| 英文摘要 | Internal phosphorus (P) loading is regarded as a major eutrophication factor and may prevent improvements in lake water quality. Two new in situ passive sampling techniques, high-resolution pore-water equilibrators (HR-Peeper) and zirconium oxide-based diffusive gradients in thin films (Zr-oxide DGT), were combined to measure dissolved reactive phosphorus (DRP) (C-Peeper) and labile phosphorus (C-DGT) at five sites in South Dongting and West Dongting Lakes. The vertical distribution of C-Peeper and C-DGT displayed similarity, which demonstrated that the buffering capacity of the labile P in sediments was similar at different depths. The diffusion flux of P from the sediments at the sediment-water interface ranged from 1.9 to 88 ng m(-2) day(-1), with an average value of 38 ng m(-2) day(-1). The P flux at the entrances to the Yuan, Li and Zi Rivers was fairly large at all five sites. The sediments at the five sites released P into overlying water, indicating that the sediments are an important source of P for Dongting Lake. |
