| 摘 要： | 以长江口滨岸滩地生态系统一种常见的大型底栖动物无齿相手蟹(Sesarma dehaani)为研究对象，分析温度、盐度、重金属间相互作用等几个主要非生物因子对无齿相手蟹积累Cu，Zn，Pb，Cr，Ni的影响。结果表明，夏季无齿相手蟹对Cu，Zn，Cr，Ni的累积量高于其他季节，说明较高的温度有助于动物对重金属元素的吸收；秋季，无齿相手蟹体内的Pb含量与盐度显著负相关；春季，无齿相手蟹体内的Zn含量与盐度负相关；无齿相手蟹体内累积的Zn—Ni，Pb—Cr之间相关显著，二者均呈正相关。

| Abstract: | Sesarma dehaani, a kind of frequent macrobenthos in the tidal flat of Changjiang estuary is taken as the research object to analyze the effect of three leading abiotic factors,including temperature, salt and the interaction among different metals,to the accumulative concentration of Cu,Zn,Pb,Cr,Ni by Sesarma dehaani. Result shows that the accumulative concentration of copper,zinc, chromium and nickel by Sesarma dehaani in summer is higher than that in other seasons, which means that higher temperature does help to accumulate heavy metals by macrobenthos. In autumn, the concentration of lead in Sesarma dehaani shows dramatically negative correlation with salinity. In spring, the concentration of Zinc in Sesarma dehaani shows negative correlation with salinity. The correlation between Zn-Ni and Pb-Cr in Sesarma dehaani is dramatically positive correlation. |
