Study on the ecological and environmental effect on meiofauna in Yundang Lagoon, Xiamen

Abstract

与大型底栖动物的研究比较,小型底栖动物的研究在我国相对薄弱且较少。为了了解小型底栖动物在筼筜湖的时空分布,分析外来物种沙筛贝与小型底栖动物的相互关系,探讨小型底栖动物是否能够作为筼筜湖生态系统健康评估的指标,在2008年6月、2008年9月、2008年12月和2009年3月,本研究选择筼筜湖5个潮下带取样站和2个红树林潮滩取样站进行小型底栖动物调查,首次在筼筜湖两种生境获得小型底栖动物的类群、密度和生物量,同时对筼筜湖自由生活海洋线虫的优势属进行了鉴定,并对筼筜湖小型底栖动物与水体环境的关系进行了分析。主要研究结果如下: 类群组成。四个季度采样共获得自由生活海洋线虫、桡足类、多毛类、寡毛类、...Less research on meiofauna were carried out compared to macrofauna in China. In present study, the spatial-temporal distribution of meiofauna in Yundang Lagoon was studied for the first time, to explore the relationship between meiofauna and the alien specie Mytilopsis sallei. Possibility of meiofauna as an indicator of the health assessment of ecosystem were also discussed in this research.Five s...学位:理学硕士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:2262006115233
