福建三都澳水产养殖区水体氮磷含量及潜在性富营养化程度分析

Nutrient salts content and eutrophication assessment for Sanduao sea area, Fujian

根据 2 0 0 1年 1～ 1 2月对福建三都澳内青山和渔坛两个主要网箱养殖区海水营养盐 (NH3 N、NO3 N、NO2 N和PO4 P)含量的监测结果 ,报道了其含量变化特征及潜在性富营养化程度 .结果表明 :该水体NO3 N、NO2 N、NH3 N、PO4 P的平均含量分别为 0 .3 0 6、0 .0 1 7、0 .0 2 4、0 .0 3 4mg dm3 .这两个养殖区水体的潜在性富营养化程度春、夏季属于中度营养 ,秋、冬季属于富营养 .

Based on the survey data of the nutrient salts content in Sanduao sea area from Jan.2001 to Dec. 2001, the water quality and eutrophication level of the aquaculture area. The con- tents of NO 3-N,NO 2-N,NH 3-N,PO 4-P are 0.306, 0.017, 0.024, 0.034mg/dm 3. The results shown: this area is at eutrophication level in autumn and winter, and it is at middle eutrophication in spring and summer.
