| 摘 要： | 利用稳定碳同位素技术,分析了海南岛新村湾海草床中主要鱼类及大型无脊椎动物的食物来源。结果显示,有机碳源δ13C值的变化范围为-16.9‰--6.8‰,以海草叶片及其碎屑最高(-7.8‰ ±0.2‰),悬浮颗粒有机质(POM)最低(-16.9±0.2)‰,而附生藻类(-12.0±0.9)‰和沉积物有机质(SOM)(-13.2±0.2)‰居中。消费者δ13C值的变化范围为-15.4‰--6.4‰,表明其食物来源较广。IsoSource 混合模型计算结果表明,本海草床棘皮动物、多毛类、甲壳类和大部分的鱼类以海草为主要有机碳源,双壳类主要同化附生藻类和SOM的混合有机碳源,少数鱼类以POM为主要碳源。以上结果表明,海草是海草床中主要鱼类及大型无脊椎动物的重要食物来源。
