本文阐述了东亚海区海岸带综合管理实践如何从地方性的示范发展到区域性的合作管理框架，如何实现海洋和海岸带资源的可持续利用．文中着重突出了厦门市政府在维持环境保护和经济发展的平衡，启动和实施海岸带综合管理，以及与沿海国在国际合作方面的经验，总结了厦门实施海岸带综合管理的主要经验，包括多部门间综合协调机制、海岸带综合管理法律框架、科技支撑体系的建立，海洋功能区划、环境剖面和战略环境管理计划的制定，以及实现海上联合执法等等．同时阐述了东亚海域环境管理区域合作计划（PEMSEA）与澳大利亚合作伙伴之间的关系在推动沿海城市的国际合作中将起到的作用． 相似文献

海岸带综合管理被广泛认为是实现海岸带社会经济与生态环境可持续发展的重要途径之一.本文运用海岸带综合管理（ICM）的相关理论,结合厦门海岸带管理面临的实际问题, 在对厦门第一轮ICM执行情况进行充分回顾、评估的基础上,对厦门第二轮ICM面临的主要问题、涉及的优先领域及主要目标进行了分析研究;并在此基础上形成了厦门第二轮海岸带综合管理的战略行动计划. 相似文献

Xiamen Bay in South China has experienced extensive coastal exploitation since the 1950s,resulting in some severe environmental problems.Local authorities now have completed or are implementing many environmental restoration projects.Evaluating the cumulative impact of exploitation and restoration activities on the environment is a complicated multi-disciplinary problem.However,hydrodynamic changes in the bay caused by such coastal projects can be characterized directly and definitively through numerical modeling.This paper assesses the cumulative effect of coastal projects on the hydrodynamic setting using a high-resolution numerical modeling method that makes use of tidal current speeds and the tidal prism as two hydrodynamic indices.Changes in tidal velocity and the characteristics of the tidal prism show that hydrodynamic conditions have declined from 1938 to 2007 in the full-tide area.The tidal current speed and tidal prism have decreased by 40% in the western part of the bay and 20% in the eastern part of the bay.Because of the linear relationship between tidal prism and area,the degraded hydrodynamic conditions are anticipated to be restored to 1972 levels following the completion of current and proposed restoration projects,i.e.33% and 15% decrease in the hydrodynamic conditions of 1938 for the western and eastern parts of the bay,respectively.The results indicate that hydrodynamic conditions can be restored to some extent with the implementation of a sustainable coastal development plan,although a full reversal of conditions is not possible.To fully assess the environmental changes in a region,more indices,e.g.,water quality and ecosystem parameters,should be considered in future evaluations. 相似文献
