使用基于栅格的地理信息系统,采用径流曲线方法和污染物流失方程,计算环罗源湾陆域氮磷污染物入海通量及其空间分布。结果表明,起步溪流域是罗源湾海域最主要的陆域污染来源,水土流失和生活污染对海域的污染输入显著。
Using grid-based GIS, runoff curve method and pollutant loss equation were used to calculate the flux and spatial distribution of nitrogen and phosphorus pollutants entering the Luoyuan Bay area into the sea. The results show that the watershed is the most important source of land-based pollution in the waters of Luoyuan Bay. The water and soil loss and pollution of life have significant impacts on the pollution of the sea.
