2009年深圳市宝安区部分中小学校教学环境卫生状况调查

Investigation on Environmental Health Status of Primary and Secondary Schools' Teaching Environment in Baoan District,Shenzhen City,2009

[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1920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。

[Objective]To understand the environmental health status of primary and secondary schools＂ teaching environment in Baoan distriet,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-car）ira area was 71.88% ;the standard-reaching rate of orienta- tion 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 desks 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,espeeially environmental noise and improper deskchair setting.
