The result shows that: aquicultural waste water discharge respectively account for 75.1% of total nitrogen and 63.5% of total phosphorus; subsequently, the second main source of nitrogen and phosphorus is Domestic Sewage and Industrial Sewage drainage, which respectively equals to 20.5% and 30.7% of total nitrogen and phosphorus; in addition, farmland is not the main source, and only contributes to 4.4% of total nitrogen and 5.8% of total phosphorus.

结果表明，盐城海岸带主要陆源污染源中，养殖水域氮磷排放总量为7641t和480t，分别占排放总量的75.1%、635%；其次为居民工矿的生活生产污水，其氮磷排放量为2083t和232t，占总排放量的20.5%、30.7%；农田目前看来不是盐城海岸带主要的陆源污染源，排放量仅占4.4%和5.8%。

In the coastal zone of Yangcheng, terrestrial pollutions include the farmland run off, aquicultural waste water discharge, domestic sewage and industrial sewage drainage.
