【摘要】 [目的]了解深圳市宝安区中小学校教学环境的卫生状况,发现问题,提出改进措施。[方法]2009年5~10月,分两阶段在宝安区32所中小学,抽取有代表性的教室进行调查,并抽取部分学生测量身高与课桌椅高度。[结果]在32所中小学调查192间教室,测量黑板174块,教室人均面积达标率为71.88%,朝向达标率为78.13%,采光系数达标率为93.23%,玻地比达标率为96.35%,采光方向达标率为96.35%,后墙反射系数达标率为4.17%,桌面照度达标率为98.96%,噪声强度全部超标;黑板课桌距离达标率为42.19%,黑板尺寸达标率为70.69%,黑板反射系数达标率为89.08%;测量学生1 920名,课桌椅配置符合率为10.31%。综合评价得分,18所私立学校为69.49分,14所公立学校为74.87分。[结论]深圳市宝安区中小学教学环境质量存在较多问题,环境噪声和课桌椅配置不符合问题最为突出。更多还原

【Abstract】 [Objective]To understand the environmental health status of primary and secondary schools’ teaching environment in Baoan district,Shenzhen,find out problems and figure out the ways to solve.[Methods]In May-October 2009,32 primary and secondary schools were investigated by two phases.In each school,representative classrooms were drawn and investigated,and also the height of some students and desks and chairs.[Results]In 32 schools,192 classrooms,174 blackboards were tested.The standard-reaching rate of per-capita area was 71.88%;the standard-reaching rate of orientation was 78.13%;the standard-reaching rate of lighting coefficient is 93.23%;the standard-reaching rate of glazing to floor area ratio 96.35%;the standard-reaching rate of lighting orientation was 96.35%;the standard-reaching rate of back wall reflection coefficient 4.17%;the standard-reaching rate of desktop illumination was 98.96%;all of the noise intensity reached standard;the standard-reaching rate of blackboard and desk’s distance was 42.19%;the standard-reaching rate of blackboard size was 70.69%;the standard-reaching rate of blackboard reflection coefficient was 89.08%;1 920 students’ height was tested,and the coincidence rate of desk-chair setting was 10.31%.The comprehensive evaluation rate of 18 private schools was 69.49,while the rate of 14 public schools was 74.87.[Conclusion]There are many environmental quality problems in primary and secondary schools of Baoan district,Shenzhen,especially environmental noise and improper desk-chair setting.更多还原
