| 摘要: |
| 在不同季节对深圳坝光银叶树（Heritiera littoralis）湿地园内不同地点的空气颗粒物浓度 （TSP、PM10、PM2.5 及 PM1.0）进行了 8:00、10:00、12:00、14:00 及 16:00 时共 5 个时间点的观测。结果表 明，空气颗粒物浓度在不同监测区域、季节和时间均存在显著差异（P<0.001）。深圳坝光银叶树湿地园 TSP、PM10 和 PM2.5 年均值低于II 级标准浓度限值，TSP 和 PM10 日均值低于II 级标准浓度限值，PM2.5 日均值低于I 级标准浓度限值。在空间上表现为古银叶树群落区域的空气颗粒物浓度最高，海边区域最 低；在季节上，较高浓度的TSP、PM10、PM2.5 出现在夏秋季，较高浓度的PM1.0 则出现在秋冬季；在时 间上表现为正午的空气颗粒物浓度最低。 |

| Abstract: |
| In order to understand the air pollution condition in Heritiera littoralis wetland park in Shenzhen, Guangdong, we monitored the air particle matters, including TSP, PM10, PM2.5 and PM1.0, in three sites within the park at 8:00、10:00、12:00、14:00 and 16:00 for three days in different seasons. The results showed that, there were signi?cant differences in concentrations of air particle matters among sites, periods and seasons (P<0.001). The annual average concentrations of TSP, PM10 and PM2.5 were lower than the limiting value of level II of the national standard, and the daily average concentrations of TSP and PM10 were lower than the level I of the national standard. Among three observation sites, the highest particle concentrations were observed in H. littoralis community, and the lowest were in seaside area. Among four seasons, relatively high concentrations of TSP, PM10 and PM2.5 were observed in summer and autumn, relatively high concentration of PM1.0 were in autumn and winter. During daytime, the highest concentration of particles occurred at noon. |
