| Abstract: | This paper deals with the effects of SO2 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 thatthe plllutants in the atmosphere has the most effective on tree pH value.The relationship between pH value of and acidic pollutants in the atmosphere was remarkably negative correlation. |
