国内外对酸雨研究颇多.本文所测石河子降水中性偏碱.一年共采雨雪水样品58份,pH M=7.35,其中 pH<5.5者为0,pH>7者计49份,占84.5%,降水偏碱的原因是碱性地表土壤→碱性风沙扬尘→碱性大气尘污染→碱性雨雪降水.故,表层土壤性质及成伤可影响降水酸度.
There are a lot of studies on acid rain at home and abroad.The precipitation of Shihezi is neutral and alkaline in this paper.A total of 58 samples of rainwater and snow water were collected in a year, pH = 7.35, pH = 5.5, pH = Accounting for 84.5% of the total precipitation, and the reason for the precipitation is that the alkalinity of alkaline surface soil → alkaline wind and dust → alkaline dust → alkali rain and snow precipitation, so the surface soil properties and trauma can affect the precipitation acidity.
