| 摘 要： | 通过测定白云山马尾松Pinusmassoniana、台湾相思Acasiaconfusa植物光合特性和叶片含氟、硫量 ,并将广州市城区及白云山测点大气污染、酸雨等污染特征和发展趋势 ,与大气污染、酸雨影响植物的阈值和剂量 -反应关系进行综合分析 ,评价广州市大气污染对白云山森林植物生态环境的影响。结果表明 ,位于白云山山南 (麓湖 )公路边的植物光合系统和细胞膜均产生明显变异 ,由汽车尾气衍生的光化学氧化剂污染物和酸雨是主要的影响因素。说明广州市大气污染已给白云山森林植被造成一定的损害 ,这种损害影响是低剂量长期的综合慢性效应 ,最终将导致森林的衰退 ,应引起重视。

| Abstract: | Photosynthetic character, fluorin and sulfer of leaves of %Pinus massoniana% and ?asia confusa% on Baiyun Mountain were tested. The character and development trend of air pollution and acid rain of Guangzhou urban city and Baiyun Mountain, and their effects on plants depending on the dose|response functions and thretics were analyzed.The effects of air pollution of Guangzhou on the plant ecological environment of the forest on Baiyun Mountain were assessed. |
