Based on the understanding of the concept of happiness river, taking 6 rivers with moderate river scale in Qiqihar Areas as an example, the TOPSIS evaluation model is constructed by combining the proportional scale AHP and AEM to carry out the evaluation on the happiness river, whose goal was divided into 5 guiding layers and 20 indicator layers. The evaluation results show that the overall happiness of the rivers in Qiqihar Areas is grade Ⅲ, which the happiness of Yalu River is grade Ⅳ, the happiness of Alen River, Nuomin River, Yin River and Runjin River is grade Ⅲ, and the happiness of Chaoer River is grade Ⅱ. In addition, the common problems of poor evaluation grade in the results were analyzed and the treatment suggestions were put forward.
