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,相关系数都在0.87以上。

摘  要：
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.
