%X The impacts of O_3 and CO_2 concentration doubling on the soybean leaf development and biomass are studied by using OTC-1 open top chambers. The results show that O_3 and CO_2 concentration doubling can lead to the yellow leaf ratio increase and the green leaf ratio decrease. CO_2 concentration doubling causes positive effects on the soybean leaf area, leaf weight, weight of green leaf and yellow leaf, as well as biomass, while O_3 concentration doubling causes negative effects on those. The mixed ozone and carbon dioxide may alleviate the negative effect of ozone on soybean biomass. The negative effect of O_3 on soybean leaf is more obvious than CO_2 in O_3 and CO_2 combination lasting concentration doubling. Before the bulge kernel stage, the alleviating effect of CO_2 on soybean leaf is apparent in the treatment of O_3 and CO_2 in combination gradually to concentration doubling; while after the bulge kernel stage, the effect of CO_2 and O_3 on soybean leaf is similar, the increasing of soybean biomass follows the curve of natural growth.
