Abstract

The seasonal variation of aero-anions for six forest community types （i.e. evergreen broad-leaved forest communities dominated with Cyclobalanopsis glauca，Schima superba，Cyclobalanopsis glauca，C. sclerophylla，Lithocarpus glaber and coniferous forest communities dominated with Pinus massoniana，Cupressus funebris，or natural forest communities dominated with Cyclobalanopsis glauca，Schima superba，Cyclobalanopsis glauca，C. sclerophylla，Lithocarpus glaber，Pinus massoniana，and artificial forest communities dominated with Cupressus funebris，Myrica rubra） was studied using synchronous monitoring of negative air ions，PM10 （particulate matter ＜ 10 m），and micro-climate factors at Laoshan Forest Farm，Qiandao Lake，Chunan County，China，during the four seasons of 2010. Analysis included a comparison of the polarity ratio and an air quality assessment index. Results showed that：（1） the concentration of aero-anions was highest in summer and second in autumn. （2） The annual average aero-anion concentration for the six forest community types was above 1 000 indcm－3. Aero-anions by communities showed natural forest ＞ artificial forest and evergreen broadleaved forest ＞ coniferous forest. （3） The air quality assessment index by season was summer ＞ autumn ＞ spring ＞ winter. （4） Natural forest air quality was at the B-level in winter，and A-level in other seasons，whereas artificial forest air quality was A-level in summer and autumn，B-level in spring，and C-level in winter. Comparing the polarity ratio and the air quality assessment index for different seasons in these forest communities，the air quality of natural forest communities was better than artificial forest communities. These results provided the theory basis for the seasonal variation characteristics of aero-anions for six forest community types.［Ch，1 fig. 4 tab. 20 ref.］
