| 摘 要： | 基于沿浦湾2014年10月(秋季)和2016年10月(秋季)的潮间带大型底栖动物调查资料,运用生态位宽度、生态位重叠、功能群分类和冗余分析(RDA)等指标与方法,分析秋茄(Kandelia candel)种植前、后大型底栖动物的生态位、功能群变化。研究结果表明,秋茄种植后广生态位种和中生态位种物种数占比与种植前相比较均有所增加,窄生态位种物种数占比减少。种植前生态位重叠值最大的种对为大青弹涂鱼(Scartelaosgigas)和细螯虾(Leptochela gracilis)(0.94),种植后则分别为豆形拳蟹(Pyrhila pisum)和微黄镰玉螺(Lunatica gilva)(0.99)、堇拟沼螺(Assiminea violacea)和光滑河篮蛤(Potamocorbula laevis)(0.99)。种植后高、中潮带功能群多样性较种植前上升,而低潮带功能群多样性下降;种植后浮游生物食者(Pl)、植食者(Ph)和杂食者(Om)的密度较种植前均增加,而肉食者(Ca)的密度略有减少。秋茄种植前3个潮带之间无显著性差异(P0.05);秋茄种植后高潮带与低潮带,以及中潮带与低潮带均有显著性差异(P0.05)。冗余分析(RDA)得出,对大型底栖动物群落具有较大影响的因子由种植前的铅、镉和石油类变为种植后的锌、镉和砷。总之,苍南沿浦湾秋茄林种植对大型底栖动物生态位和功能群总体上具有积极的改善作用。

| Abstract: | Based on data from the macrozoobenthos resource survey along Yanpu Bay in October 2014 (autumn) and October 2016 (autumn), variation in the ecological niche and functional groups following planting of Kandelia candel were studied via niche breadth, niche overlap, functional group classification, and redundancy analysis (RDA). The results showed that the proportions of the wild niche and middle niche species increased after planting whereas that of the narrow niche species decreased. The species pair comprising Scartelaos gigas and Cambarellus shufeldtii (0.94) presented the highest niche overlap before planting, whereas those of Pyrhila pisum and Lunatica gilva (0.99), and Assiminea violacea and Potamocorbula laevis (0.99) were highest after planting. Compared with the diversity index of the functional groups before planting, the diversity index of the functional groups in high and middle tidal zones was increased whereas that in low tidal zones was reduced after planting. Densities of the planktophagous group (Pl), phytophagous group (Ph), and omnivorous group (Om) increased whereas that of the carnivorous group (Ca) decreased slightly compared with the year before planting. There were significant differences (P<0.05) between the high and low tide zones, as well as the middle and low tide zones after planting; however, the relationships between each pair of intertidal zones were not significantly different (P>0.05) before planting. The RDA concluded that the factors with greater effects in macrozoobenthos communities changed from lead, cadmium, and petroleum before planting to zinc, cadmium, and arsenic after planting. In summary, planting Kandelia candel along Yanpu Bay had a positive effect on the overall improvement of the ecological niche and functional groups of macrozoobenthos. |
