We develop an index that is a measure of the intensity of marine activities in large marine ecosystems (LMEs). We compare this marine activity index with an index of socioeconomic development across ocean regions. This comparison identifies regions that may be capable of achieving the sustainable development of their regional marine environment on their own and those that are less likely to do so. The latter may be candidates for international financial or management assistance. An important next step is to carry out detailed case studies designed to improve our understanding of any specific ocean region. 相似文献

海洋渔业对海洋生态系统的影响越来越受到人们的重视,考虑生态系统的管理已经成为海洋渔业管理的发展趋势.作者分析了海洋渔业对海洋生态系统产生的影响,包括捕捞活动对目标和非目标种产生的危害、渔业资源栖息地和环境破坏、生物多样性降低等;分析了国际上考虑生态系统的海洋渔业管理的法律框架、国际组织和有关国家的实践及其具体措施,指出了中国在此方面存在的问题:海洋生态系统的基础科学研究缺乏系统性和全面性;基于生态系统的海洋渔业管理的理论研究比较缺乏;相关的法律框架不够完善等.讨论了应用生态系统方法的海洋渔业管理与传统的海洋渔业管理间的关系,指出生态系统方法在其实践中将存在各种问题,认为生态系统方法应有选择地应用.对中国海洋渔业管理如何应用生态系统方法,建议:(1)加强海洋生态系统的基础科学研究;(2)开展基于生态系统的海洋渔业管理理论和方法研究;(3)逐步建立相关的法律和制度框架;(4)开展广泛的多部门合作和国际合作. 相似文献

Essential ecological insights for marine ecosystem-based management and marine spatial planning 总被引：4，自引：2，他引：2
The abrupt decline in the sea's capacity to provide crucial ecosystem services requires a new ecosystem-based approach for maintaining and recovering biodiversity and integrity. Ecosystems are places, so marine spatial planners and managers must understand the heterogeneity of biological communities and their key components (especially apex predators and structure-forming species), and of key processes (e.g., population connectivity, interaction webs, biogeochemistry) that maintain them, as well as heterogeneity of human uses. Maintaining resistance and resilience to stressors is crucial. Because marine populations and ecosystems exhibit complex system behaviors, managers cannot safely assume they will recover when stressors are reduced, so prevention is a far more robust management strategy than seeking a cure for degraded systems. 相似文献
