Univariate and multivariate methods were used to study soft-bottom macrobenthos collected in December 2002 from the coastal waters of Singapore. The univariate parameters and community structure of benthic communities were related to environmental variables. Three samples were taken with a 0.1 m2 Van Veen grab (33 x 30 x 15 cm) at each station from 12 sampling stations of two different geographical areas. The water depth ranged from 6.5 m to 34.0 m. The mean values of species number, abundance and species diversity (H') were 24 species/grab, 77 animals/grab and 3.35/grab, respectively. A total of 172 species was recorded. Total petroleum hydrocarbons were strongly negatively related to species number, abundance and species diversity, suggesting that petroleum hydrocarbons have harmful effects on macrobenthic communities. The BIO-ENV analyses for all stations identified median particle size, silt-clay content, salinity and Zn as the major environmental variables influencing the infaunal patterns. However, separate analyses for two areas produced stronger correlations and different best-correlated environmental variable combinations. Total petroleum hydrocarbons were the only common factor in both areas, showing the importance of petroleum contamination in determining the community structure of benthic infauna in Singaporean waters.
采用单变量和多变量方法研究了2002年12月从新加坡沿海水域采集的软底大型底栖生物。底栖生物群落的单变量参数和群落结构与环境变量相关。在两个不同地理区域的12个采样站，每个站点用0.1平方米的Van Veen抓斗（33×30×15厘米）采集三个样本。水深范围为6.5米至34.0米。物种数量、丰度和物种多样性（H'）的平均值分别为24种/抓斗、77只动物/抓斗和3.35/抓斗。共记录了172个物种。总石油烃与物种数量、丰度和物种多样性呈强烈负相关，表明石油烃对大型底栖生物群落有有害影响。对所有站点的BIO-ENV分析确定中值粒径、粉砂-粘土含量、盐度和锌是影响底内动物分布模式的主要环境变量。然而，对两个区域的单独分析产生了更强的相关性和不同的最佳相关环境变量组合。总石油烃是两个区域唯一的共同因素，表明石油污染在决定新加坡海域底内动物群落结构方面的重要性。
