摘　　要：经测定1989年8月青海省五道梁的6次降水样品的数据是:pH值为6.88—7.50;电导率为7.7—35.0 μΩ/cm。降水化学组成具有与阿拉斯加地区测定值相一致的数值。分析结果表明:五道梁地区的空气清洁,人为影响很小,是适合于建立全球大气本底污染监测站的地区。It has been determined that the chemical composition of precipitation at Wudaoliang, Qinghai Province. The data of 6 samples of precipitation in August of 1989 show 6.88-7.50 of pH value; 7.7-35.0 /μΩ / cm of electric conductivity.The chemical composition of precipitation have equal level to data which has been determined in Alaska area . The results show that the air over Wudaoliang area is very clean, and anthropogenic effect is little. The Wudaoliang station is suited to set up a globle baseline station of background air pollution monitoring .
