【摘要】 本文对四川盆地不同土壤分布区内28个中小型水库进行水体对酸沉降敏感性调查,发现夹江丹陵等地属酸沉降敏感区。目前,盆地内水体酸化程度,pH,HCO₃二项均未达到美国内华达山区水平,夹江、丹陵等敏感区pH水平与内华达相当。更多还原

【Abstract】 In this paper, the sensitivity of water bodies to acidic precipitation of twenty-eight median and small reservoirs of varied soil distribution region in Sichuan Basin has been investigated. The results showed that Jiajiang and Danling were the sensitive areas. At present, the acidified degree of water bodies within the basin or the levels of pH and [HCO₃^-] were lower than those in Nevada Mountaineous area, U.S.A., The level of pH in the sensitive areas of Jiajiang and Danling was equivalent to that in Nevada Mountaineous area.更多还原
