Evaluation Indexes and Methods for Water Quality in Ocean Dumping Areas

In this paper, the commonly used method and current used index system for comprehensive evaluation of water quality of ocean dumping areas are analyzed. We found that the normal methods such as single factor method and comprehensive index method are more and more unqualified to deal with the nonlinear, non-normal distribution, and high dimensional of the data, while the indexes should be added because new toxic pollutants brought to dumping areas as the rapid grows of ocean dumping activities is also rapidly increasing. Finally, a system of evaluation indexes and methods for comprehensive evaluation of water quality of ocean dumping areas is constructed.
