Three warning types,poor or worse state warning,slow deterioration warning and rapiddeterioration warning have been selected for comprehensive environmental quality assessmentaccompanied with weighted average model. The warning results of TEDA's sub and wholeenvironment are got by the assessing grades. The analysis for the warning results showedthat TEDA's whole environment,air,noise environment qualities are good,but COD., in water environment appears warning. It shows that organic pollutants are the main pollutants ofwater envirommet and enough attention should be paid to this serious water pollution.
