| Abstract: | The results of studies show that enhanced Ultraviolet radiation (UV-B, radiation,broad band. 280～400 nm) 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. |
