基于心理承压的灾害可承受风险评估

Risk Assessment of Disaster Bearability Based on Psychological Pressure

评估灾区人群的灾害可承受风险时,可以先从灾区患病人群挖掘、心理风险源因素识别两方面进行分析,通过基于信息熵的灾后患有心理疾病人群挖掘算法,挖掘灾区患有心理疾病人群,减少评估范围;面向挖掘出的心理疾病患者采用改进ISR压力模型,判断心理风险源因素,提高评估结果准确性;最后通过建立的灾害可承受风险评价指标体系,构建基于心理承压的灾害可承受风险评估模型,评估灾区中患有心理疾病人群的灾害风险承受能力。为验证基于心理承压的灾害可承受风险评估模型有效性和性能优势,进行实验验证。结果表明,该模型可有效评估灾区人群基于心理承压的灾害可承受风险,评估复杂度低于5%。

When assessing the disaster risk of people in disaster-stricken areas, we can first analyze the excavation of the affected population and the identification of the source factors of psychological risk. Through the algorithm of excavation of people with mental illness after a disaster based on information entropy, we can excavate the people with mental illness in the disaster-stricken areas. Reducing the scope of the assessment;Improved ISR stress model is used to determine the source factors of psychological risk and improve the accuracy of evaluation results. Finally, a risk assessment model based on psychological stress was constructed to evaluate the disaster risk tolerance of people with mental illness in the disaster area. In order to validate the effectiveness and performance advantages of the risk assessment model based on psychological stress, experiments were carried out. The results show that the model can effectively assess the risk of disaster withstandability of disaster-stricken population based on psychological pressure, and the evaluation complexity is less than 5%.
