基于突变模型的我国食品安全风险评估

为评估我国食品安全风险,基于突变模型和结构稳定性理论,从食品产业链视角设计食品安全风险评估指标,分别测度食品的生产环节、流通环节和消费环节的风险度,得出我国近年来食品安全的总风险度,并找出我国食品的薄弱环节。结果表明:生产环节的风险度呈下降趋势,流通环节和消费环节的风险度波动较大,消费环节的风险度整体呈上升趋势,因此,流通环节和消费环节是我国食品安全需要加强的环节;近年来我国食品安全总风险值整体呈下降趋势,但仍有短暂波动,食品安全问题仍需重视。

Risk Assessment of Food Safety in China Based on Catastrophe Model

In order to evaluate China's food safety risk,on the basis of catastrophe theory and structure stability theory,the food safety risk assessment indexes were designed from the food chain perspective,the risk degrees existing in productive link,circulative link and consumptive link were estimated respectively.Thus,the total risk degree of China's food safety in recent years was obtained,and the deficiencies for food safety were identified.The results show that the risk degree existing in productive link takes...
