| زادآوری جنسی از مهمترین عوامل مؤثر بر بقا و پایداری جنگل‌ها محسوب می‌شود که تحقق آن تحت تأثیر مجموعه‌‌ای از منابع و شرایطی قرار دارد. در این بین، خردزیستگاه اهمیت زیادی در استقرار زادآوری دارند. پژوهش پیش‌‌رو با هدف شناسایی نقش خردزیستگاهها در بخشی از جنگل‌‌های زاگرسمیانی منطقه بابایادگارشهرستان دالاهو در استان کرمانشاه انجام شد. در منطقه مورد مطالعه، 372 قطعه‌‌نمونه به ابعاد 5 × 5 متر مربع که تعیین‌کننده خردزیستگاههای درختی مختلف شامل برودار (.Quercus brantii Lindl)، مازودار (.Q. infectoria Oliv)، زالزالک (.Crataegus pontica C. Koch)، آمیخته و فضای باز بدون درخت) بودند، در امتداد هفت ترانسکت نمونه‌‌برداری شدند. در هر قطعه‌‌نمونه، ویژگی‌‌های زیست‌‌سنجی درختان، زادآوری جنسی آنها و عمق لاش‌برگ خاک اندازه‌‌گیری شد. نتایج نشان داد که خردزیستگاه مازودار بیشترین میانگین قطر برابر سینه و خردزیستگاه آمیخته بیشترین تعداد جست را داشتند. همچنین، بیشترین میانگین تنوع زادآوری در خردزیستگاه برودار مشاهده شد. نتایج تجزیه‌وتحلیل چند‌‌متغیره نشان داد که مهمترین عوامل تفکیک خردزیستگاهها تنوع و وفور درختان بود که بیشتر از 83 درصد خردزیستگاههای مورد مطالعه رابه‌‌درستی تفکیک کردند. درمجموع، براساس نتایج پژوهش پیش‌‌رو مشخص شد که خردزیستگاهها و ویژگی‌‌های آنها، نقش کلیدی در استقرار و تنوع زیستی زادآوری و درنتیجه، ساختار آینده توده‌‌های جنگلی دارند، بنابراین توجه به آنها می‌‌تواند تأثیر به‌سزایی در موفقیت برنامه‌‌های احیایی جنگل‌‌های زاگرس داشته باشد. | ||

| چکیده [English] | ||
| Sexual regeneration is amongst the most important factors that affect the survival and sustainability of forests. It is controlled by the total resources and conditions representing the role of microhabitats in the establishment of the regeneration. Thus, identifying the role of microhabitats on the establishment and diversity of regeneration is of great significance. Therefore, the present study was conducted in a central part of the Zagros region in Baba-Yadegar forests of Dalahoo County, Kermanshah province. A total of 372 5 × 5 plots were established with respect to the tree microhabitats, including Quercus brantii Lindl., Q. infectoria Oliv., Crataegus pontica C. Koch., mixed and open spaces (with no trees) along 7 transects. In each plot, the biological characteristics of the trees were measured together with sexual regeneration and soil litter depth. The results showed that the mean value of DBH was significantly higher for Q. infectoria microhabitat compared to other microhabitats. In addition, the number of sprouts was significantly higher for mixed microhabitat compared to others. The highest species diversity of regeneration was observed in Q. brantii microhabitat. Furthermore, the result of multivariate analysis showed that the species diversity and abundance of trees in the microhabitat were the most important factors in the discrimination among microhabitats with over 83 percent of accuracy. It was concluded that the microhabitats and their characteristics play a major role in the establishment of tree species regeneration, diversity and consequently on the future forest structure that can contribute to the success of the restoration plans in the Zagros forests. | ||
