The evaluation of effects of geological disaster control projects is an important stage in regional disaster prevention and reduction. It can be used to test quality, mechanisms and plan selections of the projects, provide reference for the subsequent similar disaster control projects in the region as well. In view of features of geological disaster control projects, three first-level indicators standardization of project construction, effectiveness of disaster prevention and reduction, and benefits of project, have been sorted out for formation of comprehensive evaluation index system of geological disaster control projects, with 10 secondary indicators including reasonableness of project design, construction under design, engineering construction quality, maintenance of project in operation, aims achieved under design, capacity of geologic disaster elimination, effects of disaster prevention in long term, social benefit, economic returns, environmental protection integrated. With various index weight determined by Analytic Hierarchy Process（APH）, quantitative indicators for evaluation method of effects of geological disaster control projects are from multi-factor weighted index of the projects. Take control project on a landslide in Tianshui Industrial Vocational and Technical College, for example, we can find that multi-factor weighted index for evaluation on control effects is feasible and correct.
