| 摘 要： | 本文对四川自然保护区降水化学组份的研究,作为四川盆地的酸雨背景值,并与国内其它降水背景值进行比较。研究结果表明四川降水背景值pH>5.6,pH值变化相对比较稳定,降水化学组份浓度较低,也说明盆地外来源的污染物对盆地内的贡献是不明显的。

| Abstract: | The composition of precipitation has been studied in Sichuan natural conservation areas.It is taken as the acid precipitation quality background of Sichuan Basin. The result shows that precipitation quality background in Sichuan pH>5.6. The range of pH value Changes a little. The concentration of Chemical compositious in precipitation is at a lower level. It is not obvious that external pollutants contribute to The precipitation in Sichan Basin. |
