| 摘 要： | 通过测定常见树种的树皮、树叶的ｐＨ值以及对应的大气污染状况，研究了大气中污染物的含量对树木ｐＨ值的影响。结果表明，大气中ＳＯ２污染对植物ｐＨ值影响最大。黄杨、柳树等树叶、树皮ｐＨ值与大气酸性污染物含量呈显著的负相关。按酸性大小排序为：燃性污染物〉燃料型工业区〉交通稠度区〉非燃料工业区〉生活居住区。 |

| Abstract: | This paper deals with the effects of pollutants in atmosphere on pH value of trees by using the method of measuring tree pH value and the condition of atmosphere pollution.The results show that SO 2 concentration in the atmosphere has the most effective on tree pH value.The relationship between pH value of leaves and barks and acidic pollutants in the atmosphere was remarkably negative correlation.According to the average pH value,the sequence was as follows the area of industry >the area in traffic jam >the area of light industry>the residential area. |
| Keywords: | atmosphere pollution acidic pollutants trees pH value correlation |
