TEMPORAL CHANGES IN CARBON AND NITROGEN LEVELS IN SEDIMENT FROM PAVEDn AND UNPAVED FOREST ROADS

摘要

In this study, we determined the carbon (C) and nitrogen (N) contents along with the mass flux in sediment from a paved forest road (PFR), unpaved forest road (UPFR), and an undisturbed areas (UA) in Belgrad Forest in Istanbul, Turkey. The sediment samples were collected monthly during a one-year period from November 2009 to October 2010, and we found that the monthly sediment production rates on the UPFR was significantly higher than on the PFR and in the UA. In addition, significant temporal d
