本文根据灾害风险分析原理，建立了一个经三层逐级放大的农业气象灾害风险分析实用模型，并以珠江三角洲荔枝生产为例分析计算了主要农业气象灾害以及风险体系的风险度，其结果对农业气象灾害风险管理与决策及灾害防御有一定的参考价值
Based on the principle of disaster risk analysis, this paper establishes a three-layer operational model of agricultural meteorological disaster risk analysis amplified step by step. Taking the production of litchi in the Pearl River Delta as an example, the risk of major agricultural meteorological disasters and risk systems are calculated and analyzed. Agricultural meteorological disaster risk management and decision-making and disaster prevention have some reference value
