Assessment of capacity of flood disaster prevention and reduction of Huaihe River Basin in Anhui Province
安徽淮河流域洪涝灾害防灾减灾能力评估

Taking the Huaihe River Basin in Anhui Province as the study area and following principles of objectivity, data availability, feasibility of index quantification and highlighting dominant factors, the index system of assessment of capacity of flood disaster prevention and reduction was established at city-county level, which is composed of capacity of flood prevention and waterlogging control, capacity of flood monitoring and warning, capacity of rescue and rehabilitation, and capacity of disaster management. The judge matrixes of index system and index weights were established by the Analytic Hierarchy Process (AHP) approach based on opinions from experts. Then a capacity map of flood disaster prevention and reduction of the Huaihe River Basin in Anhui Province was generated. The result shows that the capacity of flood disaster prevention and reduction is the highest in Bengbu city, followed by Huainan city, Huaibei city, Fengtai county, Fuyang city, Chuzhou city, Suixi county and Suzhou city, while the others have relatively low and even lower capacity of flood disaster prevention and reduction. A further analysis shows that the capacity is low in regions to the south of the mainstream of the Huaihe River compared with northern Huaihe River plain and the same is to the result of right-hand regions of Shaying River compared with the left-hand regions. The capacity is relatively low in Guoyang county and Bozhou city among the regions along the Guohe river. The index system and assessment method helps provide references for assessment of capacity of flood disaster prevention and reduction in other basins or regions, and may provide a basis for the work of flood prevention and reduction in China.
