摘  要：
研究了人为干扰对东莞市大岭山镇风水林群落树种组成及多样性的影响。多响应置换过程(MRPP)分析结果表明,风水林树种组成在轻度干扰与中度干扰(P=0.023,A=0.216)、重度干扰间(P=0.045,A=0.226)存在显著差异,而中度干扰和重度干扰间则不存在显著差异(P=0.124,A=0.148)。随着人为干扰强度的增大,轻度干扰、中度干扰和重度干扰下林木胸径和树高随之减小。Shannon-Wiener指数、Simpson指数、Margalef指数和Pielou指数一致呈现出中度干扰>重度干扰>轻度干扰的格局,与中度干扰假说相符合。轻度干扰、中度干扰和重度干扰下Whittakerβ多样性分别为0.501、0.647和0.889,较好地反映了3个风水林在不同人为干扰强度下的生境异质性。

摘  要：
This paper studied the tree species composition and diversity of three Fungshui forests under different degrees of anthropogenic disturbance in Dalingshan Town of Dongguan City,Guangdong Province.Findings from the analysis with multi-response permutation procedures(MRPP)showed that there were significant differences in the species composition between low disturbance and medium disturbance(P=0.023,A=0.216)and between low disturbance and high disturbance(P=0.045,A=0.226),while no significant difference was observed between medium disturbance and high disturbance(P=0.124,A=0.148).The average DBH and tree height in the three forests decreased with increasing intensity of anthropogenic disturbance.Shannon-Wiener diversity index,Simpson diversity index,Margalef richness index,and Pielou evenness index all showed a consistent pattern of medium disturbance>high disturbance>low disturbance,being in accordance with intermediate disturbance hypothesis.The Whittaker's β-diversity value under low,medium,and high disturbances was 0.501,0.647,and 0.889,respectively,which better reflected the habitat heterogeneity of the forests under different degrees of anthropogenic disturbance.
