| 1 | 鲁西北平原玉米地涡度相关臭氧通量日变化特征显示文摘近地面高浓度臭氧(O3)对植物生长发育和光合作用等都有副作用.基于O3通量(特别是植物气孔吸收)的评价指标被认为比基于O3浓度的指标能更好地反应O3对生态系统的影响.本文报道了利用涡度相关技术进行农田生态系统(玉米地)O3通量的观测结果,初步分析了该地区夏玉米地上O3浓度、沉积速度(Vd)和臭氧通量(Fo)的日变化规律及其与生态环境条件的关系.结果表明:(1)观测期间(2011年8月9日至9月28日),30 min平均O3浓度存在明显的日变化规律,其最低值(16.5 nL L-1)和最高值(60.1 nL L-1)的出现时间分别为6:30和16:00左右.白天(6:00~18:00)和夜间(18:00~6:00,下同)的O3浓度分别为(39.8±23.1)和(20.7±14.1)nL L-1(平均值±标准差),瞬时O3浓度最大值为97.5 nL L-1.O3浓度受太阳辐射和温度影响比较明显.(2)无论白天还是夜间,近地层O3都是向下运动的.Vd日变化规律表现为夜间小而平稳、上午快速上升、中午前后大而平稳以及下午快速下降的过程.白天和夜间的Vd平均值分别为0.29和0.09 cm s-1,最大值为0.81 cm s-1.白天Vd的大小受作物生长期的影响,而Vd的日变化受太阳辐射和相对湿度的影响最为明显.(3)O3通量的日变化受O3浓度和Vd的共同影响,白天和夜间的平均O3通量(Fo)分别为-317.7和-70.2 ng m-2 s-1.Fo与CO2通量(Fc)和潜热通量(LE)的相关关系比较显著,通过比较白天和晚上Vd的差别,可以判断白天的气孔吸收是玉米地上大气O3主要的汇. | 朱治林 孙晓敏 董云社 赵风华 Franz X MEIXNER | 2014 | 中国科学:地球科学2014，44，2： | 12 |
| 2 | Diurnal variation of ozone flux over corn field in Northwestern Shandong Plain of China显示文摘High concentration ground-level ozone(O3)has adverse effects on plant growth and photosynthesis.Compared to the O3concentration-based index,the O3flux-based(especially stomatal O3uptake)index has been considered the better criterion for assessing the impact of ozone on vegetation and ecosystems.This paper reports on a study of O3flux using the eddy covariance technique over a corn field in the Northwestern Shandong Plain of China.Diurnal variation of atmospheric O3concentration,deposition velocity and flux,and their relationships to environmental factors are analyzed.The results show that:(1)During the observation period(9 August–28 September,2011),there was a strong diurnal variation of O3concentration,with low(16.5 nL L?1)and high(60.1 nL L?1)O3mean concentrations observed around 6:30 and 16:00,respectively.Mean O3concentrations during daytime(6:00–18:00)and nighttime(18:00–6:00)were 39.8±23.1 and 20.7±14.1 nL L?1(mean±std),respectively.The maximum observed concentration was 97.5 nL L?1.The concentration was mainly affected by solar radiation and air temperature.(2)Whether daytime or nighttime,ground-level O3flux is always downward.The diurnal course of mean deposition velocity was divided into 4 phases:a low and stable process during nighttime,fast increasing in early morning,relatively large and steady changes around noon,and quickly decreasing in later afternoon.Daytime and nighttime mean deposition velocities were 0.29 and 0.09 cm s?1,respectively.The maximum deposition velocity was 0.81 cm s?1.The magnitude of deposition velocity was influenced by the corn growth period,and its diurnal variation was significantly correlated with global radiation and relative humidity.(3)O3flux was affected by variations of both O3concentration and deposition velocity,with mean O3fluxes-317.7 and?70.2 ng m?2s?1during daytime and nighttime,respectively.There was strong correlation between O3flux and CO2flux or latent heat flux.By comparing the deposition velocities of daytime and nighttime,we infer that stomatal uptake was probably the main sink of ground-level O3. | ZHU ZhiLin SUN XiaoMin DONG YunShe ZHAO FengHua Franz X MEIXNER | 2014 | Science China Earth Sciences2014，57，3： | 5 |
