新疆巴楚地区国家重点生态公益林植物群落生物多样性研究

Study on the biodiversity of major national ecological public welfare forests in Bachu Region of Xinjiang Autonomous Region

在对新疆巴楚地区国家重点公益林植物群落进行本底调查的基础上,采用物种重要值计算多样性指数、丰富度指数和均匀度指数,对巴楚地区国家重点公益林植物群落多样性进行了研究。结果表明:各群落总的丰富度和多样性较低,而且主要受草本层影响;木本层的丰富度和多样性都低于草本层,木本层和草本层均匀度差异不大。

Based on investigation of the plant communities of major national ecological public welfare forests in Bachu Region of Xinjiang, the species important values were used to calculate the diversity, abundance and evenness indexes, and to study the community biodiversity of major national ecological public welfare forests in Bachu Region. The results showed that the total abundance index of each community was low and mainly influenced by the aboundance of the herb layers. The important value of the shrub layers was higher than that of the herb layers. The difference of the evenness index between the shrub and herb in every communi ty was very small.
