辽东湾海蜇资源衰退仿真研究

Simulate of the depletion of fishery and jellyfish in Liaodong Bay

运用Netlogo仿真工具对辽东湾海蜇资源进行仿真实验,探讨海蜇资源可持续利用的途径.研究结论表明:大规模的海蜇增殖放流可以有效缓解短期内无法大幅度降低捕捞强度和海域污染的压力,但不能从根本上遏制海蜇资源的衰退.海域污染和捕捞强度是实现系统优化的关键,两者的降低是一个渐进过程,首先,可以采取增加海蜇资源初始量代替降低海域污染水平和捕捞强度的措施;其次,是以降低海域污染水平和捕捞强度为主的分阶段海蜇捕捞专项管理措施.

Based on Netlogo software ,this paper simulates the jellyfish resources of Liaodong Bay to explore the way of how to sustain the jellyfish resources .The results show that the fishing intensity and sea pollution are the key factors of system optimization ,which are effective ways to restore and sustain the jellyfish resources for decreasing fishing intensity and sea pollution .It is also a gradual process .T he result indicates that breeding massively babies of jellyfish may take the place of decrea‐sing fishing intensity and sea pollution .Therefore ,the government should adopt two steps .The first is breeding massively babies of jellyfish to replace decreasing fishing intensity and sea pollution .T he second is decreasing fishing intensity and sea pollution .
