摘要
为了比较不同生境的大型底栖动物功能群,根据在泉州湾蟳埔潮间带3种生境类型获得的大型底栖动物数据进行了分析。2011年4月-至2012年1月在泉州湾蟳埔潮间带获得大型底栖动物101种,其中浮游生物食者(Pl)、植食者(Ph)、肉食者(C)、杂食者(O)和碎屑食者(D)物种数分别为21种、18种、21种、26种和15种。光滩(沙滩)、互花米草和牡蛎石三种生境大型底栖动物物种数、平均栖息密度、平均生物量、多样性指数的优势功能群多样化,表明泉州湾蟳埔潮间带大型底栖动物功能群的复杂化和多样化,这种特征是潮汐、生境、底质粒径等环境因子共同作用的结果。潮汐导致潮间带的空间异质性(沉积物粒径的差异),空间异质性导致大型底栖动物功能群组成的差异。互花米草、牡蛎石构成了多种小生境,有利于众多大型底栖动物的栖息。还讨论了大型底栖动物物种鉴定水平和功能群划分标准不同对功能群研究结果的影响。
To study the functional groups of macrofauna in different biotopes, we analyzed the macrofauna data in three biotopes in Xunpu intertidal zone, Quanzhou Bay. A total of 101 benthic macrofauna were got. We divided the macrofauna into five functional groups, namely planktophagous group（ Pl）, phytophagous group（ Ph）, carnivorous group（ C）,omnivorous group（O） and detritivorous group（D）. The species number of Pl, Ph, C, O and D was 21, 18, 21, 26 and 15 respectively. Dominant functional groups of macrofauna in species, mean density, mean biomass and diversity index were various in sandy, Spartina alterniflora and oyster-stone biotopes. The distribution characteristic indicated the complication and diversity in functional groups of macrofauna in Quanzhou Bay intertidal zone, and the joint action of tide, biotope,sediment particle size and other environmental factors. Tides result in spatial heterogeneity（different in sediment particle size） on intertidal zone, and spatial heterogeneity results in different functional groups of macrofauna. S. alterniflora and oyster-stone constitute various niches, which had advantages to many macrofaunas. This paper also discussed the influences of accuracy in macrofaunal identification and functional group classification criteria on the results of functional group research.
