Plant communities and their diversity of Maqu Alpine Wetland

The sample belts were used to survey the plant communities and their diversity of Maqu Alpine Wetland. This study showed that 24 plant species belonging to 22 genera of 14 families were identified in this field survey, in which the Kobresia pygmaea was dominant, and the Polygonum viviparnm, Potentilla anserine, and Scirpus triquete were subdominant. In the life form components, the hemicryptophyte was dominant and accounted for 83% of the total. The vertical structure of plant communities were divided into three layers. The richness index (R1,R2), diversity index (Simpson diversity index D, ShannonWiener diversity index H) and evenness index (E1,E2) was 17.75, 1.50, 1.34, 0.39, 0.23, and 0.09, respectively.
