| 摘 要：利用连续一年旌德县负氧离子监测数据，分别以兔儿山公园、路西村茶园代表城市公园、高山茶园这两种生态环境，对城市公园和高山茶园负氧离子浓度特征以及气象要素对负氧离子浓度影响进行比较分析。结果表明：①高山茶园负氧离子浓度显著高于城市公园；②负氧离子浓度夏季最高，冬季最低，春秋季次之，6月负氧离子浓度达全年最高；③负氧离子浓度日变化整体呈“一峰一谷”变化趋势，峰值出现在上午，谷值出现在正午前后，夜间至上午负氧离子浓度较高，城市公园负氧离子浓度日较差较高山茶园偏小；④负氧离子浓度日变化与气温、风速呈显著负相关；⑤负氧离子浓度雨天最高，晴天次之，阴天和多云相对较低，暴雨天气条件下大气负氧离子浓度显著提高。 |

| Abstract: This paper used data for one year from the observation of Negative Oxygen Ions (NOIs) in Jingde county, Tuershan Park and Luxi Village Tea Garden were chosen as two different ecological environments of Urban Park, Alpine Tea Garden, compared and analyzed the characteristics of NOIs concentrations between Urban Park and Alpine Tea Garden and the correlation with meteorological factors. The results showed that: ①The concentrations of NOIs were significantly higher in Alpine Tea Garden than those in Urban Park. ②The concentrations of NOIs were the highest in Summer, the lowest in Winter, followed by Spring and Autumn, and reached the highest in June. ③The daily variation of NOIs concentrations in these two regions showed a trend of “single peak and single valley”, with the peak value appeared in the morning and the valley value appeared in the noon, the concentrations of NOIs were higher from night to morning, and the daily range of NOIs concentrations in Urban Park were smaller than that in Alpine Tea Garden. ④the daily variation of concentrations of NOIs were significantly negatively correlated with air temperature and wind speed. ⑤The concentrations of NOIs were highest in rainy day, followed by sunny day, and lower in overcast day and cloudy day, the concentration of NOIs increased significantly under rainstorm conditions. |
