摘要
碳的氧化物、硫的氧化物、氮的氧化物和卤化物等是由人类的生产活动和社会活动产生的重要的环境污染物质 .它造成了温室效应、酸雨、对流层的光化学雾和平流层的臭氧耗减等环境问题 .它威胁着人类的生存环境和地球上的生态平衡 .光谱技术可广泛应用于环境污染监测 .文章简要介绍全球面临的主要环境问题 ,重点介绍光谱技术 (包括常规光谱技术、激光光谱技术以及激光雷达等 )在大气环境监测中的应用和进展 .利用这些技术 ,可以获得污染物的组分、浓度、温度或空间分布等方面的信息 .
Oxides of carbon, sulfur, nitrogen and halogens are serious environmental pollutants produced by the productive and social activities of humans. Global environmental problems, such as the green house effect, acid rain, photochemical smog in the troposhpere and ozone depletion in the stratosphere are created by these environmental pollutants. They serivously threaten our life and the ecological balance of the Earth. Spectral techniques can be widely used in the monitoring and detection of environmental pollution. A brief introduction to global environmental problems is presented, with details on the application of traditional spectral, laser spectral and laser radar techniques to the monitoring of atmospheric environmental pollution. Information concerning the composition concentration, temperature and spactial distribution of environmental pollutants can be obtained by these techniques.
