- 摘要:
- 以北京市4种常见树木国槐（Sophora japonica）、栾树（Koelreuteria paniculata）、旱柳（Salix babylonica）、刺槐（Robinia pseudoacacia）的幼树为研究对象，采用树干液流技术，研究不同树木冠层吸收臭氧情况及其对环境因子的响应差异，以期为城市空气质量提升及林木栽培养护提供参考依据。结果表明：大气臭氧浓度日均值夏季明显高于秋季，其变化规律呈单峰型；各树木夏季吸收臭氧日变化规律与树干液流相似，为单峰曲线，但其启动时间比液流晚3 h；不同树种臭氧吸收速率最大峰值及出现时间不同，国槐、栾树和旱柳均在14:00时达到最大，其值分别为1.50、0.80、2.41 nmol·m-2·s-1，而刺槐则在12：00达到最大值为0.84 nmol·m-2·s-1；不同树种臭氧日累积量为旱柳（0.073 mmol·m-2）>国槐（0.042 mmol·m-2）>刺槐（0.025 mmol·m-2）>栾树（0.024 mmol·m-2）。各树木冠层臭氧吸收与环境因子间相关性检验和逐步回归方程（R2均在0.65以上）显示，各环境因子与臭氧吸收均呈极显著（P<0.01）相关，其中空气相对湿度呈负相关性；而回归方程表明多种因素综合影响下，树木臭氧吸收的关键因子为大气臭氧浓度、太阳辐射和VPD。
- Abstract:
- Four common saplings,namely Sophora japonica，Koelreuteria paniculata，Salix babylonica and Robinia pseudoacacia were used as materials,based on sap flow measurements,the differences of ozone uptake by different tree canopy and their response to environmental factors were studied,in order to provide data reference for urban air quality improvement and tree cultivation and maintenance.The results showed that the daily mean value of atmospheric ozone concentration in summer was significantly higher than that in autumn,and the variation law was unimodal.The diurnal variation of ozone uptook by trees in summer was similar to that of sap flow,which was a single peak curve,but its start-up time was 3 hours later than sap flow.The maximum ozone absorption rate of Sophora japonica,Koelreuteria paniculata and Salix babylonica reached the maximum at 14:00,which were 1.50,0.80,2.41 nmol·m-2·s-1,respectively,while that of Robinia pseudoacacia was 0.84 nmol·m-2·s-1 at 12:00.The daily ozone accumulation of different tree species was Salix babylonica (0.073 mmol·m-2)>Sophora japonica (0.042 mmol·m-2)>Robinia pseudoacacia (0.025 mmol·m-2)>Koelreuteria paniculata (0.024 mmol·m-2).The correlation test and stepwise regression equation (R2 were above 0.65) showed that all environmental factors were significantly correlated with ozone absorption (P<0.01),and the air relative humidity was negatively correlated.The regression equation shows that the key factors of ozone absorption by trees were atmospheric ozone concentration,solar radiation and VPD.
