| 摘 要： | 采用模拟酸雨喷雾和ＳＯ２开顶式熏气，研究了酸雨和ＳＯ２复合作用对西红柿，胡萝卜和棉花等农作物产量的影响及其机理。通过模拟试验，发现酸雨和ＳＯ２使农物生产受阻，产量降低，其二者的昨合作用明显高于单一因素的作用，但其交互作用不显著。并通过模拟的盯关方程计算出农作物产量损失４的污染物阀值。

| Abstract: | The effects of acid rain and sulphur dioxide alone and in combination on tomato,carrot and cotton was studied by simulated acid rain irrigating and SO2 exposure. It was found that the simulated acid rain and sulfur dioxide could inhibit the growth of crops in a degree and reduce the productivity. The synthetic effeCt of acid rain and sulfur dioxide was more notable than alone, but their mutual effect was not marked. |
