摘　　要：本文根据2016-2017年在长山列岛邻近海域开展的渔业资源和环境季度调查数据,利用两阶段广义可加模型分析了该海域褐牙鲆资源丰度的时空分布及其与相关因子之间的关系。结果表明,长山列岛邻近海域褐牙鲆资源丰度具有明显的季节变化,春、秋季资源丰度高于冬、夏季;褐牙鲆春、秋季主要分布在120.5°~122.5°E水域,夏、冬季则向外海适宜水温水域移动;褐牙鲆出现概率主要受季节、底层盐度和底层水温的影响,在盐度31左右时出现概率较大;褐牙鲆相对资源量大小主要受底层盐度及水深影响,在水深33 m上下相对资源量较大。长山列岛邻近水域褐牙鲆资源丰度具有明显时空异质性,受到多重因素的共同影响。According to the seasonal fishery resource survey data from 2016 to 2017 in the adjacent waters of Changshan Islands, two-stage generalized additive model is used to examine the spatio-temporal distribution of Paralichthys olivaceus abundance and its relationships with relevant factors. The results show that the abundance of P. olivaceus exhibites obvious seasonal variation, and the abundances in spring and autumn is higher than those in winter and summer. In spring and autumn, it mainly distributes in the waters of 120.5°-122.5°E;and in summer and winter, it moves to the waters with suitable water temperature. The occurrence probability of P. olivacvacus is mainly affected by season, bottom salinity and bottom temperature. The probability of occurrence is relatively high at the salinity of 31. The relative abundance of P. olivaceus are mainly affected by bottom salinity and depth, and the relative resources is higher at the depth of 33 m. The spatio-temporal heterogeneity of the abundance distribution of P. olivaceus is affected by multiple factors in the adjacent waters of Changshan Islands.
