摘要 利用静态箱法研究了羰基硫 (COS)和二甲基硫 (DMS)在绿化草坪与大气之间的交换 .在秋季 ,草坪对COS的吸收通量为 0 75— 1 4 5 μg·m- 2 ·h- 1 ,对DMS的排放通量为0 0 5— 0 35 μg·m- 2 ·h- 1 .COS和DMS的交换通量与环境温度、光照及初始浓度等因素有关 ,其中 ,周围大气COS的浓度对草坪吸收COS的影响最为明显 .草坪对COS的吸收通量与DMS的排放通量呈正相关 ,相关系数 (R2 )大于 0 7.此外 。 The exchanging fluxes of carbonyl sulfide(COS)and dimethyl sulfide(DMS)were investigated by using static method between lawn and atmosphere.In fall,the COS uptake rates for lawn were 0 75—14 5μg·m -2 ·h -1 and the DMS emission rates were 0 05—0 35μg·m -2 ·h -1 .The exchange rates of COS and DMS were determined by air temperature,light,ambient concentration of COS and so on.The effect of ambient concentration of COS on the exchanging flux of COS was the key factor among the investigated factors.The COS uptake fluxes and DMS emission fluxes for lawn had good positive correlation,and the coefficient( R 2)is better than 0 7.In addition,the vertical distribution of COS also showed significant COS uptake by lawn.
