ملخص المقالة :
زمینه و هدف: اخیراً در تحلیل های مرتبط با الگوی مکانی درختان، روش های نوینی توسعه یافته اند که به منظور بررسی، به یک نقشه کامل از موقعیت مکانی درختان نیاز دارند. به کارگیری این روش ها به مقیاس مطالعه بستگی دارد به نحوی که تغییر مقیاس مطالعه می تواند سبب تغییراتی در الگوی مکانی درختان شود. پژوهش حاضر با هدف تعیین مناسب ترین سطح قطعهنمونه جهت کمیسازی الگوی مکانی درختان ارس دامنه جنوبی البرز صورت پذیرفت. روش بررسی: بدین منظور قطعهنمونه ای به مساحت شش هکتار انتخاب و الگوی مکانی درختان با استفاده از تابع g(r) مورد بررسی قرار گرفت. سپس سطح این قطعهنمونه به پنج، چهار، سه، دو و یک هکتار کاهش و الگوی مکانی درختان با استفاده از تابع g(r) بررسی و نسبت به سطح مبنای شش هکتاری مقایسه شد. یافته ها: نتایج حاصل از این تابع نشاندهنده ی الگوی مکانی یکنواخت در فواصل بین درختی تا چهار متر، الگوی کپه ای در فواصل شش تا ده متر و الگوی تصادفی در سایر فواصل می باشد. نتایج حاصل از مقایسه نمودارهای تابع g(r) در مساحتهای مختلف نشان داد که روند کلی تابع g(r) تا سطح سه هکتار تقریباً ثابت و در سطوح کوچک تر، تغییر می کند، بنابراین حداقل سطح مناسب در این بررسی، سه هکتار به دست آمد. بحث و نتیجه گیری: تعیین مناسبترین سطح قطعه نمونه در مطالعات ساختاری ضمن افزایش دقت مطالعات می تواند سبب کاهش زمان و هزینه مطالعه گردد.
