摘　　要：利用统计学及其主成分分析法对水文与水文地质考试成绩及其5种题型进行评价,结果表明,考试的总体成绩较好;各题型的均分结果显示,名词解释和填空题的得分率较高;而综合题、选择题和简答题相对较低。主成分分析的二维排序图表明,简答题和综合题得分率与第1轴关联度最高,是影响学生成绩的主要因素;另一方面,填空题和选择题与第2轴关联度较高,是次要因素。With statistics and its principal component analysis （PCA）, the evaluation of examination scores of hydrology and hydrogeology course and its five question types shows that the overall results are good. The average results of each question type show the scores for explanation of noun and blank filling are higher, while the scores for comprehensive questions, multiple choice and short answer questions are relatively low. Two-dimensional diagram of PCA shows that short answer questions and comprehensive questions are highly related to first shaft, which are the main factors influencing students＇ performances; on the other hand, blank filling and multiple choice are highly related to second shaft, which are of secondary causes.
