چکیده
فلور هر منطقه بازتابی از تاثیرعوامل مختلف اکوسیستم در طول دوران مختلف زمین‌شناختی است. شناسایی گیاهان برای تعیین توان طبیعی هر منطقه و کاربری آن بسیار حائز اهمیت است. هدف از مطالعه حاضر بررسی فلوریستیکی منطقه حفاظت‌شده بصیران شهرستان اقلید در استان فارس است. برای انجام این پژوهش، برداشت نمونه‌های گیاهی به روش پیمایشی و ترانسکت خطی انجام گرفت. با جمع آوری 250 نمونه گیاهی، 94 گونه از 70 سرده مربوط به 34 تیره شناسایی شد. بیشترین سهم گیاهان منطقه را دولپه‌ای‌ها با 82 گونه و59 سرده به خود اختصاص دادند. تک‌لپه‌ای‌ها دارای 12 گونه از 11سرده بودند. بزرگترین تیره Fabaceae با 13 گونه و بزرگترین سرده منطقه Astragalus با 7 گونه بودند. از میان نمونه‌ها، تعداد 16 گونه (17%) انحصاری ایران بودند. نتایج حاصل از شناسایی گونه‌های منطقه نشان می‌دهد 47 گونه (50%) از گونه‌های گیاهی موجود در منطقه همی‌کریپتوفیت و تعداد 59 گونه (63%) متعلق به ناحیه ایران و تورانی بودند. نتایج حاصل، نشاندهنده تاثیر خشکسالی‌های سال‌های اخیر، افزایش دما و نیز فشار چرای دام، بر گیاهان این منطقه حفاظت شده است. برای مقابله باشرایط کنونی، ضروری است که سیاست‌‌های مدیریتی و حفاظتی سازمان‌های مسئول در زمینه چرای دام، برداشت گیاهان دارویی و چوب در منطقه مورد تجدید نظر قرار گیرد.

چکیده English

The flora of a region is a key indicator of various ecosystem factors across geological periods, and plant identification is crucial for assessing natural capacity and land use. This study aimed to conduct a floristic survey of the Basiran Protected Area in Eqlid County, Fars Province. Plant samples were collected using a survey method and linear transects. From 250 collected samples, 94 species across 70 genera and 34 families were identified. Dicotyledons constituted the majority, with 82 species and 59 genera, while monocotyledons included 12 species from 11 genera. Fabaceae was the largest family (13 species), and Astragalus the largest genus (7 species). Significantly, 16 species (17%) were endemic to Iran. Phytoecological analysis revealed that 47 species (50%) were hemicryptophytes, and 59 species (63%) belonged to the Irano-Turanian phytogeographic region. The findings also highlight the adverse impacts of recent droughts, rising temperatures, and grazing pressure on the area's flora. Consequently, the study emphasizes the urgent need to reconsider current management and conservation policies, particularly concerning livestock grazing, medicinal plant harvesting, and wood collection, to ensure the long-term sustainability of this protected ecosystem.
