Vulnerability assessment of agricultural flood and mitigation countermeasures in Fujian Province
福建省农业水灾脆弱性评价及减灾对策

Based on natural disaster system theory ,the paper established an index system and modeled flood system vulnerability assessment, including agricultural flood hazard, disaster formative environment, hazard-affecting body and disaster mitigation level. With the aid of digital map technology,the paper used data from the hazard and soeio-eeonomie databases of Fujian Province,compiled vulnerability distribution and average frequency of agriculture flood in the province. Results show that, flood vulnerability obviously differs from east to west in Fujian. Regions with maximum value are concentrated in the eastern coastal area, with the exception of Fuzhou, Xiamen and Quanzhou ;consistent with the eastward sloping topography, agricultural hazard-affecting body distribution, and distribution of average flood frequency in the past 35 years. Based on the established formative mechanism of agricultural flood and accompanying sustainable development patterns, the paper suggests enhancement in regional flood risk research, adjustment in land-use and farming structures under ecological security, increases in input in flood prevention projects in coastal regions, clearing of river-ways at fixed intervals, to reduce agricultural flood vulnerability. This can benefit agricultural flood prevention and disaster reduction.
