Abstract: According to the rainwater utilization theory and having analyzed the makeup of rainwater utilization system, this paper has established a index system for evaluating the environmental benefit of rainwater utilization from ecology and economy and society aspects, has also detailed the systems constituting program, method, principle, structure and the contents. Besides, the calculation methods of the pertinent indexes were presented. The dominant factor of the assessment is different on different scales. Based on this trait and analytic hierarchy process theory, this paper has proposed the evaluating process of environmental benefit from rainwater utilization.

Key words: rainwater utilization system, environmental benefit, index system, calculation method
