校园空气质量监测与综合评价

The Monitoring and Evaluation of Air Quality in the Outdoor Environment of the Campus

以华北电力大学北京校区的空气质量状况为研究对象,采用现场监测方法,对校园空气中二氧化氮、二氧化硫、可吸入颗粒物及降尘等常规指标进行连续监测及分析,将所得到的空气监测样本数据应用模糊数学评价法进行了综合评价,结果表明:华北电力大学校区的空气质量状况具有明显的地域特征;监测期间内主要的空气污染物质为降尘,其所占当日权重全部在0.4以上。由此可见,高速公路、建筑施工工地对校园空气质量存在很大的影响,且生活区模糊综合评价结果及综合评价值要远优于临街办公区。

The air quality condition and the noise environment of the North China Electric Power University Beijing school district is chosen as the research objects,and site test was used for the monitoring and analysis of the nitrogen dioxide,sulfur dioxide,particles and falling dust in this paper. A fuzzy evaluation method is employed for the comprehensive evaluation of air monitoring samples. The result indicates that the air quality condition and the noise environment of the North China Electric Power University is obviously regional ,the main air pollution material is the falling dust during period of monitoring, and the weight of falling dust is above 0.4 each day. The result indicates that the air quality condition of highway and constructions building have a great influence on the environment quality in campus. The results of fuzzy evaluation method and comprehensive evaluation index method of living areas are superior to the ones of work region.
