摘要：

Concentrations of dissolved (DOC) and particulate organic carbon (POC) in two billabong wetlands (Murrumbidgil Swamp and Lake Merrimajeel) in inland temperate Australia were positively correlated with leaf fall from river red gums Eucalyptus camaldulensis (DOC and POC in Murrumbidgil Swamp), phytoplankton productivity (DOC in Murrumbidgil Swamp, DOC and POC in Lake Merrimajeel), and with biomass of aquatic macrophytes (DOC in the two wetlands). DOC correlated with water level at both sites. Mean concentrations of DOC (Murrumbidgil Swamp, 36.0 g m-3; Lake Merrinmajeel, 27.5 g m-3) and POC (15.0 g m-3; 15.5 g m-3) were high compared with other water bodies worldwide, although average for wetlands. The relatively high concentrations of DOC and POC in the study wetlands appear to be the result of their high rates of plant production, and input of leaves from river red gums.
