Abstract Taking the project of "Enclosing Mountain for Green" that was carried out in the Hanquangou valley of Gansu province as study object and based on the multi-objective decision-making model, the authors of this paper developed a integrated evaluation indices system on the project performance through approaches of rural household survey, consulting experts, statistical report analysis, and in situ experiment. By the use of the evaluation system the authors synthetically evaluated the effect on ecological rehabilitation of the "Enclosing Mountain for Green" project in Hanquangou valley. It was concluded that the ecological effect is remarkable, producing economic value as 5.217×106 Yuan per year. Especially, the effects on ecosystem stability and soil conservation ability are outstanding. The score given for the comprehensive effect is 77.0, reaching relatively good level.
