| 摘 要： | 对巴东官渡汇流口网箱养殖区进行了现场调查和实验室分析，结果显示其水质变化规律为网箱养殖区劣于控制断面区域，控制断面劣于背景和削减断面，同一断面水质基本相同，控制断面水质由网箱向外逐渐变好。主成分分析表明，不同养殖区对水体污染影响依次为：中华鲟养殖区>鸭嘴鲟养殖区>黄颡鱼养殖区>鲤鱼、草鱼混养区。各水质指标相关性分析表明，官渡Chla与总磷和氨氮高度相关；氨氮、总氮、总磷和高锰酸盐指数4个指标明显相关，说明其污染源具有同源性，该水域污染主要受到网箱养殖的影响。以超河流背景断面浓度5％作为划定超背景污染带的标准，网箱养鱼引起的氨氮超背景污染面积最大，约为网箱面积的10倍，高锰酸盐指数超背景污染面积最小，约为网箱面积的5倍

| Abstract: | According to the spot investigation and the experimental analysis of fish cage-farming in the confluence of Badong Guandu,results demonstrated that the water quality of cage-farming area was inferior to the control cross section,and control cross section was inferior to the background and cross section.The water quality of different sampling stations on the same cross section was immovable basically.However,the water quality of controls in cross section was gradually improved as far from cage-farming area.A... |
