Evaluation of ecological restoration effect of rare plant Rhododendron chrysanthum population in Changbai Mountain Area

Abstract In order to study the population viability and restoration effect of Rhododendron chrysanthum population after restoration, an ecological evaluation method based on analytic hierarchy process and fuzzy comprehensive evaluation was proposed. The ecological evaluation index system was established with the help of analytic hierarchy process (AHP) and the index weight was determined. The fuzzy comprehensive evaluation method was used to evaluate the restoration effect of Rhododendron chrysanthum population from three aspects: target layer, criterion layer and index layer. The results showed that this method could effectively evaluate the ecological effect of Rhododendron chrysanthum population after restoration, in which 33% of the restoration effect of Rhododendron chrysanthum population might be “very good” and 67% might be “good”. According to the principle of maximum membership degree, the comprehensive evaluation of the restoration effect of Rhododendron chrysanthum population in the experimental area was excellent.
