摘要: 空气负离子成为空气清洁度的重要评价指标。利用2009年天津城区空气负离子观测数据,研究天津城区空气负离子的时空变化规律。结果表明:天津城区空气负离子月变化浓度呈双峰型分布,主峰值出现在9月,次峰值出现在5月,7月份负离子浓度最低;四个季节中负离子的日变化特征存在明显差异;天津市和大连市两个沿海城市的负离子浓度范围相差不大,最低值均出现在7月份,但二者月变化规律趋势不同。

Abstract: Air anion becomes an important evaluation index of air cleanliness. The temporal and spatial distribution characteristics of air anion were analyzed based on the observational data in 2009 in Tianjin. The results indicate that the curve of average monthly concentration of air anion is bimodal. The highest peak value occurs in September and the second one in May, while the lowest one is in July. The daily variation of air anion in four seasons is significantly different. The ranges of air anion concentration are similar in coastal Tianjin and Dalian. Their lowest values appear in July, while their monthly variation trends are different.

Key words: Air anion, Monthly variation, Diurnal variation, Tianjin
