摘要

[目的

]

对准格尔盆地南缘不同生态功能区夏季空气负离子浓度进行监测和分析

为不同地区空气质量评价提供参考依据。[方法

]

分别就不同生态功能区(水体、林区、停车场、聚集区)进行空气负离子浓度监测及评价

通过AIC-1000型空气离子测量仪进行数据采集并运用SPSS 17.0软件进行统计分析。[结果

]

(1) 不同区域生态功能区空气负离子浓度变化由高到低依次为:精河>天池>哈密>巴尔鲁克

且精河、天池与哈密、巴尔鲁克之间差异显著(p

0.05); (2) 不同生态功能区中水体和林区空气负离子浓度含量较高

且空气负离子浓度随时间的变化出现早、晚较高

中午较低的动态变化趋势; (3) 空气质量等级指标:天池(A级

1.28±0.42 ind/cm

) > 精河(A级

1.16±0.08 ind/cm

) > 哈密(D级

0.33±0.14 ind/cm

) > 巴尔鲁克(D级

0.32±0.03 ind/cm

); (4) 不同天气状况对空气负离子浓度影响较大

主要表现为:雨天(699 ind/cm

) > 沙尘(507 ind/cm

) > 晴天(428 ind/cm

) > 阴天(395 ind/cm

)。[结论

]

不同生态功能区空气质量变化与空气负离子浓度变化基本一致

空气质量沿准格尔盆地南缘由东到西呈现劣-优-劣的分布规律。

Abstract

[Objective] Air anion concentration in different ecological functional zones in southern margin of Junggar Basin was monitored in summer in order to provide a reference for rating regional air quality. [Methods] The concentrations of negative air ion in different ecological function areas (water body

forest area

parking lot

populated districts)by AIC-1000 type instrument. SPSS 17.0 was used for statistical analysis. [Results] (1) The concentrations in different regional areas ranked as: Jinghe > Hami > Tianchi > Baerluke. And the difference between the concentrations of Jinghe and Tianchi and values of Hami and Baerluke was significant (p<0.05); (2) In local ecological function areas

water body and forest area had higher concentration of negative air ions; and the daily concentration showed that it was higher in the morning and evening

and lower in the noon; (3) The rank of air quality levels(CI): Tianchi (level A

1.28±0.42 ind/cm3) > Jinghe (level A

1.16±0.08 ind/cm3) > Hami (level D

0.33±0.14 ind/cm3) > Baerluke (level D

0.32±0.03 ind/cm3); (4) Weather conditions could also influence the concentration of negative air ions

a rank was measured as: rainy(699 ind/cm3) > dust(507 ind/cm3) > sunny(428 ind/cm3) > cloudy(395 ind/cm3). [Conclusion] Changes in air quality and the concentration of negative air ions were basically synchronized in different ecological function areas. Air quality along the southern Junggar Basin showed an inferior-superior-inferior trend graphically form east to west.
