| 应用综合污染指数法和富营养化指数法评价了2010年度江苏近岸海域水质状况。结果表明，50%的海水水质测点已显现出不同程度的富营养化迹象；影响江苏近岸海域的首要污染物为无机氮和活性磷酸盐，二者污染分担率之和近50%；现阶段造成江苏近岸海域水体富营养化的主要因素来源于入海河流和直排海污染源的氮磷输入，与“十五”末相比，全省主要入海河流TN排放量增长约284%，TP排放量增长约451%。 |

| The research was carried for present environmental situation investigation in Jiangsu coastal area by using methods of Comprehensive Pollution Index and Eutrophication Index. The results showed that different levels of eutrophication were found on 50% monitoring sites. Inorganic nitrogen and activated phosphate were the main pollutants in sea waters of Jiangsu and contributed nearly 50% pollution. At present eutrophication was caused by land river contained nitrogen and phosphorus substances. The TN discharge increased to 284%, TP 451% from large rives into the sea in Jiangsu province, which pollutants had grown remarkably than that had done at end of “the tenth five years planning”. |
