| 摘 要： | １９９６年对厦门三处潮间带和两口虾池的小型底栖动物进行了调查。结果表明，小型底栖动物主要类群自由生活海洋线虫。此外，还有底栖桡足类、多毛类和寡毛类。三处潮间带海洋线虫的平均密度为６０．１３个／ｃｍ＾２，占小型底栖动物平均密度的９４．４６％。除了鸡屿中潮区和低潮区外，其他潮漳带海洋线虫与底栖桡足类丰度比度多在１６．３以下，表明厦大海边和大屿潮间带未受明显污染。刚放虾苗的虾池，小型底栖动物贫乏，随着时

| Abstract: | Meiofauna in three Xiamen intertidal mudflat and two shrimp ponds were investigated in 1996. The main group of meiofauna was nematode. Other groups such as benthic copepoda,polychaete and oligochaeta were found. The average abundance of nematode on three inter-tidal mudflat in Xiamen was 60. 13 ind. /cm2, which accounted for 94. 46% of meiofaunal av-erage abundance. The abundance ratio between nematode and benthic copepoda was no more than 16. 3 near middle and low areas on Jiyu mudflat, which showed that intertidal zones off Xiamen University and Dayu Island were not polluted obviously. The abundance of meiofau-na in shrimp ponds was poor at the beginning of shrimp culture and increased with time, and reached stable after one month, due to ecological environment at shrimp pond, and meiofau-nal breeding character. High abundance ratio between nematode and benthic copepoda at shrimp ponds was related to disturbance. |
