| Research Abstract |
1) Mechanisms of the destruction of benthic ecosystem
In the condition of high temperature and low DO, Musculista Senhousia (MS) was killed then the DO consumption of the corpse of MS was measured. The results show the DO consumption is denoted by exponential function, and the DO consumption rate is three times higher respiration rate and the rate becomes higher with the temperature.
2) Mechanisms of the sustainability of destructed benthic ec0system
The model which describe the mechanisms that the acceleration of DO consumption by corpse of MS causes enlargement oxygen deficit water. The simulations based on the model, show better agreement with the results which were collected by the survey on the Hakata bay.
