玉溪市中心城区TSP源解析研究

AN ANALYSIS OF FIVE CHIEF POLLUTION SOURCES OF TSP IN DOWNTOWN AMBIENT AIR OF YUXI THROUGH FACTOR ANALYSIS

用多元统计方法中的因子分析法鉴别了玉溪市中心城区TSP的5种主要污染源,并估算了这5种污染源的贡献率分别为水泥/石灰石源占52.32％、土壤源占22.74％、道路交通源占12.06％、钢铁源占7.45％、燃煤及垃圾燃烧源占3.51％。

The present paper has introduced the author's investigation and identification of the five chief emission sources of TSP (the total suspended particles) in the ambient air of Yuxi city's downtown areas. The investigation and statistics have been made by using the factor analysis method, one of Multivariate Statistical Methods. The statistical results indicate that the average contribution rates of the five chief sources that contribute to the TSP of Yuxi can be roughly estimated below: cement/limestone source was 52. 32%, soil source was 22. 74% , traffic source: 12. 06%, steel production; 7. 45% i coal and refuse combustion source was 3.51%.
