the impact of short-term disturbance on forest structure in the Daramazu Reserve, located in the Shineh Qallaei region of Lorestan Province, was investigated. For this purpose, 8 forest stands affected by landslides with a total area of 4.5 hectares were identified, and the quantitative and qualitative characteristics of trees (in 4 damage classes) were recorded. Subsequently, changes in tree density, species diversity, and distribution were evaluated. Based on the results, after the disturbance and landslides, half of the trees are in moderate and severe damage classes, and 17.2% of tree bases, as well as 4.1% of canopy cover, have been lost, mostly affecting young trees. Regarding structural indices, species diversity and evenness had a decreasing trend, while the Smith-Wilson index and uniform angle index increased. Despite not observing statistically significant differences in structural indices, the combination of consecutive droughts, irregular and intense rainfall, degradation, and subsequent landslides has led to noticeable changes in the forest structure over a short period of time, and unfortunately, this trend continues. Therefore, it is essential to implement further conservation measures and forest restoration, especially in areas affected by disturbances, to mitigate or halt the destruction of this valuable ecosystem.
