Abstract—In this work, the pollution characters of phosphorus in valley of the Yellow River with an area, capacity and mean
the two lakes are discussed. The average concentrations of TDP, depth of , ×108~3×108m3 and respectively.
DRP and DOP in the Wuliangsuhai Lake were higher than those The major sources of intake of the lake are farmland drainages
of the Daihai Lake. The DOP concentrations account for not less from Hetao Irrigation District. There are six families, six
than 60% of the total dissolved phosphorus (TDP) and the DOP genera and eleven species of macrohydrophyte recorded in the
pools in the overlying water of the two lakes are of 12t and 10t lake characterized by munis Trirn and
respectively. The contents of Al-P and ACa-P in sediments from Potamogeton pectinatus L. being the dominant species.
the Wuliangsuhai Lake are notably higher than those in the Almost half of the lake is covered by emergent vegetation,
Daihai Lake. However, the contents of Ex-P and De-P in mainly munis Trirn. In the
