      [摘要] 目的 了解我县中小学校教室的光环境现状、特点和规律,为制订合理的学校光环镜设计方案,实现教学环境最优化和保护学生视力提供科学依据。 方法 对我县 152 间中小学校,按县、镇、乡三级区域进行分层抽样,共抽取 183 间课室进行光环境检测。 结果 我县小学教室的平均面积为 49.65m2,每班的平均人数为 31.89 人;中学教室的平均面积为 60.98m2 ,每班的平均人数为 49.81 人。不同级别小学之间,人均面积(乡级 93.6%,镇级 77.8%,县级 22.2%)及黑板长达标率(乡级 31.9%,镇级 61.1%,乡级 77.8%),差异有统计学意义(P < 0.05)。县级人均面积低于乡级和镇级小学(P < 0.001);乡级小学黑板长度达标率低于镇级,县级小学黑板长度达标率高于镇级(P=0.004);不同级别中学之间,人均面积(镇级 55.8%,县级 20%)及黑板下缘到讲台垂直高度达标率(镇级 44.2%,县级 80%)差异有统计学意义(P < 0.05)。县级人均面积低于镇级中学(P=0.038);县级黑板下缘到讲台垂直高度达标率高于镇级(P=0.038)。 结论 县级中小学人均面积合格率均低,乡级和镇级小学黑板长度达标率低,县级中学黑板下缘到讲台垂直高度达标率高,我县中小学自然采光、人工照明及黑板设置状况较好。
英文摘要:
      [Abstract] Objective To understand the current situation, characteristics and rules of the light environment in the classrooms of primary and secondary schools in our county and to provide scientific basis for formulating a reasonable design scheme of the light environment in schools,realizing the optimization of the teaching environment and protecting students’ eyesight. Methods The 152 primary and secondary schools in our county were stratified sampled according to three levels of counties,towns and townships,and a total of 183 classrooms were selected for light environment detection. Results The average area of primary school classrooms in our county was 49.65m2 and the average number of students in each class is 31.89.The average area of middle school classrooms was 60.98m2 and the average number of students in each class was 49.81.There were statistically significant differences in per capita area(township level 93.6%,townlevel 77.8%,county level 22.2%)and standard-reaching rate of blackboard length(township level 31.9%,town level 61.1%,county level 77.8%)among primary schools of different levels.The per capita area of county-level primary schools was lower than that of township and town-level primary schools(P < 0.001).The standard-reaching rate of blackboard length of township-level primary schools was lower than that of town-level primary schools.The standard-reaching rate of blackboard length of county-level primary schools was higher than that of town-level primary schools(P=0.004).There were statistically significant differences in the per capita area(townlevel 55.8%,county level 20%)and the standard-reaching rate of vertical height from the edge of the blackboard to the platform(town level 44.2%,county level 80%)among middle schools of different levels.The per capita area of countylevel middle schools was lower than that of town-level middle schools(P=0.038).The standard-reaching rate of vertical height from the edge of the blackboard to the platform of county-level middle schools was lower than that of townlevel middle schools(P=0.038). Conclusion The standard-reaching rate of per capita area of county-level primary and secondary schools is relatively low.The standard-reaching rate of blackboard length of township-level and townlevel primary schools is low.The standard-reaching rate of vertical height from the edge of the blackboard to the platform of county-level middle schools is high.Natural lighting,artificial lighting and blackboard settings in primary and secondary schools in our county are in good condition.
