本文报告应用瑞文测验（ＣＲＴ一ＲＣ）中国农村版和城市智商常模对济南市区学龄儿童的智商进行了测试，结果表明：济南市儿童智商基本呈正常分布，略向高值偏移。儿童的智商除受碘元素影响外，也与学生的生活营养水平和父母的文化程度有关，且不同年龄、性别和不同测试时间儿童的智商水平无显著性差异（Ｐ＞０．０５），但智商与学生的学习成绩明显相关（Ｐ＜０．０１），智商与数学的相关系数大于与语文的相关系数，说明ＣＲＴ一ＲＣ是测验学生抽象思维能力的有效工具。碘缺乏是目前已知的导致人类智力障碍的主要原因，济南市区为轻度缺碘地区，应该采取全市居民食用碘盐的措施来防治碘缺乏的危害。
This paper reports a test of IQ of the school-age children in Jinan using CRT-RC rural version of China and urban IQ norm. The results show that the IQ of children in Ji’nan is basically normal, with a slight shift toward higher values. In addition to the influence of iodine, children’s IQ is also related to the nutritional level of their students and the educational level of their parents. There is no significant difference in IQ among children of different ages, genders and test times (P> 0.05) IQ was significantly correlated with students ’academic performance (P <0.01). The correlation coefficient between IQ and mathematics was greater than that between Chinese and English, indicating that CRT-RC is an effective tool to test students’ abilities to abstract thinking. Iodine deficiency is the leading cause of human mental retardation, Jinan City is mild iodine deficiency areas, the city’s residents should take measures to eat iodized salt to prevent the harm of iodine deficiency.
