| 摘 要： | 1985—1986年对重庆南山马尾松林衰亡与酸雨的关系进行了研究。四个月的雨水监测表明南山酸雨况情严重。酸雨频率百分之百,平均pH4.2—4.4,最低pH3.6—4.0。土壤酸化程度较重(pH3.7—4.0)。土壤酸化的主要原因是酸雨的输入。濒死树针叶中锰和钴元素大为减少,与土壤中这两种元素的减少相对应。濒死树针叶中铝大量积累,土壤中活性铝增多和铝钙比增大。初步肯定酸雨是南山马尾松衰亡的重要原因之一。

| Abstract: | The decline of a masson pine forest of some 2,000 ha located on the south bank of the Yangtze River near Chongqing were investigated. The results of rain water monitoring for four months indicated that the frequency of acid rain was 100% and the average pH of the rain water ranged from 4.2 to 4.4 with minimum observed values around 3.6 to 4.0, which caused a drop of forest soil pH to a range of 3.7 to 4.0. The contents of Mn and Co in the needles of dying trees decreased significantly,together with a decrease of soil contents of these elements, while A1 content in the needles accumulated to a level three times higher than that of normal. The acid rain in the area is obviously the main reason causing the decline of the forest. |
