| Abstract: | It's important that we should select suitable water quality indicators and assess its status in quo before taking an effective measure. This paper introduces correlation analysis method into the selecting of indicators firstly, and then uses gray correlation method to assess the water quality of Bohai Bay. The result has shown that the water quality from 1995 to 1999 was polluted seriously, but since 1999, the water quality has improved evidently. |
