近年来,我国不少地方发现酸性降水,特别是西南重庆、贵阳地区尤为严重[1]。国内外一些文献曾报道:酸性降水能影响生物的生长发育,降低生物产品的产量和质量,甚至引起鱼类和森林的死亡,破坏生态平衡[2,4]。 |
英文摘要 |
The paper gives a general description of the effects of simulated acid rain on tree leaves. The experiments have been done in Hunan Experimental Station of Forest Ecology. After the simulated acid rain were sprayed upon tree leaves, there appeared some symptoms:discoloration of greens, tissue necrosis, dewatering and early withering. And injurious extents on leaves were fundamentally due to the rain acidity, duration of spraying and conditions of sunlight and temperature. However, because of different tissue structures of the tree leaves, their resistant capacity were varied. |
