چکیده

پوشش‌­های گیاهی مختلف اثرات متفاوتی بر لاشبرگ و خاک اکوسیستم­‌ها دارند. پژوهش پیش‌رو با هدف بررسی تأثیر درختان توسکای ییلاقی (Alnus subcordata C. A. Mey.)، بلندمازو (Quercus castaneifolia C. A. Mey.) و زربین (Cupressus sempervirens L. var. horizontalis (Mill.) Gord.) بر مشخصه­‌های لاشبرگ، خاک و تصاعد دی‌اکسید کربن در محدوده طرح جنگل‌داری نیرنگ- خانیکان نوشهر انجام شد. نمونه­‌برداری از لایه آلی (لاشبرگ) و معدنی (صفر تا 15 سانتی­متری) خاک به‌صورت منظم- تصادفی انجام شد. مشخصه­‌های کیفی لاشبرگ (کربن و نیتروژن)، جرم مخصوص ظاهری، بافت، رطوبت، اسیدیته، کربن آلی، نیتروژن کل و تصاعد دی‌اکسید کربن (در دما و رطوبت­‌های مختلف) در آزمایشگاه اندازه­‌گیری شد. نتایج نشان داد که بیشترین مقدار مشخصه­‌های نیتروژن لاشبرگ، سیلت و اسیدیته خاک به توسکای ییلاقی اختصاص داشت، در حالی‌که بیشترین مقدار مشخصه­‌های نسبت کربن به نیتروژن لاشبرگ، رطوبت، کربن آلی، نسبت کربن به نیتروژن خاک و تصاعد دی‌اکسید کربن در بخش زیرین توده زربین مشاهده شد. مقدار بیشتر درصد شن نیز به توده بلندمازو تعلق داشت. در تمام درختان مورد مطالعه، بیشترین مقدار تصاعد دی‌اکسید کربن در شرایط رطوبت عرصه مشاهده شد و با افزایش دما مقدار تصاعد افزایش یافت. نتایج این پژوهش بر این امر دلالت داشت که جنگل­کاری با گونه سوزنی­‌برگ زربین در سطوح وسیع می‌تواند منجر به افزایش مقدار تصاعد دی‌اکسید کربن از خاک شود که باید از دیدگاه گرمایش جهانی، در مدیریت اکوسیستم‌ها مورد توجه قرار گیرد.

چکیده [English]

Different plant covers have various effects on ecosystem litter and soil characters. This research aims to study the effect of different forest covers (Alnus subcordata C. A. Mey., Quercus castaneifolia C. A. Mey. and Cupressus sempervirens L. var. horizontalis (Mill.) Gord.) on litter, soil and CO2 emission characters in the forest management plan of Nowshahr Neirang-Khanikan. Soil samples were taken from the organic (litter) and mineral (0-15cm) layers using randomly systematic method. Litter quality characters (carbon and nitrogen), soil bulk density, texture, water content, pH, organic carbon, total nitrogen and CO2 emission (in different water content and temperature regimes) were measured in the laboratory. Results showed that the highest values of litter nitrogen, silt, pH were found in alder plantation, whereas greater amounts of C/N of litter, water content, organic carbon, C/N of soil and CO2 emission were found under cypress stand. The highest amount of sand was detected under oak stand. The maximum of CO2 emission were occurred in field capacity moisture regime and higher temperature in whole of studied plantations. The results of this research indicate that afforestation with needle-leaved species, Cupressus sempervirens var. horizontalis, can be effective on the increasing CO2 emission from soil that must be considered in ecosystem management from the global warming point of view.
