Analysis of species diversity and characteristics of Ormosia saxatilis natural community under two different intensities of disturbance

TL;DRAbstract

【Objective】Natural community structure and species diversity characteristics in Ormosia saxatilis field under two different intensities of disturbance were studied to provide theoretical references for community protection, conservation and sustainable utility of species diversity. 【Method】By using conventional coenology investigation method with six typical community plots, the characteristics of species diversity of Ormosia saxatilis communities under two different intensities of disturbance were analyzed based on species richness index, the Shannon-Wiener and Simpson biodiversity index, and the pielou evenness index. 【Result】The plant of phanerophytes occupied the plots communities of the two places, and the tropical ingredients had a slight advantage. There were 29 species of vascular plants, belonging to 25 families and 26 genera in the Qianling hill community plots. And there were 74 species of vascular plants, belonging to 40 families and 59 genera in the Bijia hill community pl
