| بلوط ایرانی (Quercus brantii Lindl.) یکی از مهم‌ترین گونههای اکوسیستم جنگلی زاگرس است که زادآوری طبیعی آن به یک چالش تبدیل شده است. این مطالعه به‌منظور بررسی ترکیب و مؤلفه‌های تنوع گونه‌ای (آلفا، بتا و گاما) پوشش گیاهی در لکه‌های دارای زادآوری و با زادآوری ضعیف جنسی بلوط شمال شهرستان ایلام انجام شد. ده قطعه‌نمونه 100 متر مربعی از هر کدام از حالت‌ها به‌صورت تصادفی انتخاب شد و در هر لکه چهار قطعه‌نمونه (1×1 متر) برای شمارش گونههای گیاهی پیاده شد. بر اساس آزمون مونت‌کارلو، در لکه‌های دارای زادآوری و با زادآوری ضعیف به‌ترتیب 23 و 13 گونه شاخص (به‌ترتیب از بین 109 و 58 گونه) مشخص شد. بر اساس تحلیل تطبیقی قوس‌گیری‌شده (DCA)، دو لکه مورد بررسی از نظر ترکیب پوشش گیاهی متفاوت بودند. تروفیت‌ها و همی‌کریپتوفیت‌ها شکل زیستی غالب در هر دو لکه بودند. در هر دو لکه، مؤلفه‌های مختلف تنوع گونه‌ای در لکه‌های دارای زادآوری بهطور معنی‌داری بیشتر از مقادیر آنها در لکه‌های با زادآوری ضعیف بود. در هر دو گروه لکه، تنوع درون واحدهای نمونه (آلفا) در مقایسه با تنوع بین واحدهای نمونه (بتا) دارای سهم بیشتری از تنوع کل (گاما) بود. بهطور کلی می‌توان بیان کرد که ترکیب و تنوع گونههای گیاهی می‌توانند به‌عنوان شاخص‌های زیستی مناسبی برای پایش ناهمگنی عرصه در لکه‌های زادآوری بلوط ایرانی مورد استفاده قرار گیرند. | ||

| Brant`s oak (Quercus brantii Lindl.) is one of the most important species of Zagros forest ecosystem that it’s natural regeneration has become a challenge. This study aimed to investigate the composition and species diversity component (alpha, beta and gamma) of indicator plant species in well and poorly seed-origin oak regenerated spots in north of Ilam city. In this study, ten 100-m2 plots were randomly selected from each of the spots. Four sample plots (1 × 1 m) were established in each spot for counting the number of plant species. The Monte Carlo test detected 23 and 13 indicator species from 109 and 58 species in well and poorly seed-origin oak regenerated spots, respectively. Based on Detrended Correspondence Analysis (DCA), two spots were different in terms of species composition. The dominant life forms in the two spots were therophytes and hemicryptophytes. The results showed that different components of species diversity i.e. alpha, beta, and gamma were higher in well seed-origin oak regenerated spots than in poorly regenerated spots. In both spots, diversity within the sample units (alpha) compared with diversity between sample units (beta) had a greater contribution in total diversity (gamma). In general, it can be concluded that the composition and diversity of plant species could be used as a bioindicator for monitoring the heterogeneity of oak regenerated spots. | ||
