Comprehensive evaluation method of flood risk based on multi-level gray system model——a case study in Poyang Lake Basin
Flood risk assessment is a systematic process with the synergy effects between multiple factors.Based on the analysis of flood risk system,a comprehensive flood risk assessment system was constructed in consideration of the factors including the disaster-inducing factors,disaster-inducing environment,and disaster bearing body from the perspective of flood risk evaluation.The data processing advantages of gray clustering method and analytical hierarchy process(AHP) were integrated and a comprehensive evaluation method of multi-level gray system was proposed to adapt the flood disaster risk prediction.The method was applied in the Poyang Lake Basin.The combination of qualitative and quantitative analysis of the flood risk system in the Poyang Lake Basin can provide reference for the comprehensive evaluation of flood risk in the basin.
