چکیده به منظور بررسی میزان انطباق اجرای شیوه تکگزینی از دیدگاه علم جنگلشناسی با برنامه بهینهسازی پایش، حفظ، بهره برداری و مدیریت جنگلهای کشور(مصوبه27/9/92 هیئت وزیران)، نشانهگذاری قطعه 17 طرح جنگلداری سری 1 رشته رود واقع در حوزه 19 رودبار مورد مطالعه قرار گرفت. ارزیابی فنی بوسیله شبکه سلولی خاص (که هر سلول نمایانگر سطح تاج یک درخت به قطر هدف رسیده است) انجام گرفت. معنیدار بودن اختلاف سلولهای دخالت شده از کل سلولهای قابل دخالت، به کمک آزمون دوجملهای تست شد. نتایج نشان داد که طرح بهداشتی دیکته شده دولت، بدلیل پراکندگی نامنظم درختان ناسالم، کل سطح جنگل را پوشش نمیدهد. بهنظر میرسد که نشانهگذاری انجام شده حدود 10 درصد اهداف جنگلشناسی را در توده محقق نموده است و حدود 90 درصد سطح توده، عملا از دخالت علمی مغفول مانده است. توزیع کم و نامتناسب دخالتهای پرورش جنگل باعث میشود که فضای رقابت رویش قطری برای اکثریت درختان جوان فراهم نگردد. نتیجه دیگر بدست آمده از این پژوهش، ابداع روش کاربردی برای ارزیابی عملکرد نشانه گذاری و دخالت جنگلشناسی است. بدین ترتیب به کمک شبکه سلولی10×10 متر مربعی و با ثبت مختصات درختان نشانه گذاری شده در روی شبکه، امکان ارزیابی میزان دخالت مکانی طی دورههای دهساله فراهم می گردد. واژه های کلیدی: نشانهگذاری، پایش، توده، شبکه سلولی، رشتهرود منبع:مجموعه مقالات همایش ملی جنگلهای شمال-گذشته حال آینده- دانشگاه گیلان1396نوع مطلب : مقالات علمی، برچسب ها : نشانه گذاری، پایش، جنگل، طرح، لینک های مرتبط : سه شنبه 29 آبان 1397 07:58 ب.ظ
