Application of multi level fuzzy comprehensive evaluation method in water resources assessment

Water resources issue is a big problem faced by the mankind. It is of great significance to make a correct evaluation and prediction of water resources carrying capacity in a country or region. However, lots of problems exist in the evaluation of water resources carrying capacity, such as too many evaluation indicators, difficulty in quantifying and the impact of subjective factors, etc. This paper proposes a hierarchical fuzzy comprehensive evaluation method based on analytic hierarchy process to measure the water resources carrying capacity of a region. In this paper, this model is applied to the evaluation of water resources carrying capacity of Beijing and Hubei province. Theoretical analysis and practical application show that the model is effective.
