| 摘要: |
| 基于大量实验结果和大规模海上考察和综合分析, 从基础生物学和生态学的角度, 对中国近海水母暴发的机理提出一种新的理论模式: 水母生活史中的大部分时间以水螅体的形式生活在海底; 水母种群的暴发是水螅体对环境变异的一种应激反应, 是为了逃避动荡环境、扩大分布范围、寻求新的生存空间, 为种群繁衍需求更多的机会的一种生存策略。导致水母种群暴发的关键过程是海洋底层温度的变动和饵料数量的变化, 全球气候变化和富营养化是中国近海水母暴发的最重要诱发因素。水母暴发是全球变化下海洋生态系统演变的一种综合体现。 |

| Abstract: |
| The results of the experiments in laboratory and cruises in the Chinese coastal waters and continental shelf area showed that the jellyfish bloom occurred in the East China Sea and Yellow Sea was caused by bottom sea water temperature turbulence and the rich food supply. The hypothesis is that the jellyfish usually live on the sea bottom as the form of polyps as benthos, when the environment temperature under the turbulent condition, it will trigger the polyps asexual reproduction to the strobilation, producing ephyra. This process is the way for jellyfish to escape from the crisis environment, wander in the sea water to settle in the new environment and find new opportunities for live by coincidence. The key factors for the jellyfish bloom are temperature stimulation and food supply. Climate change and eutrophication are the main causes of the jellyfish bloom in the Chinese coastal waters. |
