摘 要:目的了解2016—2020年北京市中小学教学环境卫生状况变化趋势,为改善中小学校教学环境提供依据。方法采用按比例系统抽样,2016—2019年每年在北京市抽取50%以上学校,2020年抽取34%学校。抽中学校根据结构等选取有代表性的2间教室进行检测,共对6196间教室的卫生学指标进行监测,其中2016—2020年各年分别监测1330,1312,1384,1322,848间教室。结果2016—2020年教室总体采光合格率(采光系数72.8%,窗地面积比41.8%,后侧墙反射比42.2%,黑板反射比37.4%),黑板平均照度、均匀度合格率(50.6%,34.9%)和课桌椅分配合格率(58.6%)均低于80%,教室人均面积(87.5%)、黑板尺寸(83.2%)、课桌面平均照度(80.1%)、课桌面照度均匀度(82.9%)、灯桌间距(99.1%)、二氧化碳(86.6%)、温度(84.9%)、噪声(96.6%)指标总体合格率均高于80%。黑板尺寸、灯桌间距、黑板平均照度、采光系数、黑板反射比、后侧墙反射比、二氧化碳、温度、噪声指标年份间差异均有统计学意义(χ^(2)值分别为78.38,9.71,11.76,320.59,37.63,58.45,236.45,1347.56,101.97),其中黑板尺寸、黑板反射比、采光系数、噪声指标合格率逐年升高(χ_(趋势)~2值分别为69.98,15.82,240.02,5.77)(P值均<0.05)。小学教室人均面积、窗地面积比、黑板反射比指标合格率(81.6%,39.8%,36.3%)均低于中学(94.9%,44.5%,40.3%)(χ^(2)值分别为246.32,12.03,10.51),黑板尺寸、黑板平均照度、黑板照度均匀度、课桌椅配置指标合格率(89.3%,55.6%,36.0%,60.2%)均高于中学(75.4%,44.1%,33.3%,56.5%)(χ^(2)值分别为209.33,78.41,4.44,8.22)(P值均<0.05)。城区课桌面平均照度和均匀度、黑板平均照度、后侧墙反射比、课桌椅配置、二氧化碳、温度、噪声指标城区合格率(82.9%,84.1%,51.9%,45.0%,60.9%,91.2%,89.5%,97.8%)均高于郊区(77.3%,81.7%,49.2%,39.5%,56.3%,82.3%,80.4%,95.5%)(χ^(2)值分别为31.16,6.28,4.36,16.40,13.39,105.29,98.23,24.66),灯桌间距、采光系数、窗Objective To understand the trend of changes of hygiene status in the teaching environment among primary and secondary schools in Beijing City during 2016-2020,so as to provide basis for further improving the teaching environment and campus hygiene conditions in primary and secondary schools.Methods A proportional systematic sampling method covered over 50%of schools selected annually in Beijing from 2016 to 2019,and 34%were selected in 2020.Two representative classrooms were selected from each selected school for testing based on their structure and other factors,with 6196 classrooms supervised,from 2016 to 2020,1330,1312,1384,1322,848 classrooms were monitored for each year.Results From 2016 to 2020,the overall lighting qualification rate of classrooms(lighting coefficient 72.8%,window to floor area ratio 41.8%,rear wall reflectance ratio 42.2%,blackboard reflection ratio 37.4%),the overall qualification rate of average blackboard illumination and uniformity(50.6%,34.9%),and the overall qualification rate of desk and chair allocation(58.6%)were all below 80%.The overall qualification rate of per capita classroom area(87.5%),blackboard size(83.2%),average desk illumination(80.1%),average desk illumination and uniformity(82.9%),the distance between lamp and desk(99.1%),carbon dioxide(86.6%),temperature(84.9%),and noise(96.6%)were all above 80%.The following indicators,blackboard size,the distance between lamp and desk,average blackboard illumination,lighting coefficient,blackboard reflectance,rear wall reflectance,carbon dioxide,temperature,and noise(χ^(2)=78.38,9.71,11.76,320.59,37.63,58.45,236.45,1347.56,101.97),had statistically significance between years.Among those indicators,the qualified rates of blackboard size,blackboard reflectance,lighting coefficient,and noise had been increasing year by year(χ^(2)trend=69.98,15.82,240.02,5.77)(P<0.05).The qualified rates of per capita classroom area,window to floor area ratio,and blackboard reflection ratio in primary schools(81.6%,39.8%,36.3%)were all lower than t
