摘要:

在全球气候变化的大背景下, 物种分布格局的变迁已成为科学界关注的焦点。文章依据政府间气候变化专门委员会 (Intergovernmental Panel on Climate Change, IPCC)关于全球气候变化的分析, 运用最大熵模型(maximum entropy, MaxEnt)与地理信息系统(geographic information system, GIS)技术, 对中国沿海的带鱼(Trichiurus japonicus)在不同共享社会经济路径(shared socioeconomic pathways, SSPs)情景下的潜在适生区分布进行深入分析, 识别了影响其分布的关键环境因素, 并预测了在不同SSPs情景下带鱼未来栖息地的变化趋势。研究数据基于全球生物多样性信息机构(Global Biodiversity Information Facility, GBIF)和世界鱼类数据库(Fishbase)提供的70个有效物种分布记录, 以及海洋生物气候与环境分析栅格数据库(Biological Ocean Rasters for Analyses of Climate and Environment, Bio-ORACLE)提供的13个海洋环境变量。模型的准确度通过受试者工作特征曲线(receiver operating characteristic, ROC)进行验证, 模型的平均曲线下面积(area under the curve, AUC)值为0.913, 表明模型具有出色的预测性能。研究发现, 带鱼在我国四大海域均有适宜的栖息地, 其中中高适宜分布区占总预测区域的11.96%; 温度、叶绿素浓度和初级生产力是影响带鱼分布的关键环境因素, 且底层环境变量的贡献普遍高于表层环境变量; 预测未来随着气候变化, 带鱼的适生区总体呈现扩大趋势, 在SSP5-8.5情景下扩张最为显著, 主要表现为向黄渤海等高纬度区域扩展, 而在南海北部湾等低纬度区域则有所收缩。

Abstract:

This study predicted the potential distribution of Trichiurus japonicus along China’s coastal waters under the influence of global climate change, using the maximum entropy (MaxEnt) model integrated with Geographic Information System (GIS) techniques. Species occurrence data (70 valid points) were obtained from Global Biodiversity Information Facility (GBIF) and FishBase, while environmental variables were sourced from Bio-ORACLE. Model performance was evaluated using the Receiver Operating Characteristic (ROC) curve, yielding a high accuracy (0.913) of Area Under the Curve (AUC). Our results indicated that suitable habitats for T. japonicus are distributed across China’s four major marine regions, with medium-to-high suitability areas accounting for 11.96% of the total predicted area. Temperature, chlorophyll concentration, and primary productivity were identified as key environmental factors affecting hairtail distribution. Model projections under different shared socioeconomic pathway (SSP) scenarios suggested an expansion of suitable habitats with a potential northward shift towards the Yellow Sea and Bohai Sea, while contracting in the waters of South China such as Beibu Gulf in the future.

Key words: Trichiurus japonicus, MaxEnt model, marine environmental factors, potential habitat, global climate change
