摘要
从2017年8月至2018年7月,对湖南省森林植物园内空气负氧离子浓度、温度、降雨量、相对湿度等指标进行测定,分析空气负氧离子浓度特征及导致其浓度差异的影响因素。结果表明:空气负氧离子浓度季节变化特征为夏季>秋季>春季>冬季;空气负氧离子浓度变化情况与温度变化情况基本一致;春季、秋季、冬季空气负氧离子浓度的日变化规律大体一致,且冬季的日变幅最小,夏季日变幅最大;空气负氧离子浓度与温度、降雨量、相对湿度基本呈正相关,降雨量对其存在显著差异(P <0. 05),温度对其存在极显著差异(P<0. 001),相对湿度对其无显著差异。
During August 2017 to July 2018,the NAI(negative air ion)concentrations,temperature,rainfall and relative humidity were measured in Hunan Forest Botanical Garden.The variation characteristics of NAI concentrations were analyzed,and the factors leading to differences in NAI concentrations were discussed.The results showed that the seasonal variation trend of the NAI concentrations was:summer>autumn>spring>winter.The monthly changing trend of NAI concentration was basically identical with the temperature.The variation trend of the daily NAI concentrations showed consistency with rainfall in spring,autumn and winter,and the smallest diurnal variation was in winter,the greatest diurnal variation was in summer.The NAI concentrations were basically positive correlated with the temperature rainfall,and relative humidity.It displayed a significant correlation between NAI concentrations and rainfall at 0.05 level,and a highly significant correlation between NAI concentrations and temperature at 0.001 level,but no significant correlation between NAI concentrations and relatively humidity.
