| Abstract: | Objective] The research aimed to study the effects of irrigation on the plant diversity in Xilamuren Grassland, and to provide theoretical foundation for its＇ ecology recovery. Method] Based on the grassland restoration experiment in Xilamuren Grassland, the plant community diversity under different irrigation conditions in enclosed grassland was analyzed. Result] The results showed that the water volume was the important factor in determining the vegetation growth in desert grassland, and under different irrigation conditions, the diversity indices differed significantly. Conclusion] The plant diversity index was sensitive to water volume in temperate desert grassland. |
