Screening of Rapid Vegetation Restoration Models in Earthquake-stricken Areas Based on Grey Relation Analysis

Based on the damage degrees of earthquake-stricken areas, 11 vegetation restoration models were selected for severely damaged sites and 6 vegetation restoration models for moderately damaged sites. The restoration effects of each model were compared by the grey relation analysis method. According to the results, the rapid vegetation restoration model with high survival rate, soil organic matter content, biomass and high coverage was screened. The screening process and results of the experiment are of great reference values for the rapid vegetation restoration in earthquake-stricken areas.
