因子分析是分析存在于多个变量之间关系的一种多元统计分析方法。通过因子分析可以从大量的观测数据中提取出少数有代表性的因子,进而用这些因子来说明多变量数据所提供的信息。因子分析以往多数是用于研究地质、古生物、陆地动植物以及海洋浮游生物的系统分类上。用这种方法研究海洋鱼类数量分布关系,笔者至今尚未查阅到有关的文献。 根据试捕调查~(**),胶洲湾水域是多种鱼类交替进行生殖、摄食和发育的场所,胶洲湾的环境受潮流、河口影响较大。鱼种类繁多,数量分布比较复杂。
Factor analysis is a multivariate statistical analysis that analyzes the relationship between multiple variables. Through factor analysis, a small number of representative factors can be extracted from a large number of observations, and these factors can be used to illustrate the information provided by multivariate data. Most of the factor analysis used to study the system of geology, paleontology, terrestrial flora and fauna, and marine plankton. Using this method to study the relationship between the distribution of marine fish numbers, the author has not yet access to the relevant literature. According to the pilot catch survey (**), Jiaozhou Bay waters are places where many species of fish alternate for reproduction, feeding and development. The environment of Jiaozhou Bay is affected by the tidal current and the estuary is more influential. A wide range of fish, the number of distribution is more complicated.
