佳木斯不同生态功能区空气负离子水平研究

Study on Air Negative Ions Concentration in Different Ecological Functional Zones of Jiamusi

选择佳木斯市具有代表性的生态功能区作为研究对象,对各生态功能区的空气负离子浓度和空气质量进行比较研究。结果表明,各生态功能区空气负离子浓度差异极显著。城市绿地区空气负离子浓度日平均值均高于其他功能区,最高时可达1170个/cm3,空气质量最好;商业区和道路交通区的空气负离子浓度日平均值均较低,空气质量较差。空气负离子浓度和空气质量由大到小的排序为城市绿地区>居住区>商业区>道路交通区。

Choosing representative ecological functional zones in Jiamusi City as the objectives,the effects of different study areas on the air negative ions concentration and air quality were studied.The results showed that air negative ions concentration differed significantly with ecological functional zone.Urban greenbelt zone had the highest air negative ions concentration and the best air quality,with the maximum of 1170 ions per cubic centimeter.Commercial zone and communicant zone had lower air negative ions concentration and poor air quality.The air negative ions concentration differed significantly with ecological functional zone.The air negative ions concentration and air quality in different ecological functional zones decreased in the order of urban greenbelt zone habitation zone commercial zone communicant zone.
