摘要
2005年6月至2006年4月对长江三峡库区投饵网箱养殖区上游、网箱养殖区以及网箱养殖区下游底泥中有机物耗氧量、TN、NO3-N、TP、硫化物等指标进行了监测。结果显示,网箱养殖区及网箱下游底泥有机物耗氧量和总磷含量分别高出对照区5.4～6.5 mg/g和0.03～0.08 g/kg,网箱养殖区及网箱下游底泥总氮含量及硝态氮含量分别高出对照区40～80 mg/kg和0.8～1.2 mg/kg,网箱养殖区及网箱下游底层水的硫化物含量平均值分别高出对照区1.3 mg/L和0.11 mg/L。
The contents of COD, TN, NO3-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.
