| 机械刺激所致生物发光无论对于海洋生态学的研究还是对于水下目标探测均具有重要意义。本研究利用现场测量数据，首次定量化揭示了夏季黄渤海机械刺激所致生物发光强度的三维空间分布特征，并在此基础上，进一步结合同步测量的环境参数及浮游植物种群数据分析了其影响因素。主要结论包括：（1）夏季黄渤海机械刺激所致生物发光强度较强，其平均值约为4×1010photons/（s·L），最大值约为2×1012photons/（s·L），高值区主要出现在长江口附近海域；（2）夏季黄渤海机械刺激所致生物发光的物种以甲藻类浮游植物为主，在甲藻中，夜光藻对机械刺激所致生物发光强度的分布起着主要决定作用；（3）夏季黄渤海机械刺激所致生物发光的空间分布对温度、盐度及以叶绿素浓度为代表的总生物量的整体依赖性较低。 |

| Abstract: |
| Bioluminescence, as a striking phenomenon, is ubiquitous throughout the China seas. In this study, we used quantitative field data to demonstrate the mechanical-stimulated bioluminescence potential (MBP) distribution characteristics and to analyze its driving factors using simultaneously measured environmental variables and phytoplankton species data. The results show that first, the intensity of summertime MBP was very high in the Yellow Sea and Bohai Sea, on average of 4×1010photons/(s·L) in maximum of 2×1012photons/(s·L), and was particularly high in the regions adjacent to the Changjiang (Yangtze) River estuary. Secondly, the intensity distribution of summertime MBP in the Yellow Sea and Bohai Sea was mainly dominated by dinoflagellates, in which Noctiluca scintillans played the main role in controlling the distribution pattern of the MBP. Thirdly, MBP was weakly related to the environmental variables and the total biomass. |
