Abstract: In view of the limitation that the weight setting of the VFM qualitative evaluation is difficult to highlight the influence of factor layers and the fuzzyness and uncertainty of evaluation result, according to the characteristics of the urban water ecological PPP project in China, the index system of VFM qualitative evaluation for urban water ecological PPP project was constructed. The qualitative evaluation method of urban water ecological PPP project based on OWA-gray clustering was proposed, using OWA operator to weight the indexes, and VFM gray clustering evaluation model was used to do the evaluation. According to the practical study result of a sewage treatment project in Hubei Province, the evaluation method was proved to be effective. The results can provide reference for VFM qualitative evaluation of urban water ecological PPP project.
