摘要
分析了2004年4月天津塘沽高沙岭潮间带大型底栖动物的情况。共采集到现存大型底栖动物16种,生物量(湿重)为119.24g/m2,生物密度为190.00个/m2。定量样品中的生物可以分为4大类,软体动物占主要地位,占总生物量的68.89%。相关分析表明,此潮间带的生物量较低,次级生产力的估算值为14.80g/m2(去灰干重);主要营养级间的生产力比值明显小于林德曼效率,因而生态结构存在不稳定的环节。
The investigation of Macrobenthos in Gaoshaling intertidal zone in Apr. , 2004 was reported in this paper. It was found that the Macrobenthos biomass was 119. 24g/m^2 （wet weight） , the biological density was 190.00ind/m^2. There were 16 species of Macrobenthos found in the investigation zone. The quantitative samples included 4 sorts of Maerobenthos, and mollusk was in the highest flight. It occupied 68.89% of the whole biomass. The results were compared with that of Lvjuhe, the adjacent intertidal zone. The biomass of this zone was lower, and the second productivity was estimated as 14.80g/m^2 （AFDW）. The ecological structure was unreasonable in a certain extent.
