Research on Land Use Type Based on Flood Risk Perception and Spatial Multi-Criteria

In traditional risk analysis approaches,emphasis is put on quantitative analysis of accident probability and consequences but no effective multiple analysis results are obtained with risk perception of the public taken into consideration.Usually,analysis results used by the governmental organizations for land planning in risk areas are the results based on the experts' quantitative analysis.The results contain many indexes that can not be accurately quantified,such as development of nature,bio-diversity,and attitude of the public towards risks that can not be incorporated into quantitative calculation system,leading to the existence of problems in planning of whole risk areas.This paper presents a pragmatic approach for balancing quantified data and non-quantified data in land planning for risk areas.This approach is eventually used for case analysis in the planning for land along the banks of the Huai River in Huainan city in the middle reaches of the Huai River in Anhui Province,China.This approach integrates risk perception of the public and its application on the basis of spatial multi-criteria analysis.
