Research on cumulative environmental impact assessment on integrated marine engineering of Bohai Bay

Certain environmental factor's change leads to the imbalance of marine environmental system. The engineering cumulative impact wasn't considered within the environmental impact assessment, so the environmental impact results are not completely. In this paper, an integrated cumulative impact analysis and assessment of hydrodynamic and water environment by the great marine engineering of Hebei and Tianjin in the Bohai Bay is implemented. The assessment results show that the cumulative impact of great marine engineering is not ignored.
