主要利用采用GIS、经验排污系数法和经验模型法,对厦门湾的西海域和同安湾两个海域的陆源、海上水产养殖和大气输入源的入海污染负荷进行估算,得出这两个海域的CODMn、总氮(TN)和总磷(TP)年入海污染通量和入海污染负荷。估算结果显示,厦门湾的入海污染负荷主要来自于陆源污染源,所占比例在75.2%以上,大气沉降污染源次之,所占的比例平均为1.2%～18.4%,而海上水产养殖带来的污染负荷所占的比例最小,平均不超过1%。
The main pollutant loading into the sea from land source, sea aquaculture and atmospheric input sources in the two seas of Xiamen Bay and Tong’an Bay is estimated by using GIS, empirical sewage coefficient method and empirical model method. The results show that CODMn, total nitrogen (TN) and total phosphorus (TP) year into the sea pollution flux and into the sea pollution load. The estimation results show that the pollution load of Xiamen Bay originates mainly from terrestrial sources, accounting for more than 75.2%, followed by the sources of atmospheric deposition, accounting for an average of 1.2% ~ 18.4%, while the pollution caused by marine aquaculture The proportion of the smallest load, with an average of not more than 1%.
