In recent years, the number of ships in inland rivers has been on the rise, and the problem of inland river pollution has attracted widespread attention from all sectors of society. As a branch of the inland river and the largest reservoir and power station in Northeast China, the prevention and control of pollution in Shuifeng Reservoir is particularly important. To evaluate the potential risk of fishing boat pollution in Shuifeng Reservoir, this article innovatively uses a combination calculation method of Analytic Hierarchy Process and Entropy Weight Method; At the same time, in the process of setting risk assessment indicators for Shuifeng Reservoir, a comprehensive evaluation index system is constructed based on the actual situation, and various levels of indicators are calculated. The final results show that for the current overall pollution situation of Shuifeng Reservoir, there are mainly problems such as a small amount of supervision and insufficient awareness among residents, and corresponding measures have been taken. This study can provide reference for the future environmental development of Shuifeng Reservoir.［Chinese Fishery Quality and Standards,2024,14(2):35-42］
