海洋倾倒区封闭是海洋倾废管理的主要内容之一。目前疏浚物倾倒活动是一项比较频繁的海上倾倒活动。疏浚物海洋倾倒区的封闭，需要有一个相对统一的标准和判断方法，本文提出用外溢作为一种判断方法，且将倾倒 溢发为无外溢、少量外溢、显著外溢、严重外溢和最严重外溢五类，认为当倾倒区出现显著外溢时，应考虑限制使用；当倾倒区出现严重外溢时，考虑封闭；当出现危害性外溢时，就立即封闭。 相似文献

海上倾倒是疏浚物的主要处置方式,倾倒活动在一定程度上可引起海洋环境和局部海床变化,进而影响倾倒区的环境容量和倾倒容量。文章在倾倒区选划时倾倒容量计算方法的基础上,引入面积有效利用系数、可继续利用的水深等概念,通过分析倾倒区冲淤环境、流失率和倾倒区有效利用面积等,评估连云港２＃倾倒区使用期间的倾倒容量,探索使用过的倾倒区倾倒容量的评估方法。同时,分析海洋环境对倾倒强度和倾倒方式的响应情况,结合倾倒区使用期间海洋环境质量变化,评价倾倒容量的合理性,为海洋行政主管部门在倾倒区管理方面提供科学依据。 相似文献

The importance of marine spatial planning in advancing ecosystem-based sea use management 总被引：2，自引：1，他引：1
During the past 10 years, the evolution of marine spatial planning (MSP) and ocean zoning has become a crucial step in making ecosystem-based, sea use management a reality. The idea was initially stimulated by international and national interest in developing marine protected areas, e.g., the Great Barrier Reef Marine Park. More recent attention has been placed on managing the multiple use of marine space, especially in areas where conflicts among users and the environment are already clear, e.g., in the North Sea. Even more recent concern has focused on the need to conserve nature, especially ecologically and biologically sensitive areas, in the context of multi-use planning of ocean space. Despite academic discussions and the fact that some countries already have started implementation, the scope of MSP has not been clearly defined. Terms such as integrated management, marine spatial management, and ocean zoning are all used inconsistently. This is one of the reasons why its importance is not more seriously reflected at the levels of policy and decision-making in most countries. This article attempts to deal with this problem. It describes why MSP is an essential step to achieve ecosystem-based sea use management, how it can be defined and what its core objectives are. The article concludes with an analysis of the use and achievements of MSP worldwide, with particular focus on new approaches in Europe. 相似文献

Competing usage of marine space has prompted several coastal nations to implement marine spatial planning (MSP). While progressive governments promote the deployment of renewable energy technologies (RETs) in order to meet renewable energy capacity and greenhouse gas emissions reductions targets, offshore RETs become another player operating within a finite and already stressed marine environment. This paper applies the sectoral MSP process employed by Scotland to the Nova Scotia context in order to draft a MSP for the province's tidal energy sector. Applicable legislation is reviewed in order to establish the regulatory authorities with powers to plan for both the marine development and ecosystem protection agendas. The scoping process identifies suitable resource areas based on the operational parameters of commercially viable tidal current turbines (TCTs), while the sustainability appraisal identifies areas of cultural, industry, ecological, and socioeconomic constraint and exclusion. Plan option areas emanating from the applied methodology demonstrated a 238.345 km2 (98.1%) increase in suitable TCT deployment area than the marine renewable energy areas identified in Nova Scotia's Marine Renewable Energy Act which did not undertake such a methodology. 相似文献

Marine protected areas are promoted as a resource management tool for balancing ecological integrity with economic activity. However, MPAs frequently fail to achieve integrated, substantive outcomes. Participation failure is a common symptom of implementation failure. MPA experts often conclude that the remedy, in part, lies in better communication, with the implicit assumption that participation and communication are conjoined or synonymous. In this paper, the geography of communication in marine environments is analyzed as distinct from participation. It is argued that the logistical challenges of communicating in marine time and space must be taken into account beginning with the pre-implementation stage of an MPA; this requires recognition and analysis of the political nuances of whose space, whose time, and whose terms for communication. Research in Wakatobi National Park in Indonesia determined that marine managers and local communities have divergent experiences of participation, prompting three insights. First, the timing of public consultations must accommodate the variable rhythms of life in fishing communities in order to ensure broad representation. Second, co-presence in fishers’ space is critical for effective communication of marine knowledge and management strategies. Third, the deployment of ‘participation time’ by decision-makers communicates the value – or lack thereof – they place on fishing people and collaboration. The constructivist spatial analysis of communication presented here provides a model for MPA decision-makers and managers to identify, overcome and mobilize communication geographies that affect participation in sustainable development. 相似文献

Our global oceans are threatened by climate change, overfishing, pollution and a growing list of other impacts that demonstrate an urgent global need for sustainable ocean management. Whilst marine conservation initiatives and protected ocean spaces have increased over recent years, ocean management still lags behind the terrestrial sectors in incorporating and involving communities in its development. ‘Social licence to operate’ is used broadly across the terrestrial literature, but its understanding and application within the marine has been limited to date. This review sought to collate and synthesise instances of social licence in the marine realm as documented in the literature, aiming to create an understanding that may inform future research and development of social licence. Its results determine that social licence is yet an emergent concept in the marine sector but there may be great potential for its application in the marine context. Social licence has become an important theme for development in marine industry and resource use, particularly towards exploring communication and stakeholder engagement. This paper identifies future themes and areas requiring investigation and application in this domain. 相似文献
