摘要
[目的]研究水分灌溉对退化高寒草原恢复重建中的作用和影响。[方法]2007年在玛多县鄂陵湖边的高寒草原进行灌溉与非灌溉试验,并进行植物种类及生物量的调查。[结果]灌溉后高寒草原植物种类组成增加,物种丰富度高于非灌溉区;植物地上、地下生物量均比非灌溉区明显提高,灌溉区平均地上和地下生物量分别为83.5和2 112.2 g/m2,比非灌溉区地上和地下生物量增加13.4和594.7g/m2。[结论]灌溉有利于植物生长和群落的重建。
[ Objective ]The research aimed to study the effects of irrigation on alpine grassland during its recovery and reconstruction. [ Method] The irrigation and non-irrlgation 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/m^2, 13.4 and 594.7 g/m^2 higher than that of non-irrigation area. [Conclusion] Irrigation was beneficial to the plant growth and the reconstruction of plant community.
