摘    要:介绍了一些有关紫外B辐射增强对植物及生态系统影响研究的新进展:1.许多研究已深入到分子水平;2.注意到对植物生长调控的研究;3.更加重视对植物防御、修复的研究;4.有关信号传导的研究日渐增多;5.对植物群体及生态系统影响的研究在不断扩大与加深;6.复合效应研究正在升温。推断今后在一段时间内,有关UV-B辐射对植物和生态系统影响的研究不但不会削弱,可能还会加强,特别分子水平的研究会大大增加,今后对群体和生态系统的研究会重视野外和长期效应的观测。我国在这一领域的研究起步晚,但近些年发展得较快,有部分研究已赶上国际研究进展的步伐。

关 键 词:增强紫外B辐射  植物  生态系统  影响  发展趋势  研究进展

Abstract:Recent advances about the effects of enhanced UV-B radiation on plants and ecosystems were reviewed in this paper.The following is noteworthy:1.Several studies have reached to molecular level;2.Studies on plant growth regulation caused by UV-B radiation were strengthened;3.More attention about plant recovery and DNA-repair induced by UV-B injuring has been paid;4.The researches about signal transduction induced by UV-B were gradually increased;5.Works about the effects on plant colonies and ecosystems were extended;6.The researches of the combination effects of UV-B on plants were increased.It is concluded that the studies of effects of UV-B radiation on plants and ecosystems will be intensified,especially at molecular level.Observations on field experiments and long-term effects of UV-B will be attached.Although the studies in this area in China started later,the development and progresses have been made in the past few years.Some of them has caught up with the world development.
Keywords:UV-B radiation  plant  ecosystems  research advances
