摘要/Abstract

摘要： 根据2001年秋季东海区121个调查站位的调查资料，以变异函数为工具，分析带鱼和7种小型鱼类(黄鲫、棘头梅童鱼、鳄齿鱼、六丝钝尾-虎鱼、发光鲷、七星底灯鱼和细条天竺鲷)的空间异质性及其空间关系.结果表明，带鱼的变异函数曲线与细条天竺鲷、六丝钝尾-虎鱼和发光鲷的曲线极为相似，对不同距离的变异函数值进行相关分析，带鱼与上述3种小型鱼类均达到极显著相关水平(P<0.01).黄鲫和棘头梅童鱼的变异函数表现出纯金块效应，而其它几种鱼都可拟合为球状或指数模型，并且都具有较强的空间自相关特性，其中细条天竺鲷、六丝钝尾-虎鱼和发光鲷的变程也都接近或超过带鱼265 km的变程，带鱼与这3种小型鱼类之间具有较强的空间追随关系，因此它们是带鱼的主要摄食对象.

Abstract: Based on the investigation at 121 positions in East China Sea in 2001 Autumn, this paper analyzed the spatial heterogeneity of hairtail (Trichiurus japonicus) and seven kinds of small-scale fish (Setipinna taty,Collichthys lucidus,Champsodon capensis,Amblychaeturichthys hexanema,Acropoma japonicum,Benthosema pterotum andApogon lineatus),and the spatial relationships among them.The results indicated that the semivariogram curve of hairtail was very similar to those of Apogon lineatus,Amblychaeturichthys hexanema and Acropoma japonicum,with highly significant correlations (P<0.01),and the semivariograms of Setipinna taty and Collichthys lucidus appeared as pure nugget effect.The others could be described as spherical or exponential model that had high spatial autocorrelation.The ranges of Apogon lineatus,Amblychaeturichthys hexanema and Acropoma japonicum were equal to or beyond that of hairtail (265 km).Hairtail was spatially close to these three species,and thus,the latter might be the main preys of hairtail.
