【摘要】 运用回归分析和主成分分析方法，研究Johnson&Raven(1973)给出的加拉帕戈斯群岛29个岛屿的物种数据以及地理环境数据，建立岛屿物种数据与地理环境数据的回归模型.研究结果表明，加拉帕戈斯群岛各岛屿的物种数量与岛屿海拔高度、岛屿最临近岛屿面积、岛屿面积与最临近岛屿面积之比等因素显著相关，与岛屿的其他周边环境因素关系不显著，并给出了对相关结论的地理学和生物学解释，揭示了经典论文数据中蕴含的新信息.更多还原

【Abstract】 This paper employs regression analysis and principal component analysis to study the species data and geographical environmental data of the 29 islands in the Galápagos Archipelago as provided by Johnson & Raven(1973). Regression models were developed to explore the relationship between species data and geographical environmental factors. The research findings reveal that the number of species on each island in the Galápagos Archipelago is significantly correlated with factors such as island elevation, the area of adjacent islands, and the ratio of island area to the area of adjacent islands, whereas no significant correlation was observed with other environmental factors. Geographical and biological interpretations of these findings are discussed, uncovering new insights present in the data from the classic paper.更多还原
