چکیده

در این پژوهش، ساختار توده­های جنگلی زاگرس بر اساس شاخص­های مبتنی بر نزدیک­ترین همسایه در دو قطعه­نمونه یک هکتاری (حفاظت نشده) در مناطق چهارزبر و برزه بررسی و تحلیل شد. نتایج شاخص کلارک و اوانز با مقدار 87/0 و 88/0 به­ترتیب برای چهارزبر و برزه و زاویه یکنواخت به­همین ترتیب با مقدار51/0 و 5/0 نشان داد الگوی پراکنش مکانی در هر دو منطقه کپه­ای و الگوی پراکنش گونه­ای در چهارزبر تصادفی و در منطقه برزه یکنواخت است. نتایج میانگین شاخص آمیختگی با مقادیر 13/0 و 005/0 نشان داد که منطقه برزه از آمیختگی گونه­ای بسیار پایین­تری از چهارزبر برخوردار است. همچنین میانگین شاخص­های تمایز قطری با مقادیر 55/0 و 38/0 و تمایز ارتفاعی با 2/0 و 19/0 به­ترتیب برای چهارزبر و برزه محاسبه شد که نشان­دهنده تمایز ارتفاعی اندک و برتری قطری پایه­های چهارزبر نسبت به برزه است. در مجموع ساختار جنگل در مناطق مورد بررسی به­شدت دست­خوش تغییر شده است.

چکیده [English]

In this study, the structure of Zagros forest stands was analyzed using neighborhood-based indices such as Clark and Evans, uniform angle, mingling, diversity of dimensions, diversity of combined structure, and distance to the nearest neighbor in two one-hectare (unprotected) sample plots in Chaharzebar and Barzeh forest areas (as a sample of the majority of Kermanshah province's forests). Clark and Evans index values of 0.87 and 0.88 for quadrupeds and ridges, respectively, and uniform angles of 0.51 and 0.5, respectively, revealed a spatial distribution pattern in both hilly areas and a species distribution pattern in random quadrants and the Barzeh region. The average mingling index values of 0.13 and 0.005 revealed that the Barzeh region had substantially lower species mixing than the Chaharzebar region. In addition, the mean diameters of differentiation indices with values of 0.55 and 0.38, and height differentiation with values of 0.2 and 0.19, were determined for Chaharzebar and Barzeh, respectively, indicating a minor height difference and the diametric superiority of Chaharzebar trees over Barzeh. In general, the structure of the forest in the analyzed regions has been significantly altered, and the findings of the hybrid diversity index revealed a low level of biological, species, and dimensional variety in the two studied forest stands.
