ABSTRACT

This paper uses a multi-level fuzzy comprehensive evaluation model to establish the Saihanba ecological environment (wind-defense and sand-fixing) evaluation scoring system based on a fuzzy comprehensive evaluation model. In terms of determining the weight, the weights given in the authoritative national standard documents are tapped to ensure the objectivity of the results. In terms of data comparison results, 24 items are selected, which deepens the vertical dimension of the data to ensure the accuracy of the results. Combining the above two key factors, establish a corresponding multi-level fuzzy comprehensive evaluation scoring system. The evaluation is concluded that during the 30 years before and after the restoration of Saihanba, the ecological quality has improved. The environmental quality has increased by 37% year-on-year.
