Abstract:
Diurnal and annual variation of air negative ions at four different sites(Kunlun Bridge，Water Park，Yangliuqing Manor and field)in Tianjin were studied,influence of air humidity and temperature were analyzed.The results showed that diurnal variation of air negative ions firstly increased and then decreased，and the maximum value mostly occurred at noon which was slightly different in various sites；annual variation of air negative ions presented summer>spring>autumn，and maximum occurred in July；the variation tendency of air negative ions was completely similar to that of humiture in different sites，presenting positive correlation；air quality in Water Park was the best of all，and that of field was the worst.Forests could provide air negative ions，consequently purifying the air pollution，which was in favor of human bodies.Therefore，urban landscaping should be enhanced in the city construction.
