| 摘要 | [Objectives] This study was conducted to explore the characteristics of plant diversity of Jiangxia Wetland in Lhasa River basin. [Methods] Based on the survey data of 37 plant community in three types of sample plots of Jiangxia Wetland in the Lhasa River basin, this study analyzed the diversity of plant community in different habitats of Jiangxia Wetland from Pielou evenness, Margalef richness, Simpson and Shannon Wiener diversity indexes of different types and levels. [Results] The Pielou index, Shannon-Wiener index and Simpson diversity index of dry land was higher than those of other plots, while the Margalef species richness index of the ecotone of seasonally flooded and dry land was higher than that of other plots. The Pielou index, Shannon-Wiener index, Simpson diversity index and Margalef species richness index of composite plants were higher than those of other herbaceous plants. The Shannon-Wiener index, Simpson diversity index and Margalef species richness index of hygrophytes were higher than those of other plants, while the Pielou index evenness index of aquatic plants was higher than that of other plants. Annual or perennial herbaceous plants occupied the primary position in the study area, and shrub plants occupied a secondary position, and floating plants took the lowest position. [Conclusions] The results of this study can provide theoretical support or reference basis for the scientific management of comprehensive wetland systems such as wetland ecosystem restoration and plant diversity protection in Jiangxia Wetland. |
