Abstract: Due to college students improper behavior which doesnt go with the safety code of conduct, accidents happen on the campus from time to time. Thats to say, casual behavior brings to the campus potential safety hazard. According to backward stochastic differential equation, an abstract model which interprets the random phenomenon from future to now in a reverse way, the aim to build safe campus, students conduct and the campus are integrated into an equation model. We used some existing result such as the existence solution, the comparison theorem, Levis lemma, the comparison theorem to study the problems on building safe campus and the approach to reach this goal. In the light of the reasons why students behavior deviates from the school rule, there are some suggestions specific to it.

Key words: backward stochastic differential equation, college, safe campus, institution, construct

摘要： 校园意外事故的发生往往由大学生行为不符合安全行为规范引起，随意行为给校园安全带来隐患。基于倒向随机微分方程这一由将来到现在逆向递归解释不确定随机现象的抽象模型，将构建安全校园的目标、大学生个人行为和学校三者整合到一个方程模型中，借用倒向随机微分方程解的存在性、比较定理、Levi引理、反比较定理等成熟理论，研究高校安全校园构建问题，分析大学生行为背离学校规定的原因，并提出建议。
