%X The impacts of CO 2 enrichment and soil drought on the S accumulation and distribution of plants were studied.The results show that CO 2 enrichment and soil drought can increase the S contents for different parts of w inter wheat,and decrease the S content o f soybean grains.Although,soil drought increases the S content of winter wheat grains,the reduction scal e of yield is bigger than the increasing scale of grain S content.The impact of soil drought on the S content of soybean grains is more serious than that on win ter wheat.Soil drought not only decrease s the grain S content,but also decreases the grain yield of soybean.The impacts of CO 2 enrichment and soil drought on s talk and leaf S contents for 3 dominant species in Mu Us sandland are relatively complicated,but the reduction scale of the dry mass is bigger than the changing scale of S content.The total S fixation under the situation of CO 2 enrichment and soil drought decreases,showing the n egative effect.
