摘要: 基于2016年11月(秋季)和2017年4月(春季)在玉环北部沿岸海域渔业调查所获的数据资料,运用相对重要性指数(IRI)、生态位宽度、生态位重叠、方差比率法、X2 检验、联结系数(AC)、Jaccard指数(JI)、点相关系数(Φ)和Spearman秩相关系数等方法对主要游泳动物物种间的生态位和种间联结性进行研究.结果表明: 三疣梭子蟹的生态位宽度值最大,占绝对竞争优势;重要经济种类刀鲚与长蛸的生态位宽度值最小,处于弱势竞争地位.该海域主要游泳动物生态位重叠程度不均匀,可能是由于生活环境多样化所致.总体联结性分析表明,本海域物种之间呈不显著负关联. X2检验、ACJI结果均与总体联结性的结果一致且物种之间趋于独立.Φ和Spearman秩相关系数的结果显示,正联结的种对多于负联结的种对,可能是由于所捕获的大个体海鳗对其他物种产生空间排斥,使得其余14个物种组成的种对间多呈现正联结所致.根据Spearman秩相关系数计算结果,采用聚类分析方法将15个物种分为5个生态种组:同一生态种组内,各物种对生境具有相似的生态适应性要求;不同生态种组的物种之间则具有不同的生活习性和不同的生态要求.

Abstract: Base on the data from fishery resources survey carried out in northern coastal waters in Yuhuan in November 2016 (autumn) and April 2017 (spring), we examined the niche and interspecific associations of major nekton by the methods of index of relative importance (IRI), niche breadth, niche overlap, the variance ratio (VR), X2-test, association coefficient (AC), Jaccard index (JI), point correlation coefficient (Φ) and Spearman rank correlation index. The ecological niche breadth of Portunus trituberculatus was the largest, with the absolute competitive advantage. The niche breadths of the important economic species Coilia nasus and Octopus variabilis were the smallest, which was at a weak competitive position. The niche overlap of the major nekton species in this area was uneven, possibly caused by the diversity of local environments. Overall interspecific associations indicated that insignificant negative correlation existed among major nekton species. All results of the X2-test, association coefficient (AC) and Jaccard index (JI) were consistent with that of overall interspecific associations, which indicated the independent trend among species. The correlation coefficients (Φ) and the Spearman rank correlation index revealed that the positive coupling pairs were more than the negative ones. It was due to the positive association among the other 14 species, caused by the spatial exclusion from large captured individuals of Muraenesox cinereus. According to the Spearman rank correlation and cluster analysis, 15 species could be divided into five ecological groups. The species within one ecological group had similar ecologically adaptable requirements of habitat, while the species from different ecological groups had different living habits and different ecological requirements.
