抄録: Plants absorb gaseous air pollutants from the atmosphere through stomata. In this study, the absorption of CO_2, SO_2 and NO_2 by the vegetation classified into 11 categories based on land use was evaluated from the net and gross production, and the area of each vegetation in Sakai city divided into 48 sections. As a result, the distribution of the gas absorption rate per unit area showed the gradient from the south mountainous area to the northwest commercial and industrial area. The total annual absorption of CO_2, SO_2 and NO_2 by the vegetation in Sakai was estimated to be 87kt, 66t and 77t, respectively. The absorption of SO_2 and NO_2 was equivalent to 9.9 and 2.0% of the exhaustion from the major stationary sources in Sakai, respectively. Moreover the NO_2 absorption was equivalent to 0.8% of the total NO_2 exhaustion in Sakai. The vegetation in the tumuli in Sakai was the efficient sink of the gases, particularly NO_2.
