| Abstract: | Objective]The research aimed to study the effects of irrigation on alpine grassland during its recovery and reconstruction.Method] The irrigation and non-irrigation experiment was carried out around Eling Lake of Maduo County in 2007.At the same time,the plant species and biomass was investigated.Result] Species compositions and richness of plant irrigation area were more than non-irrigation area.The above ground biomass and underground biomass in irrigation area was higher than in non-irrigation area.The average above ground biomass and underground biomass was 83.5 and 2 112.2 g/m2,13.4 and 594.7 g/m2 higher than that of non-irrigation area.Conclusion] Irrigation was beneficial to the plant growth and the reconstruction of plant community. |
