从四个方面对现代海底热液活动输向大洋的热通量进行了初步估算.热液系统通过集中、高温的热液烟囱和低温、大面积漫溢热水的形式向海洋输送的热通量为357GW;由底热异常边界层计算出的热通量为32GW;根据Baker提出的扩张洋脊的扩张速率和扩张洋脊热液柱覆盖率之间的线性关系,推算的热液通量为1086GW;根据扩张洋脊岩墙冷却和扩张推算的热通量为592GW.不同的方法给出的结果有较大的差异.一方面这些结果反映了热液系统向大洋的供热水平,另一方面反映了目前对现代海底热液活动的认识水平.虽然热液系统向大洋的热输出比太阳的热辐射小,但由于其特殊的供热方式,这部分热能仍有可能对全球气候带来影响,应在今后的研究中给予重视.
The heat flux from the modern seafloor hydrothermal activity to the ocean has been preliminarily estimated from four aspects.Heat system transfers heat flux to the ocean through concentrated and hot hydrothermal chimneys and low temperature and large area of overflowing hot water Is 357GW. The heat flux calculated from the bottom thermal anomaly boundary layer is 32GW. According to the linear relationship between the expansion rate of dilatancy ridge and the coverage of thermal oceanic column on the extended oceanic ridge proposed by Baker, the calculated hydrothermal flux is 1086GW; The calculated heat flux is 592GW based on the cooling and expansion of the dilapidated dyke wall. The results obtained by different methods are quite different: on the one hand, these results reflect the level of heat supplied by the hydrothermal system to the ocean and the other Although the thermal output from the hydrothermal system to the oceans is smaller than the thermal radiation from the sun, this part of the thermal energy is still likely to bring about the global climate due to its special heating mode Influence, should pay attention to in the future research.
