ملخص المقالة :
زمینه و هدف: از وقایع مهم در زندگی جنگل، زادآوری درختان جنگلی است که تداوم حیات و پایداری دایمی یک جنگل از درختان مختلف، به آن‌ها بستگی دارد. بنابراین شناخت عوامل مؤثر بر روند استقرار گونه های جنگلی می تواند ما را در شناخت بهتر مراحل مختلف توالی این اکوسیستم یاری کند. هدف این مقاله بررسی تأثیر توسعه جنگل بر زادآوری گونه های چوبی درختی و درختچه ای در منطقه ذیلکی رودبار است.روش بررسی: برای انجام این تحقیق، قسمتی از جاده جنگلی سری 4 ذیلکی رود با سن 18 سال که به لحاظ ارتفاع، جهت دامنه، تغییرات شیب و ترکیب گونه ای دارای وضعیت یکنواختی بود، با طول کافی (500 متر) انتخاب و در جاده ۶ ترانسکت، به‌طور یک‌درمیان به سمت بالا و پایین دامنه و به طول ۵۰ متر و عمود بر آن با استفاده از طناب و قطب نما پیاده گردید. در هر ترانسکت در فواصل ۱، ۵، ۱۰، ۳۰ و ۵۰ متر، پلات‌های موازی با جاده و به ابعاد ۲ متر در ۱۰ متر پیاده شد و در داخل هر قطعه نمونه، نوع و تعداد زادآوری گونه های چوبی درختی و درختچه ای برداشت شد.یافته‌ها: بر طبق نتایج، تفاوت آماری معناداری بین میانگین تعداد زادآوری گونه ها در پایین دست (9/13± 8/28) و بالا دست جاده (9/12±4 /32) وجود نداشت. آنالیز واریانس نشان داد که میانگین تعداد زادآوری بین فواصل مختلف در پایین دست و بالا دست جاده دارای اختلاف معنی داری می باشد. در پایین دست جاده، به احتمال 95 درصد، میانگین تعداد زادآوری در فاصله 5 و 1 متر از جاده به ترتیب دارای بیش‌ترین (0/7± 0/39) و کم‌ترین مقدار (4/10± 0/16) می باشد.بحث و نتیجه‌گیری: برای بقاء هر نوع پوشش گیاهی، امکان زادآوری اهمیت ویژه ای دارد و از آنجا که جاده ها، مسیرهای دست‌یابی به اکوسیستم های جنگلی، هم برای انسان و هم برای گونه های گیاهی و جانوری مهاجم محسوب می شود، آﮔﺎﻫﻲ از ﺷﺮاﻳﻂ پوشش گیاهی و خاک ﻣﻨﻄﻘﻪ ﺗﺤﺖ ﻣﺪﻳﺮﻳﺖ و بررسی ﻣﺴﻴﺮﻫﺎی ﺟﺎده ﺟﻨﮕﻠﻲ به منظور به ﺣﺪاﻗﻞ رﺳﺎﻧﺪن ﺧﺴﺎرات وارده ﺑﻪ زادآوری ضروری ﻣﻲﺑﺎﺷﺪ.
