Research on Land-Use Type of Huainan City Based on Flood Risk Perception and Spatial Multi-Criteria Analysis

Abstract

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 base on the experts' quantitative analysis. The results contain many indexes that can not be accurately quantified. This paper presents a pragmatic approach for balancing quantified data and non-quantified data in land planning for risk areas. Theoretical framework of the approach incorporates quantitative analysis method, classification analysis approach for risk perception of the public, and spatial multi-criteria analysis structure system. 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. In this paper, risk perception will be used as an important reference index of multi-criteria analysis to analyze the correlation between risks and benefits. Consequently, more effective land use planning would be provided with the index of risk perception of the public taken into consideration.
