本文探讨台湾竹围红树林泥滩沉积物营养盐对大型底栖动物丰度的重要性。大型底栖动物丰度随季节波动。大多数底栖生物活动发生在沉积物顶部3厘米内。优势存款饲养者被发现的寡毛类，Paranais litoralis和Monopylephorus parvus，多毛类，Capitella sp. P. litoralis只出现在冬末夏初，其分布与沉积物温度。Capitella sp.的丰度与表层沉积物有机质含量相关。M.小袋鼠主要在春季招引。尽管碎屑可以提供底栖动物所需的大部分碳，但不稳定物质，特别是含氮物质的可用性有限。1993年10月和12月的一波可用氮可能提供了额外的营养物质，并刺激了从福尔斯晚秋到初冬的动物数量。
The importance of sediment nutrients to the surface macrofaunal abundance in a mudflat of the Chuwei Mangrove forest, Taiwan was determined. Macrobenthic abundance fluctuated seasonally. Most benthic activities occurred within top 3 cm of sediment. Three dominant deposit feeders were found: the oligochaetes, Paranais litoralis and Monopylephorus parvus, and the polychaete, Capitella sp. P. litoralis appeared only from late winter till early suirmer, and its distribution was correlated with sediment temperature. The abundance of Capitella sp. was correlated with surface sediment organic content. M. parvus recruited mainly in the springtime. Although the detritus can provide most of the carbon needs for benthic animals, the availability of labile materials, especially nitrogen-containing material, was limited. A pulse of available nitrogen in October and December 1993 might have provided additional nutrients and stimulated animal abundance from late falls till early winter.
