| 摘 要： | 在对湖南省生物多样性现状进行调查的基础上，采用包括物种丰富度、生态系统类型多样性、植被垂直层谱的完整性、物种特有性、外来物种入侵度5个评价指标的生物多样性综合评价方法，以县(区)为单位，对湖南省125个县(区)进行了生物多样性评价. 结果表明:有51个县(区)的生物多样性状况为“高”，有53个县(区)为“中”，有12个县(区)为“一般”，有9个县(区)为“低”. 评价结果与湖南省生物多样性的实际情况基本相符，基本能反映出湖南省植物多样性的整体分布状况.

| Abstract: | In this paper, the biodiversity in 125 counties of Hunan Province was evaluated on the basis of investigation of biodiversity patterns using five assessment indicators: species richness, diversity of ecosystem types, completeness of vertical stratification of vegetation, endemism, and extent of alien species invasion. The results show that 51 of 125 counties have high biodiversity, 53 counties have moderate biodiversity, 12 counties have medium-low biodiversity, and 9 counties have low biodiversity. These data are consistent with the actual biodiversity status, and generally reflect the distribution of plant species diversity in Hunan Province. |
