چکیده مقاله :
The main objective of this study was to investigate the effect of forest road construction on the Soil Organic Carbon Stock (SOCS) in Ziarat Catchment. Therefore, soil samples were collected from five land use types including road construction, cultivated area, channel bank, pasture and forest land and soil organic carbon concentration and bulk density were measured in the samples and SOCS were calculated. The results showed that the forest road construction reduce SOCS. SOC stock was greatest in the forest land use and the total SOC stock under different land uses varied in order forest, pasture, cultivate, channel bank and road construction with 143, 136, 128, 36 and 29 Mgha−1, respectively (p<0.001). Therefore, these results can be useful as a scientific basis for selecting the proper soil erosion control methods as a simple and low-cost approach to mitigate the SOC loss.
هدف از این مطالعه، بررسی تاثیر جاده سازی در میزان ذخیره کربن در حوزه آبخیز زیارت میباشد. بر این اساس از 5 کاربری جنگل، مرتع، کشاورزی، جاده و آبراهه نمونه برداری و میزان کربن آلی هر کدام محاسبه شد. نتایج نشان میدهد جاده سازی عامل کاهش ذخیره کربن آلی بوده و میزان آن تفاوت زیادی در کاربری جنکل و سایر کاربریها دارد. میزان ذخیره کربن آلی در کابریهای جنگل، مرتع، کشاورزی، آبراهه و جاده به ترتیب 143، 136، 128، 36 و 29 مگاگرم در هکتار میباشد. نتایج این مطالعه میتواند در ترسیب کربن و کاهش گازهای گلخانه‌ای مفید باشد.
