The security of stadium is one of the problems increasingly concerned by people. Among various security problems, the fire risk of stadium is the most important. By using principal component analysis (PCA) and combining the influencing factors of risk prediction of stadium, several influencing factors of the fire risk of stadium are evaluated and analysed, then the uppermost principal component factors are selected, the inconspicuous components are eliminated, the influence of relevant factors on the fire risk prediction of stadium is analysed, and the correlation of various indicators with fire risks of stadium is understood to find the potential best security management prediction system, for the purpose of taking pertinent prediction measures of fire accident risks to overcome the unfavourable factors in the security management, and ensure the safe and normal operation of stadium as well as the personal and property security of sporters.
