Abstract: This paper studied the tree species composition and diversity of three Fungshui forests under different degrees of anthropogenic disturbance in Daling shan 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 distu rbance (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 DB H and tree height in the three forests decreased with increasing intensity of an thropogenic disturbance. Shannon-Wiener diversity index, Simpson diversity inde x, Margalef richness index, and Pielou evenness index all showed a consistent pa ttern of medium disturbance>high disturbance>low disturbance, being in accordanc e with intermediate disturbance hypothesis. The Whittaker’s β-diversity value under low, medium, and high disturbances was 0501, 0647, and 0889, respec tively, which better reflected the habitat heterogeneity of the forests under di fferent degrees of anthropogenic disturbance.
