以大型体育赛事风险演化为研究起点,将熵理论和耗散结构理论作为指导思想,将体育赛事风险事件发生的动因及控制措施分别作为熵增因素(diS)和负熵因素(deS),来描述体育赛事风险的演化规律。推演出大型体育赛事风险系统熵的表达式为:S=(?)KjS(jo)分析结果表明:根据大型体育赛事风险系统熵(dS)的变化,可以将赛事风险演化分为酝酿、诱发、爆发、恢复和消失五个过程;对应赛事风险演化的不同阶段提出应采取预警、反应、救援、持续干预、评估恢复的对应措施。
Taking the risk evolution of large sports events as the research starting point, entropy theory and dissipative structure theory are taken as the guiding ideology, and the causes and control measures of the risk events of sports events are respectively taken as the entropy increasing factor (dS) and negative entropy factor (deS) Describe the evolution of the risk of sports events. According to the change of the entropy (dS) of the risk system of the major sports events, the risk evolution of the events can be divided into brewing, evoking, The process of emergence, recovery and disappearance. According to the different stages of the evolution of the risk of the event, it is suggested that the corresponding measures of early warning, response, rescue, continuous intervention and assessment and restoration should be taken.
