Based on the data of three-year water quality evaluation of a basin of the Huaihe river , ID3 decision tree algorithm was improved with the combination of user’s interest and MID3 algorithm. The improved algorithm was then employed in the water quality evaluation, and established an evaluation model, which realized water environment quality evaluation and decision support. The experimental results show that the improved algorithm of the decision tree is of high precision and simple tree structure which is more in line with the actual situation and has certain practical value in making objective and reasonable evaluation.
