摘要：The post-evaluation of the impact of water conservancy projects on the ecological environment provides scientific decision-making basis for the ecological and environmental management of water conservancy projects, which has important scientific significance and application value. The post-evaluation index system of the impact of the water conservancy project on the ecological environment was constructed, and the FME-AHP evaluation model was used to evaluate the ecological environment impact of the Stone reservoir. AHP weighting method was used to determine the weight of each level, and the normal membership function was used to calculate the membership value of each level index to the next level. It can be seen from the membership degree of each grade of the ecological environment system that the maximum membership degree of the third grade is 0.4332, followed by the membership degree of the second grade, which is 0.3453. This indicates that the influence of Stone river reservoir on the ecological environment is at the third grade (no influence) and tends to the second grade (with relatively adverse influence).
