چکیده: اکوسیستم های گیاهی کره خاکی سرویس ها و خدمات متفاوتی را ارائه می دهند، با توجه به شرایط حال حاضر کره زمین و آلودگی بیش از حد اتمسفر یکی از مهم ترین خدمات جوامع گیاهی ترسیب کربن در طولانی مدت در درون خاک می باشد. در مطالعه حاضر هدف بررسی تاثیر قرق بر میزان ترسیب کربن و خصوصیات فیزیکی و شیمیایی خاک در مراتع نیمه استپی استان چهارمحال و بختیاری می باشد. در هر منطقه(قرق و غیر قرق) هفت سایت همگن از لحاظ شرایط محیطی انتخاب و نمونه برداری از پوشش گیاهی و خاک درون آن انجام گردید. نمونه بردای پوشش گیاهی با استقرار ترانسکت و نصب پلاتهای چهار مترمربعی صورت گرفت و برداشت نمونه خاک تا عمق 30 سانتی متری در هر پلات در هر سایت نمونه برداری انجام شد. زیتوده هوایی و لاشبرگ در هر پلات جمع آوری و توزین گردید. نتایج حاصل از تجزیه و تحلیل داده ها نشان داد که میزان زیتوده هوایی، کربن خاک و کل کربن ترسیب شده در اکوسیستم در مراتع نیمه استپ گندمی به ترتیب با 99/1 t/ha، 75/51 t/ha و02/53 t/ha بصورت معنی داری بیشتر از مراتع نیمه استپ بوته زار برآورد گردید. میزان زیتوده هوایی، کربن زیتوده هوایی، درصد پوشش و کربن خاک منطقه نیمه استپ گندمی به ترتیب با 99/1 t/ha، 95/0 t/ha، 91/67% و 8/540 t/ha بیشتر از منطقه نیمه استپ بوته زار می باشد. همچنین نتایج نشان داد میانگین ترسیب کربن کل و خاک در هر دو منطقه مورد مطالعه در تیمار قرق تفاوت آماری معنی داری با تیمار غیرقرق دارد.
Abstract Earth Plant ecosystem offers different services, given the current conditions Earth and excessive pollution atmosphere, carbon sequestration to soil by plant communities is one of the most important services in long time. The present study was aimed to assess the effect of exclosure on carbon sequestration and soil physical and chemical properties in rangelands Chaharmahal and Bakhtiari Province. In each region, seven homogenous sites (grazed and non-grazed) were selected in terms of environmental conditions and vegetation and soil sampling were achieved in the each site. The vegetation sampling was done in rangeland with the establishment of transects and install a four-square-meter plots. The soil samples were done to a depth of 30 cm in each plot at the each site. Aerial biomass and litter in each plot were collected and weighed. The results of analysis data showed that the amount aerial biomass, soil carbon, and total carbon sequestration in semi-steppe rangelands with dominated grasses respectively, with 1.9 t/ha, 51.75 t/ha, and 53.02 t/ha were significantly estimated more than semi steppe shrubland rangeland. The results also showed that the average total carbon sequestration and soil in both study areas in treatment exclosure had a significant difference in grazingland treatment
