中文摘要： 该项目通过对北部湾海洋生态环境，资源等信息进行采集、处理、存储，建立了北部湾海洋生态环境本底数据库系统。建立数学模型模拟北部湾海洋生态及资源管理，通过对模型的动力学行为（包括系统的边界平衡点,内部平衡点，周期解的存在性,唯一性，稳定性,持久性,分支,混沌吸引子等等）进行研究，重点开展了以下三方面的研究：北部湾海洋环境保护专题研究（侧重于海洋污染的研究；毒素与疾病对海洋生态系统的影响研究；营养物质和污染物共同对海洋生态系统的影响研究）；北部湾资源保护、开发与利用专题研究（侧重于海洋保护区下海洋生态-经济模型研究；年龄阶段结构模型的研究；不同迁移率下开发模型研究）；北部湾海洋动植物病虫害的综合治理专题研究（侧重于海洋噬菌体感染研究；红树林生物病虫害的防治研究；具有非线性感染率的模型研究；收获对水产养殖疾病控制的影响研究）等等。为北部湾的海洋经济可持续发展提供技术支持和决策依据，进而为地方政府制定海岸带和海洋生态环境、海洋资源开发利用的政策和措施提供科学的决策依据，使广西北部湾海洋获得可持续性的开发利用与保护。同时，依托该项目，加强了团队建设，培养了一批青年教师，形成了一个比较稳定的研究团队

英文摘要： This project has obtained the background database about Beibu Gulf marine ecology environmrnt and resources by sampling, data processing and storing. Biomathematical models are set up to simulate the marine ecology environment and resourrces managing. Dynamic behaviors are shown such as the existence and uniqueness of boundary equibrium, interior equilibrium or periodic solution, stability, pemarnence, bifurcation and chaos etc. The project focuses on the following researches in three aspects about Beibu Gulf: Firstly, marine ecology environment protection which contains marine pollution, toxicant and disease, joint effects of nutrients and contaminants etc. Secondly, protection, exploitation and using for marine resources which contain marine ecological-economic models with reserves, age-structured models, exploiting models with different diffusing rate etc. Lastly, integrated prevention and management for marine ecological infectious disease which contains marine bacteriophage infection, the integrated pest managemnet for mangrove, the infectious models with nonlinear incedence rate, harvesting as a control measure for aquaculture disease etc. The results obtained from this research provide technical support and decision making basis for sustainable development of marine economy of Beibu Gulf, further it is good for local government to set policy and take measures about the development and utilization of coastal zone, marine ecological environment and marine resources exploitation so as to make a sustainable development and protection for Guangxi Beibu Gulf Ocean. On the other hand, based on this project, the research team building is enhanced and a group of young teachers are cultivated so that a stable research team is formed.
