Abstract
In this paper,the estimation methods of GIS,the experimental coefficient of sewage disposal and estimation model were mainly used to estimate the marine pollutants loads in West Sea and Tong'an Bay in Xiamen,including the pollution sources from the land-base,atmospheric deposition and aquaculture,and the annual pollutant fluxes of CODMn,TN,TP in every sea area.The estimation results of pollution fluxes and marine pollution loads of main pollutants(CODMn,TN,TP) in every sea areas were given.The result showed that the land-based pollution holds were the largest percentage of marine loads in every sea area,over 75.2%.The pollution source from the atmospheric deposition was the second proportion of 1.2%~18.4%.The pollutant from the aquaculture was the smallest proportion,less than 1%.
