The result shows: In this period, area of acid precipitation is 100, 000 km~2, area of heavy acid precipitation is 32, 000 km~2; acid precipitation area is forecast to surpass 150, 000 km~2 in 2000, area of heavy acid precipitation is up to 60, 000 km~2.

• 结果表明:在现阶段；盆地内降水酸化面积达到10万km~2；重酸化区为3.；2万km~2；预计到2000年时；降水酸化区将超过15万km~2；重酸化区也将达6万km~2以上。
