| 摘 要： | 本文于2012年4月、7月与10月以及2013年1月与4月，对福建省云霄县漳江口、龙海市九龙江口、厦门市凤林湾、泉州市洛阳江口、宁德市湾坞5片红树林湿地的海洋线虫进行采样与优势属及摄食类型研究，主要研究结果如下:采样区域优势度大于等于5%的海洋线虫优势属依次为Sabatieria、Ptycholaimellus、Parasphaerolaimus、Terschellingia、Daptonema、Viscosia和Dichromadora，优势度依次为19.82%、7.88%、7.45%、7.26%、6.79%、6.00%和5.25%。在漳江口红树林、九龙江口红树林及洛阳江口红树林均以Sabatieria为第一优势属，优势度分别为27.87%、28.37%和23.40%；凤林红树林以Terschellingia为第一优势属，优势度为18.10%；湾坞红树林以Daptonema为第一优势属，优势度为22.86%。海洋线虫摄食类型数量的季节变化如下，漳江口红树林:1B>2A>2B>1A；九龙江口红树林:1B>2B>2A>1A；凤林红树林:1B>2A>2B>1A；洛阳江口红树林:2B>1B>2A>1A；湾坞红树林:2A>1B>2B>1A。在漳江口红树林、九龙江口红树林和凤林红树林中海洋线虫均以1B型为主导，在湾坞红树林中以2A型为主导，在洛阳江口红树林是2B型为主导，在5个区域内1A型海洋线虫的丰度均为最低。

| Abstract: | In April, July, October 2012, and January, April 2013, marine nematode dominant genera and feeding types were sampled for diversity analysis from five mangrove wetlands（Zhangjiang Estuary in Yunxiao Country, Jiulongjiang Estuary in Longhai City, Fenglin in Xiamen City, Luoyangjiang Estuary in Quanzhou City, Wanwu in Ningde City）in Fujian Province. It was found that the nematode dominant genera with dominance of percentages≥5% were Sabatieria, Ptycholaimellus, Parasphaerolaimus, Terschellingia, Daptonema, Viscosia and Dichromadora, which had dominance by 19.82%, 7.88%, 7.45%, 7.26%, 6.79 %, 6.00%, 5.25%, respectively. Sabatieria was the most predominant genus in the mangroves wetlands of Zhangjiang Estuary, Jiulongjiang Estuary and Luoyangjiang Estuary, with dominances are 27.87%, 28.37%, and 23.40%, respectively. Terschellingia was the most dominant genus in Fenglin mangrove wetlands, with a dominance of 18.10%. Daptonema was the most dominant genus in Wanwu mangrove wetlands, and dominance was 22.86%. The seasonal variations in abundance of their feeding types were as follows, in Zhangjiang Estuary wetlands, 1B>2A>2B>1A. In Jiulongjiang Estuary wetlands, 1B>2B>2A>1A. In Fenglin wetlands, 1B>2A>2B>1A. In Luoyangjiang Estuary wetlands, 2B>1B>2A>1A. In Wanwu wetlands, 2A>1B>2B>1A. Therefore, type 1B marine nematode showed to be the dominant in Zhangjiang Estuary, Jiulongjiang Estuary and Fenglin, type 2A was dominant in Wanwu wetlands, type 2B was dominant in Luoyangjiang Estuary wetlands, type 1A are the lowest in five regions. |
