| چکیده | ||
| آشفتگی‌های طبیعی و انسانی منجر به کاهش تنوع بیولوژیکی و درنتیجه کاهش پایداری اکوسیستم‌ها شده‌اند، بنابراین متریک‌هایی که اطلاعات کیفی بیشتری در مورد تک‌تک گونه‌ها و ترکیب کلی جوامع گیاهی فراهم کنند، می‌توانند برای ارزیابی محیط‌های طبیعی، ارزش‌های حفاظتی آنها و اثرات آشفتگی‌های انسانی، مفید واقع شوند. در پژوهش پیش‌رو برای اولین بار در ایران، در جنگل کاکارضا استان لرستان، ضریب محافظه‌کاری (Conservatism coefficient) گونه‌های گیاهی با استفاده از قطعات نمونه اصلاح‌شده ویتاکر تعیین شد. این ضریب با توجه به میزان حساسیت گونه‌های گیاهی در برابر آشفتگی‌ها و همچنین برمبنای میزان تعلقه و پایبندی گونه‌های گیاهی به شرایط اکولوژیک با استفاده از نظرات متخصصان گیاه‌شناسی تعیین شد. براساس نتایج مشخص شد که 57/67 درصد گونه‌ها در طبقه اول ضریب محافظه‌کاری (CC:1-3)، 32/17 درصد در طبقه دوم (CC:4-6)، 8/46 درصد در طبقه سوم (CC:6-8) و 1/58 درصد در طبقه چهارم (CC:9-10) قرار داشتند. همچنین گونه‌های Astragalus leonardii ،Astragalus longirostratus وBunium luristanicum در طبقه چهارم قرار گرفتند و بیشترین ضریب محافظه‌کاری را داشتند. بر این اساس و با توجه به اطلاعات موجود در زمینه موقعیت حفاظتی این سه گونه، می‌توان آنها را به‌عنوان گونه‌های معرف جنگل‌های کمتر تخریب‌یافته بلوط زاگرس معرفی کرد. استفاده از ضریب محافظه‌کاری در مناطق جنگلی کمتر دست‌خورده و مقایسه آن با مناطق دیگر، با بررسی ارزش حفاظتی مناطق مختلف و تعیین گونه‌های با ارزش حفاظتی بیشتر، منجر به ارزیابی بهتر برنامه‌های مدیریتی و احیایی خواهد شد. | ||

| چکیده [English] | ||
| Natural and anthropogenic disturbances result to loss of biodiversity and ecosystem stability decline. Metrics that aggregate more qualitative information on individual species and overall community composition could be useful to better assess factors such as the conditions of natural areas, their conservation value and the impact of human disturbance. This is the first study that determine conservatism coefficient for vascular plants in Lorestan province. The standard modified multi-scale Whittaker plots were used for vegetation sampling. A panel of botanists and ecologists were asked to assign conservatism coefficient to each native species based on their knowledge and previous experiences about plant species sensitivity to disturbances and fidelity to a specific habitat by using floristic list. Results showed that conservatism coefficient were accepted by botanists and ecologists and can be used in the next researches for identifying forests conservative values. Based on the results of 57.67 % of plants were ranked fell into the first category (1-3), while 32.27 % fell into second category (4-6), approximately 8.46% of plants were ranked into third category (7-8) and finally 1.58 % of plants were ranked in the forth category (9-10). Astragalus leonardii Maassoumi, A. longirostratus Pau. and Bunium luristanicum Rech. f. have the most values of conservatism coefficient were ranked fell into the forth category. Based on the results and with regard to species conservation status, these species can be introduced as an indicator of intact oak forest. Determining CC in the natural intact regions and comparing it with other regions is useful for evaluation of restoration programs succession. | ||
