Abstract: In order to understand the diversity and structure of macrobenthic communities in the intertidal zone of Yushan Island, we surveyed the diversity of macrobenthos at five sampling stations between March 2009 and January 2010. A total of 100 species of intertidal macrobenthos was identified. We quantified species diversity based on investigations of species composition, biomass and abundance. The results showed that: the average Shannon-Wiener diversity index (H')、Pielou index (J)、Margalef’s richness index (R) and Simpson’s diversity index (D) in different sections and seasons were 3.328 ± 0.109, 0.725 ± 0.021, 4.350 ± 0.216 and 0.823 ± 0.016, respectively. Shannon-Wiener (H') and Margalef’s richness indices (R) varied among sampling stations (H': F4,15=3.192, P<0.05; R: F4,15=5.623, P<0.01), meanwhile Pielou (J) and Simpson’s indices (D) demonstrated significant seasonal variation (J: F3,16=6.575, P<0.01; D: F3,16=3.359, P<0.05). Using an ABC (abundance biomass comparison) curve, we analyzed the structure of the intertidal community in Yushan Island and found that overall disturbance was not apparent except in summer.
