为进一步了解红树林区大型底栖动物群落与红树林生境之间的关系,2006年4、7、10月和2007年1月月底分别对集美凤林和翔安山后亭人工种植红树林区大型底栖动物进行了定量调查．主要研究结果如下：2006-2007年于集美凤林和翔安山后亭人工种植红树林区分别采集获得大型底栖动物65种和68种．凤林和山后亭红树林区4个季度大型底栖动物年平均栖息密度分别为5575．1和1625．6 ind?m-2；年平均生物量分别为85．60和50．59 g?m-2．大型底栖动物的年平均栖息密度、年平均生物量方面凤林红树林区均高于山后亭．大型底栖动物群落组成、年平均栖息密度和年平均生物量的差异主要与两片红树林区的沉积物粒径和有机质含量有关．集美凤林红树林区沉积物中有机质含量较高、底质粒径较细,为机会种沼蚓(Limnodriloides sp．)提供了合适的栖息环境；而翔安山后亭红树林区沉积物中有机质含量较低、底质粒径较粗,更适合甲壳类穴居和潜居。
為進一步瞭解紅樹林區大型底棲動物群落與紅樹林生境之間的關繫,2006年4、7、10月和2007年1月月底分彆對集美鳳林和翔安山後亭人工種植紅樹林區大型底棲動物進行瞭定量調查．主要研究結果如下：2006-2007年于集美鳳林和翔安山後亭人工種植紅樹林區分彆採集穫得大型底棲動物65種和68種．鳳林和山後亭紅樹林區4箇季度大型底棲動物年平均棲息密度分彆為5575．1和1625．6 ind?m-2；年平均生物量分彆為85．60和50．59 g?m-2．大型底棲動物的年平均棲息密度、年平均生物量方麵鳳林紅樹林區均高于山後亭．大型底棲動物群落組成、年平均棲息密度和年平均生物量的差異主要與兩片紅樹林區的沉積物粒徑和有機質含量有關．集美鳳林紅樹林區沉積物中有機質含量較高、底質粒徑較細,為機會種沼蚓(Limnodriloides sp．)提供瞭閤適的棲息環境；而翔安山後亭紅樹林區沉積物中有機質含量較低、底質粒徑較粗,更適閤甲殼類穴居和潛居。

In order to further understand the relationship between mangrove habitat and macrofaunal community,macrofaunal sampling was carried out at Fenglin and Shanhouting mangrove wetlands in Tong’an Bay in April,July,October of 2006 and January of 2007,respectively.The main results were shown as follows:65 and 68 species of macrofauna were obtained in Fenglin and Shanhouting mangrove wetlands,respectively.And the annual mean abundance of macrofauna in Fenglin and Shanhouting were 5 575.1 ind?m-2 and 1 625.6 ind?m-2 ;the annual mean biomass of macrofauna in Fenglin and Shanhouting were 85.60 g? m-2 and 50.59 g? m-2 .Both the annual average abundance and biomass of macrofauna in Fenglin were higher than those in Shanhouting.Difference on macrofaunal community composition,annual average abundance and biomass obviously related to the sediment grain size and organic matter content.Finer sediment particle size and higher organic matter content of sediment in Fenglin mangrove wetland provide a suitable habitat for the opportunistic species such as Limnodriloides sp.,while in Shanhouting mangrove wetland with lower organic matter content and coarser sediment grain size,the habitat is more suitable for crustaceans who prefer caving and excavating.
