摘要

运用β多样性测度公式探讨了不同人为干扰强度(CK天然林、A级择伐更新、B级皆伐迹地天然更新、C级皆伐迹地人工促进天然更新、D级杉木林)对福建省武平县米槠林乔木层的影响。结果表明

应用二元属性数据的多样性测度方法

所测的β多样性测度(βWS

βC

βR

βT)随着干扰强度加大逐渐上升

而群落相似性指数(CJ和CS)随着干扰强度加大逐渐下降;应用数量数据的β多样性测度方法

所测β多样性指数(CN

CMH)随着干扰强度加大逐渐下降。每个测度公式相关关系都很紧密

Abstract

The effects of the different intensities of artificial disturbances on the tree layer(CK

the original Castanopsis carlesii forest;class A

the regeneration by selected cutting;class B

the natural regeneration in clear-cutting land;class C

the artificial measures promoting regeneration

and class D

Chinese fir stand) of the Castanopsis carlesii forest were studied using formula of β diversity in Wupin County

Fujian Province.The results showed that the β diversity indices were measured by binary data(β_(WS)

β_C

β_R

β_T) ascended gradually with the increasing of disturbance intensities

but the simility coefficients of community(C_J

C_S) droped down gradually as the disturbance intensities increases

and so on the β diversity indices measured using numberical data(C_N

C_(MH)).Relations of every measurement formula are very compact and coefficients of correlation all exceeded 0.87.
