The contents of COD,TN,N03-N,TP and sulfide in the bottom mud of upstream (control),downstream and cage culture area of Three Gorges of Yangtze River reservoir were investigated from Jun. 2005 to Apr. 2006. The result indicated that,the contents of COD,TP,TN and NO3-N in downstream and cage culture area were 5.4~6.5 mg/g,0.03 ~0. 08 g/kg,40~80 mg/kg and 0. 8 ~ 1.2 mg/kg higher than control area,respectively;the average content of sulfide in the water of downstream and cage culture area was 1. 3 mg/L and 0.11 mg/L higher than control area,respectively.
