Abstract: In order to achieve the accuracy of ecological environment quality assessment under river safety regulation, this article conducts research on the construction method of a qualitative evaluation model for ecological environment quality. Firstly, construct an evaluation system and establish the main framework for qualitative evaluation of ecological environment quality. Secondly, the analytic hierarchy process was used to determine the criteria layer indicators, and 18 evaluation indicators were selected for the indicator layer. Thirdly, the information entropy redundancy is determined based on the entropy method, and the index weight is calculated. Finally, establish a comprehensive evaluation index, determine specific scoring standards for each indicator state, match different scoring levels based on the scores, and complete the construction of an ecological environment quality assessment model to achieve accurate evaluation of ecological environment quality. By combining the average score of each region and the average score of each indicator, it can be concluded that the final score of the ecological environment quality assessment in the study area is 70.97 points, which belongs to a good level. This indicates that the overall ecological environment quality of the region is in a good state after river safety renovation.
