| 摘 要： | 生物多样性保育是当前国际生物学研究和实践的重要领域，目前计算生物多样价值均是人为因素占主导地位，不能确切反映实际价值。本文研究了基于Shannon Wiener指数、增加濒危指数修正和增加特有种指数再次修正的3种对森林生态系统物种多样性保育价值评估方法，并以云南省第7次森林资源清查数据对3种方法进行了论证，结果表明增加特有种指数再次修正的方法能够科学合理地反映出物种多样性保育价值。

| Abstract: | Biodiversity conservation is an important field to international biology research and practice.At present,human factors occupy the dominant position to count the biodiversity value,which could not exactly reflect the actual value of biological diversity.In this paper,three assessing methods for species diversity conservation of forest ecosystem were studied,and data of the 7th forest resources inventory from Yunnan Province was analyzed to verify the methods.The results showed that the method with Shannon-Wiener index adding endangered index and endemic species index to amend could scientifically reflect the reasonable conservation value of species diversity.The final approach reflected three most important aspects of objective existence of the biological diversity.It could avoid the influence to assessing results owing to human factors,but also reflect the science and rationality of assessment,help to further strengthen the protection and rational utilization of biological diversity. |
