气候变化对长江口鱼类资源密度分布的重塑作用

本研究以2012-2013年长江口鱼类资源密度分布为基础,通过动态生物气候分室模型（DBEM）预估了不同气候变化情景下（IPCC,RCP2.6、RCP6.0和RCP8.5）长江口鱼类资源密度增量分布的变化。在RCP2.6、RCP6.0和RCPS.5这3种气候变化情景下,鱼类资源密度增量、底层鱼类资源密度增量随着时间推移均呈递增趋势,且递增程度和增量重心分布范围随着温室气体排放的增加而扩大（RCP8.5〉RCP6.0〉RCP2.6）。鱼类资源密度增量重心主要分布在长江口崇明岛沿岸水域,长江口外侧水域资源密度增量相对较低,并且资源密度增量重心有向南迁移的趋势。...

Climate change affects the distribution of fish species and thus alters the pattern of fish abundance. However, effects of climate change on China coastal fisheries have not been studied yet. Estuaries play an important role in the function of marine ecosystem, hence they are key habitats for many fishery species and form ideal fishing grounds. Here we investigated the impacts of climate change on fish abundance by estimating the distribution of dominant an
