莆田互花米草入侵区大型底栖动物群落研究

2008年3月-12月对莆田市沿海互花米草（Spartina alterniflora）的入侵现状及分布区大型底栖动物群落进行调查研究。结果表明：仙游县枫亭镇、涵江区三江口镇沿海滩涂有较大面积的互花米草分布，在其他海域尚未发现。在枫亭镇辉煌村互花米草分布区高、中、低三个潮区共获得大型底栖无脊椎动物25种，其中节肢动物7种，环节动物16种，软体动物2种，生物量平均为156．1246±120．0180g·m^-2，平均密度为11253±9133ind·m^-2，与其他学者的研究相比属于较高水平。数量优势种为中国毛虾（Acetes chinensis Hansen）与中华蜾赢蜚（Corophium chinensis）等。

Studies on Macrobenthic Community on Spartina Alterniflora Invadedarea of Putian

The distribution of Spartina alterniflora in Putian coastalland and macrobenthic community at these areas were investigated from March to December, 2008. Results showed that Spartina alterniflora distributed at Xianyou Fengting, Hanjian Sanjiangkou on some scale. Macrofaunal were sampled from Spartina alterniflora distrubition area at Xianyou Fengting. There were 25 species of macrobenthos, include 7 Arthropoda, 16 Annelida, 2 Mollusc. Averge biomass were 156.1246＋120.0180g·m^-2 and average indensity were 1 1269＋9190ind·m^-2, higher than other studies. Acetes chinensis Hansen and Corophium chinensis were the superiority species at the density.
