摘要
通过对南四湖水域营养盐、污染物对比发现:南四湖养殖区和非养殖区水体TN、TP、COD、Cu含量差别不大,石油类养殖区略高;养殖区TLI(∑)与非养殖区TLI(∑)差别不大。南四湖进行网箱、网围养殖,对湖区水环境无明显影响。
Comparison of the nutrients and contaminants of waters between culture area and non--cul- ture area of Nansi Lake： There is not much difference on the content of total nitrogen, total phos phorus, COD and Cu. Oil content of culture area is slightly higher; There is not much difference on TLI （∑）. Thus cage culture and pen culture had no significant effect on water quality of Nansi Lake.
