【 摘 要 】

Risk assessment of drought and flood sudden turn is very important for flood control and drought relief in summer. Based on the mechanism of drought and flood disaster risk, a risk model of drought and flood sudden turn in the Pearl River Basin is constructed. Results show that the risk values of drought and flood sudden turn in the Pearl River Delta and the North-South Panjiang River are large and fluctuate with time. The risks of Drought-flood abrupt alternation (DFAA) in the eastern and western parts are relatively higher than that in the central part, which indicates that the distribution of DFAA in the Pearl River basin is affected by large-scale weather system and local topography.
