• Acid deposition
• Critical loads

The acid-deposition critical loads for 80 surface-waters in southern China were calculated using a dynamic acidification model--MAGIC. The results show that the acid-deposition critical loads for most of these surface-waters are quite high, with values higher than 2 kmol&middothm-2&middota-1 and have evident spatial distributions. The surface-waters in southwestern China have the higher critical loads than those in eastern and central China. The main reason is that the soil sensitivity to acidification decreases from South China and East China to Southwest China. Surface-water acidification is not likely to become a severe regional problem in China but acidification of some mountainous surface-waters should be addressed.
