| 摘 要： | 本文就酸雨与四川东部华山松大面积枯死的关系进行了论证。华山松严重发病区巫山县梨子坪林场5-8月份大气降水的pH值分别为6.06、5.80、6.05、5.78;土壤pH值为5.20-6.65。用pH为3.5、4.5、5.5的稀硫酸模拟酸雨试验,喷雾200 h、400 h后对华山松的生长量、干重、叶绿素含量无不良影响,实验证明四川东部华山松大面积枯死与酸雨无关。

| Abstract: | This paper summarized the relationship between acid rain and death of Pinus armandi. In severe affect areas of Liziping Forest Farm, Wushan County, the average acidity in the rain per month, from May to August were pH 6.06, 5.80, 6.05 and 5.78 respectively. Experiments were conducted by simulation testing, spraying diluted sulphuric acids in pH 3.5, 4.5 and 5.5 on the trees. Results showed that there were no harmful effects either on growth, dry weight or chlorophyl contents of P. armandi. It demonstrated that so called 'acid rain' was not the causal agent responsible for the death of trees in vast eastern mountainous area 1600 m above sea level in Sichuan Province. |
