| 摘 要： | 通过建立数学模型,分析了休渔措施下水生生物种群的动态.一年中生产积累大于捕捞积累时,种群持续生存;反之,种群趋向灭绝.休渔期越长,种群规模越大. |
| 关 键 词： | 休渔 模型 季节动态 周期解 |

| Abstract: | To investigate the effect of closed fishing,mathematical models were formulated and the aquatic organism population dynamics after closed fishing were analyzed.When producing accumulation is larger thanfi shing accumulation,the aquatic organismpo population persists,otherwise,the population dies out.Longer closed fishing season implies larger population size. |
| Keywords: | closed fishing model seasonal dynamics periodic solution |
