摘要
为了充分发挥大型仪器设备在本科生实验教学中的作用,结合环境影响评价课程教学中有关大气环境质量评价的内容,将激光雷达观测气溶胶的变化作为环评实验课开设。通过了解激光雷达的原理和操作步骤后,要求学生根据连续24 h的观测结果计算垂直高度PM10浓度的变化,然后分析污染边界层日平均变化趋势。学生完成的实验结果显示夜间至清晨的污染边界层高度高于白天的污染边界层高度。激光雷达实验的开设既开阔了学生的眼界,又提高了大型设备的使用率。
In order to make full use of large-scale instruments in undergraduate experimental teaching, laser radar is used to measure aerosol changes in EIA experimental course after taking into consideration of the content of atmosphere environment evaluation in environmental impact assessment course. ＇After understanding the principle and the operating procedures, the students are asked to calculate the PM10 concentration at vertical height and analyze the daily average change of the pollution boundary layer according to the 24 hours continuous monitoring results. The laser radar experiment can not only broaden students＇ horizons, hut also improve the utilization rate of large-scale instruments.
