南通市沿海海域水环境容量计算及应用

ake the sea area along coastal Nantong object of study, the sea area water environmental capacity will be divide into coastal waters and offshore waters of water environmental capacity to calculated separately on the base of the marine area characteristics; Take the China seas tide-wave model calculation results as the hydrologic design conditions, set up 2D unsteady hydrodynamic-water quality model, and convergence with the \"marine function zoning of Jiangsu Province \", comparison of the pollution mixed area formed by terrestrial rivers and the \"marine functional zoning\" provisions of the pollution mixed area, taking the smaller as the coastal waters of water environment capacity, comparison of the pollution mixed area formed by the off-shore pollution outfall and the \"marine functional zoning\" provisions of the pollution mixed area, taking the smaller as the offshore waters of water environment capacity, then summarizes the sea area water environmental capacity, and get residual water environmental capacity of coastal Nantong according to survey of pollutants into the sea to be the status quo.
