| 摘 要： | 本文利用已有调查资料,分析了大小兰沟自然保护生物多样性特征,认为大小兰沟自然保护区的生物多样性主要表现在物种资源的丰富性、区系成份的复杂性、起源的古老性、珍稀物种的密集性和植被类型的多样性等方面。形成多样性的原因是生物口岸效应、地理环境效应、处女地效应共同作用的结果。区内的生物多样性具有很高的科研、科考及保护价值。

| Abstract: | This article deals with biodiversity features in Sichuan Big-small Langou nature reserve based on the existing survey data.Biodiversity of this nature reserve is mainly characterized by abundant species resources,complex floristic composition,ancient origin,intensive rare species and diversity of vegetation types.The interaction of the biological port effect,geographical environment effects and virgin land effect also bring about the biodiversity.Biodiversity of this nature reserve has a high value for scientific research and protection work. |
