By taking removed soil fertility betterment project in the Three Gorges Reservoir area for an exam-ple, and through analyzing the engineering characters of the project, performance evaluation index system is divided into the performance and effectiveness indicator systems by the principles of science and operability. Accordingly, analytic hierarchy process is used to determine index weights. Finally, the analysis of project performance evaluation is made by fuzzy comprehensive evaluation method. The analysis shows that the com-prehensive evaluation vector for the effectiveness indicator system of the removed soil fertility betterment project is 0.8751 and for the performance indicator system, 0.6170. By the principle of the maximum mem-bership degree, the project is a quality project, no matter the effectiveness or performance evaluation.
