| 摘 要： | 头足类是最具开发潜力的渔业种群之一，然而其资源易受环境变化影响，复杂的交互作用致使二者空间关系呈现非均一性。中国枪乌贼 (Uroteuthis chinensis) 是南海北部近海重要的经济物种，且在渔业群落结构中占据优势种地位，故正确理解与掌握该物种资源-环境关系的空间特征，有助于该资源的保护与利用。基于南海北部近海2014年夏季的渔业资源调查数据，构建了地理权重回归模型 (Geographical weighted regression, GWR)，探索该海域中国枪乌贼的资源分布与海洋环境关系的空间特征，阐述主要影响因子。模型评价指标结果表明，GWR的最小赤池信息准则 (Akaike Information Criterion, AIC) 和校正决定系数 (Adjusted R-Squared,

| Abstract: | Cephalopods are one of the most potienial fishery species but are vulnerable to environment changes, and their complex interactions lead to the spatial heterogeneity in resource-environment relationship. Uroteuthis chinensis is an important economic species in the offshore waters of northern South China Sea, occuping a dominant position in the fishery community structure. Therefore, understanding the spatial characteristics of the resource-environment relationship is beneficial to its development, utilization and protection. Based on the fishery resources survey data in the offshore waters of northern South China Sea in summer of 2014, we established a geographically weighted regression (GWR) model to explore the spatial characteristics of the relationship between the resource distribution of U. chinensis and the marine environment in this area, and to reveal the main influencing factors. The results of model evaluation indexes show that the minimum Akaike information criterion (AIC) and adjusted R-Square (
