    摘要:

    本文运用开顶式熏气装置研究重庆南山大气SO2污染与马尾松衰亡的关系。通过SO2模拟熏气试验确定了SO2对马尾松急性和慢性伤害阈值和可见伤害症状,长期定点SO2浓度监测结果表明南山马尾松衰亡区的大气SO2改度超过了马尾松的慢性伤害阈值。SO2浓度与马尾松衰亡程度的空间分布一致、衰亡中的马尾松针叶上出现的可见症状与SO2熏气实验中所出现的症状相似。现场空气过滤实验证明SO2污染是马尾松针叶受害的原因。

    Abstract:

    The relationship between the atmospheric SO2 pollution and the decline of the masson pine forest located in Nanshan on the south bank of Yangtze River near Chongqing was studied. This work included SO2 pollution monitoring, SO2 fumigation, filtered air experiment in situ,and analysis of sulfur content in needles. The results of air monitoring indicated that the SO2 pollution in this area was heavy, and the SO2 concentration in air was 0.35 mg/m3 averagely, with maximum 1.30mg/m3. The fumigation tests showed...
