摘要/Abstract

摘要： 利用南京市浦口区境内老山森林、农庄、珍珠泉、石桥万诚4个观测点2014年10月~2015年10月大气负（氧）离子观测资料，分析了浦口区大气负（氧）离子浓度的时空变化特征及其与气象因子的关系。结果表明：（1）浦口区日平均大气负（氧）离子浓度为688个/cm³，最大值约在21：00，为986个/cm³，最小值约在12：00，为610个cm³；（2）浦口区年平均大气负（氧）离子浓度为675个/cm³，其中夏季最高，为728个/cm³；冬季最低，为538个/cm³；（3）浦口区大气负（氧）离子空间分布规律为：农庄> 珍珠泉> 老山森林> 石桥万诚；（4）不同天气条件下大气负离子与气象因子的相关性不同，如雨日，大气负离子与降水量、气温、相对湿度显著相关（P<0.01）；无雨天，大气负离子与日照显著相关（P<0.05）。

Abstract: Spatiotemporal characteristics of negative air ions concentrations and their relationships with meteorological factors in Pukou (Laoshan Forest, Nongzhaung, Pearl Spring, Shiqiaowancheng) were analyzed between Oct 2014 and Oct 2015. The results showed that:(1) The daily average concentration of negative air ions were 688/cm³ in Pukou (Nanjing), the maximum value of 986/cm³ appeared around 21:00; the minimum value of 610 appeared around 12:00; (2) The annual average concentration of negative air ions were 675/cm³ in Pukou (Nanjing), and the largest average concentration was 728/cm³ in summer, while the lowest was 728/cm³ in winter; (3) The negative air ions concentration was the largest in Nongzhuang, while the lowest in Shiqiaowancheng; (4) In different weather conditions, the relationships between negative air ions concentration and meteorological factors were different. In rainy, negative air ions were significantly correlated with precipitation, temperature and relative humidity (P < 0.01). In non-rainy days, negative air ions were significantly correlated with sunshine (P < 0.05).

Key words: negative air ion, concentration variation, spatial distribution, meteorological factors
