酸雨对植物的影响研究进展

本文综述了酸雨在个体水平上对植物形态结构、植物生理生化、逆境生理等方面影响的研究:酸雨影响叶片中的细胞器、破坏叶片的膜系统、腐蚀叶肉组织;破坏花的结构;酸雨对植物的出苗率没有明显的影响,但是对植物的出苗速度有一定的抑制作用;酸雨还影响植物的光合作用和叶片的N代谢;酸雨淋洗植物造成植物营养元素的析出,使得植物营养失衡;在一定程度上抑制植物的营养生长和生殖生长。并指出在包括酸雨在内的多因素的综合影响研究、酸雨对植物影响的机理研究、酸雨对植物影响的长期定位系统研究及尺度转换等方面还有待进一步的发展和完善。

Research Progress of the Effect of Acid Rain on Plant

The paper summarized the effects of acid rain on the morphology and structure of plants,the physiology and biochemistry of plants,the stress physiology from the level of individuals.Acid rain has the effect on the organelles of leaves,erodes the mesophyll tissues and destroys the structures of flowers;Acid rain has no obvious effect on the rate of emergence,but inhibits on the pace of emergence to some extent;And acid rain has effect on the photosynthesis and the nitrogen metabolism of plants;Acid rain leaching makes the precipitation of nutrient elements in plants,furthermore causes the unbalance of the nutrients in plants;Acid rain also has inhibition on the nutrition growth and reproduction.And the paper pointed out the synthetical study of the multiple-factor including acid rain,the mechanism study of the effect of acid rain on plants,the long-term localization system study of the effect of acid rain on plants and the scale conversion needed to be developed and perfected.
