| 摘要: |
| 综述了尘污染对植物和植物群落的生理和生态作用和影响,并初步探讨了其原因和机制。尘污染能影响植物的光合作用、呼吸作用和蒸腾作用,并携带有毒性污染物穿透进入植物组织。尘污染会导致植物发生可见的伤害症状,引起生产力的下降。大部分的植物群落也会受到尘的影响而改变群落结构。今后要加强对自然条件下尘对植物影响的深入研究和植物不同种类间对尘敏感性的差异的研究。 |

| Abstract: |
| This review describes the physiological and ecological effects of dusting pollution on plants and plant community,and discusses the reasons and mechanisms of those effects. Dusting pollution may affect photosynthesis,respiration,transpiration and allow the penetration of phototoxic pollutants. Visible injury symptoms may occur and generally there is decreased productivity. Most of the plant communities are affected by dust deposition so that community structure is altered. Future works should be focused on detailed studies in natural systems and the difference of sensitivity to dust among plant species. |
