چکیده مقاله :

گونه شن (Lonicera nummularifolia Jaub. & Spach) یکی از گونه‌های با ارزش درختی و درختچه‌ای می‌باشد که در جنگل‌های زاگرس به عنوان گونه همراه با بلوط مشاهده می‌شود. با توجه به ارزش بالای این گونه از نظر حفاظتی، حمایتی و دارویی انجام مطالعاتی جامع در خصوص آن ضروری بنظر می‌رسد. لذا تحقیق حاضر با هدف بررسی موقعیت مکانی، آمیختگی و ابعاد گونه شن نسبت به درختان همسایه خود در جنگل‌های سامان عرفی پرک واقع در خرم آباد لرستان انجام شد. بدین منظور ضمن پیاده نمودن پنج قطعه نمونه یک هکتاری، درختان شن موجود شناسایی و آزیموت و فاصله تا چهار درخت همسایه اندازه‌گیری و همچنین نوع گونه و ابعاد تاج درختان همسایه بررسی شد. در این تحقیق، به‌منظور بررسی ویژگی تنوع موقعیت مکانی از شاخص زاویه یکنواخت، به منظور بررسی آمیختگی از شاخص آمیختگی مینگلینگ و به منظور بررسی ابعاد گونه شن از شاخص ابعاد تاج پوشش استفاده شد. بر اساس نتایج حاصل از این تحقیق، میانگین سه شاخص زاویه یکنواخت، آمیختگی مینگلینگ و ابعاد تاج پوشش به ترتیب برابر با 575/0، 940/0 و 590/0 بدست آمد که نشان دهنده‌ی چیدمان تصادفی این گونه نسبت به درختان همسایه، آمیختگی زیاد و ابعاد متوسط آن نسبت به سایر همسایه‌ها می‌باشد. همچنین بر اساس شاخص فاصله تا نزدیکترین همسایه، میانگین فاصله تا چهار درخت همسایه برابر با 99/1 متر محاسبه گردید. نتایج حاصل از این نوع مطالعات می‌تواند به منظور اراِئه الگویی جهت حفظ، احیا و توسعه جنگل‌های زاگرس که دارای اکوسیستم‌هایی حساس و شکننده می‌باشند، مورد استفاده قرار گیرد.

چکیده انگلیسی:

Lonicera nummularifolia Jaub. & Spach is one of the valuable trees and shrubs species that can be observed with oak species in Zagros forests. Regard to the high value of this species from protection, support and medicinal aspect, it can be necessary to perform comprehensive study. Therefore, this study was carried out in order to investigate the location, mixture and size of Lonicera nummulariifolia Jaub. & Spach in Zagros to neighboring trees in Parak Area, Khorramabad City. For this purpose, four-hectare plots was performed, L. nummulariifolia trees were identified and the azimuth and distance from four neighboring tree species and crown dimensions of neighbors trees were investigated. In this study, uniform angle index, Mingling mixture index and canopy size index were used to evaluate the diversity of positioning, to determine the mixture and to verify the dimensions of Lonicera, respectively. Based on the results of this study, an average of three uniform angle index, mingling mixture and canopy dimensions were 0.575, 0.940 and 0.590, respectively, which represent a random arrangement of this species to neighbors trees, the large mixture and medium dimensions in compared to other neighbors. Also, based on the distance index to the nearest neighbor, the average distance to the four neighboring tree was calculated equal to 1.99 meters. The results of this study can be used to provide a model to the preservation, restoration and development of Zagros forests which has fragile ecosystems.
