The applied principle and procedure of modified intimate data method for environmental quality assessment were discussed.The modified intimate data method was applied to the evaluation of trophic types for Shanzi Reservoir.The results were satisfied,compared with those of fuzzy membership function and grey correlation method.The standards of trophic types P_1~P_6 or P_4~P_6 were brought into the initial matrix A,and the obtained evaluation results were the same for judging(trophic) types and sorting order of Shanzi Reservoir.The evaluation method was easy and its result was practicable.It also could reflect the variety of good and bad quality of all kinds of evaluation samples.
