Ca and Mg contents in 41 kinds of soil samples in China were measured and the regional distributions of Ca and Mg contents in the soil are presented as contour maps in this paper. The Ca and Mg contents in the soil samples are discussed in relation to the chemical components, the acid-buffering ability (ΔC<SUB>b</SUB>) of the atmospheric aerosol, and the acidification of precipitation. The contents of Ca and Mg decreased gradually from the north to the south and from the west to the east. The Ca content ranged from 0.01 to 16.3% with the average of 1.54%, and Mg varied from 0.2 to 4.0% with the average of 0.78%. The acid-buffering ability of aerosol in Northern China was 375∼1,710 neq/m<SUP>3</SUP>, which was much higher than -92.8∼71.3 neq/m<SUP>3</SUP> in Southern China. Generally, acid rain has been observed in Southern China but not in Northern china. The regional distributions of acid- buffering ability of atmospheric aerosol and the acidity of precipitation coincided with the distribution of Ca and Mg contents in the soil. These results indicated that there are strong relationships among the Ca and Mg contents in soil, the acid-buffering ability of atmospheric aerosol and the acidification of precipitation in China.
