自然保护区的生物多样性测度 [PDF]

open access: yes, 2011
生物多样性是人类生存的基础,而自然保护区是生物多样性保护的重要方式,建立合理的生物多样性测度体系是自然保护区建设的重要方面.自然保护区的生物多样性包括三个方面:容量、通量和质量,它们从不同的侧面测度自然保护区的生物多样性.容量指自然保护区内生态系统类型、物种数的绝对多度和相对多度.物种丰富度是衡量生物多样性容量的较好的指标.通量是指不同自然保护区之间在生态系统类型或物种组成上的相似性与连通性,可以采用β多样性来衡量,如Cody指数和Li指数.当保护区之间的通量值较低时,需要进行整体插值,建立新的保护区 ...
