UV-B辐射增强对生态系统矿质营养循环的影响

Effect of Enhanced UV-B Radiation on the Cycling of Mineral Nutrient of Ecosystem

人类活动产生的氟氯烃等化合物对大气的污染造成臭氧损耗,引起地面UV-B辐射增强,进而造成对地球生态系统的影响。本文综述了UV-B辐射增强对陆地生态系统和水生生态系统矿质营养影响的国内外研究态势,尤其是对两者矿质营养循环的影响研究,并就目前研究状况,提出未来研究方向。

The results of studies show that enhanced Ultraviolet radiation (UV-B, radiation,broad band. 280～400nm) on earth surface could produce negative effects on creature and would be bound to impact on ecosystems. This article mainly discuss about the effect of Enhanced UV-B Radiation on mineral nutrients of land-system and water-system with summing up the developing at home or aborad,esp.the effect of Enhanced UV-B Radiation on their cycling.According to researching situation now and suggesting to studying direction in the future.
