چکیده

شیردار(Acer cappadocicum Gled.) یکی از گونه‌های جنس افرا و جزء گونه‌های درختی مهم و بومی جنگل‌های شمال کشور است. هدف از انجام پژوهش پیش‌رو بررسی برخی از خصوصیات رویشگاهی و صفات کیفی درختان شیردار در جنگل‌های جنوب ساری بود. با مطالعه و بررسی جنگل‌های منطقه مورد مطالعه، بخش‌هایی که شیردار در آنجا حضور داشت، انتخاب شد و 93 قطعه‌نمونه 10 آری در شرایط فیزیوگرافیک مختلف (ارتفاع از سطح دریا، شیب و جهت جغرافیایی) به‌طور انتخابی پیاده شد. در قطعات نمونه، مشخصات جغرافیایی منطقه و صفات کمی و کیفی درختان شیردار ثبت شد. به‌منظور بررسی شرایط خاک منطقه نیز 20 نمونه خاک به‌طور تصادفی برداشت شد. نتایج نشان داد که تعداد درختان شیردار در هر قطعه‌نمونه از حداقل یک تا حداکثر 29 درخت متغیر بود. اثر فاکتورهای فیزیوگرافی شامل شیب، جهت جغرافیایی و ارتفاع از سطح دریا بر پراکنش شیردار معنی‌دار بود، به‌طوری‌که بیشترین فراوانی شیردار در شیب 21 تا 40 درصد، جهت‌ شرقی و محدوده ارتفاعی 1501 تا 1700 متر از سطح دریا مشاهده شد. کمترین درختان راستار شیردار در شیب یک تا 20 درصد، جهت شرقی و ارتفاع 1701 تا 1900 متر از سطح دریا مشاهده شد و بیشترین درختان قائم شیردار نیز در شیب 81 تا 150 درصد، جهت غربی و ارتفاع 1901 تا 2100 متر از سطح دریا دیده شد. همچنین بیشترین فراوانی درختان شیردار در خاک‌های لومی مشاهده شد، اما قطورترین و بلندترین درختان شیردار در خاک‌هایی با بافت رسی حضور داشتند.

چکیده [English]

The cappadocian maple (Acer cappadocicum Gled.) is one the important maple species and native to the northern forests of Iran. The aim of this study was to investigate some habitat characteristics and quality of A. cappadocicum in the forests of south Sari in Mazandaran province. To this aim, parts of forests with high a presence of this species were selected and 93 sample plots of 0.1 ha each were established with selective sampling method in different physiographic conditions (elevation, slope gradient and aspect). Geographical conditions of each plot as well as the quantitative and qualitative traits of maple trees were recorded. To survey soil properties, 20 soil samples were also randomly collected. The results showed that the number of maple trees varied between 1 to 29 in each sample plot. Moreover, the Physiographic factors significantly affected the distribution of maple trees, and the highest abundance was observed between 21% to 40% slopes, Eastern aspect and altitudes ranging between 1501 to 1700 meters above sea level. On the contrary, the lowest number of erect maple trees was observed on 1 to 20% slope, East aspect and between 1701 to 1900 meters altitude, whereas vertical maple trees were mostly observed in 81 to 150% slopes, western aspect as well as 1901 to 2100 m above sea level. The maple trees were mostly abundant in loamy soils, but the thickest and highest individuals occurred on clay soils.
