高校突发事件学生心理危机预警指标体系主要来自于专家经验，主观性强、冗余度大，且通过该指标体系搜集到的信息系统是一个不完备的偏序系统。文章提出了一种基于限制优势关系粗糙集的指标约简方法，将限制优势关系引入目标信息系统的部分一致协调约简，构建限制优势关系下的部分一致函数和部分一致辨识矩阵，实现预警指标的约简，获取学生心理危机的引致要素；最后，结合算例进一步说明该方法的有效性。

The common early warning index system of university student psychological crisis which is constructed based on the expert experience has strong subjectivity and big redundancy .The informa-tion system based on such index system is an incomplete ordered system .For this problem ,a method of index reduction based on limited dominance relation rough sets is proposed .By introducing the lim-ited dominance relation into partial consistency reduction of the target information system ,the partial consistency function and partial consistency discernable matrix are built to reduce the early warning in-dexes and to obtain the key indexes which lead to student psychological crisis .An example demon-strates the validity of this method .
