抄録

The distributions of acid rain with the annual mean pH of rainfalls and acid rain frequency of yearly precipitation in South China are described for the period of 1991-1995. The areas suffering from heavy acid rain were the Sichuan Basin, Guizhou, Hunan and Jiangxi (SGHJ) where is the center of South China. Some climate features in SGHJ are summarized about cloud, precipitation, and wind. The formation reasons of acid rain are discussed. The lowest annual mean pH of rainfalls was 3.8, and the acid rain frequency of yearly precipitation exceeded 90% in several cities. The most fl ourishing districts where the energy consusmption is greatest is not in SGHJ but in the coastal area. The climate characters in SGHJ such as cloudy, moist and weak wind, must be the important factors for the acid rainfall, although SO₂ emission is the original cause. The maximum annual mean of total cloudiness canopies the main part of Sichuan-Guizhou where the acid rain originated in China and is a part of acid rain region all along. The annual rainfall amount in SGHJ is large but slightly less than that of the southeast cast. However, its annual mean of rainy days is higher than that of the coast. The prevailing wind speeds, directions and frequencies in SGHJ, and its geographical features, are unfavorable to diffusion.
