SPATIAL AND TEMPORAL VARIABILITY OF CO_2 FLUX FROM A PEATLAND SOUTH OF VENICE

摘要

A series of CO_2 flux measurement campaigns have been performed from 2002 to 2004 by the use of the non-steady-state chamber method to assess the spatial and temporal variability of peat oxidation in a drained cultivated peatland south of Venice and to detect the relationship between the CO_2 emissions and the controlling hydrological parameters, i.e., soil temperature and moisture content. Because of the limited number of experiments available up to this date, it has been possible to obtain only a few indications on the relations between the measured quantities. The analysis of these preliminary results is presented and discussed.
