基于生态系统的海洋管理理论与实践

海洋孕育了丰富的生态系统服务功能,包括为人类提供多种海产食物、净化海洋环境和提供宜人景观及发展空间等。随着工程科技水平的提高,人类对海洋资源和空间的开发利用越来越多、越来越快,对海洋生态系统的影响也越来越大,这一问题在我国尤为突出。近20年来一些发达国家通过推行基于生态系统的海洋管理(MEBM),在海洋生态系统的框架下规范和管理开发活动,特别是在解决区域性海洋管理问题方面取得了一定成效,值得我们借鉴。概述了海洋生态系统及其服务功能,回顾了海洋开发中存在的问题以及MEBM的发展历程,系统阐述了MEBM的原则和措施,剖析了国内外MEBM的成功案例,探讨了在中国实施MEBM的必要性和前提条件。近年来,我国依据海洋功能区划来管理海洋开发已取得一定的成果。建议以此为基础,强化相关生态科学研究及相应技术和法规支撑,从而为我国海洋经济可持续发展提供保障。

Theory and Practice for Marine Ecosystem-Based Management

The ocean entails mankind a vast reserve of ecosystem services, providing rich seafood, clean environment, pleasant scenery, space for development and so forth. In recent years, advances in engineering practices and technologies have enabled exploitation of the ocean on a large scale and at a faster pace, resulting in deleterious impacts on the ocean and coastal ecosystems; which is clearly reflected in China’s case. Over the last twenty years, a number of countries have implemented Marine Ecosystem-Based Management (MEBM), by supervising and governing development activities under the framework of marine ecosystems, which has obtained promising results, especially in coping with regional governance issues. China can learn much from these beneficial experiences in dealing with its marine ecosystem problems encountered today. In this paper, the characteristics and functions of the marine ecosystems are summarized, and ecosystem problems encountered globally and nationally in marine development along with the evolution of MEBM are briefly reviewed. Next, the principles and measures for MEBM are elucidated in details, successful MEBM practices at home and abroad are analyzed, and the necessity and precondition for implementing MEBM in China are discussed. China’s progress, together with its drawbacks, in recent years in governing ocean development based on the National Marine Functional Zoning is then discussed. Finally, to ensure sustainable development of China’s marine economy, we propese to enhance ecological science studies, invest in eco friendly technologies, and strengthen relevant laws and regulations in support of MEBM.
