中文摘要：

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1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／cm^3，最大值约在21：00，为986个／cm^3，最小值约在12：00，为610个cm^3；（2）浦口区年平均大气负（氧）离子浓度为675个／cm^3，其中夏季最高，为728个／cm^3；冬季最低，为538个／cm^3；（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；（41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）。

英文摘要：

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）.
