UV-B辐射对植物生理生态特征的影响研究进展

Research Progresses of the Impact of UV-B Radiation on Plant's Ecophysiology Characteristics

工业化进程的加速和人类活动的加剧引起了一系列的环境变化。其中,由臭氧破坏引起的紫外辐射的增加是目前人们面临的严峻问题。先就目前UV-B(紫外线B波段)辐射增加的现状,以及国内外关于UV-B辐射对植物生理生态的影响研究进行了概述;然后,对国内外关于植物对UV-B辐射增加的响应研究进行了总结;最后指出了研究的不足和后续研究的重点方向。研究成果对后续深入研究UV-B辐射对植物生理生态特征的影响具有一定的指导意义。

Accelerated industrialization and frequent human activities gave rise to environmental problems among which UV-B radiation caused by ozone destruction is increasing.In the present paper,the current status of in-creased UV-B radiation is introduced,and researches in China and abroad on the impact of UV-B radiation on plant’s ecophysiological characteristics are reviewed.Moreover,responses of plants to the increasing UV-B radia-tion are summarized,and the shortcomings of previous research and the focuses of future research are presented.
