南大洋是目前受人为活动干扰最少的区域,在平衡全球气候变化、维持生物多样性方面扮演了重要角色。由于其独特的自然条件和地理区位,各国学者自20世纪90年代起就开始对南大洋生态环境进行深入研究。为厘清全球范围内的南大洋生态环境研究现状、预测未来研究趋势,本文采用文献计量学的研究方法,统计了Web of Science核心数据库中已发表的南大洋生态环境相关研究论文,共获得有效论文7 491篇。基于VOSviewer软件分析了1990—2020年间关于南大洋生态环境的论文发表数量、发表机构、发表期刊、核心作者及主要研究主题,结果表明:(1)南大洋生态环境的相关研究逐年增加,1997年《京都议定书》的签订及其2005年的正式生效是南大洋生态环境研究数量明显上升的时间节点;(2)美国是南大洋生态环境研究的领军国家,拥有3个发文数量排名前十的科研机构;英国和澳大利亚也是南大洋生态环境研究的主要国家,其科研机构发文数量排名靠前;中国的南大洋生态环境研究起步较晚,目前仍处于追赶阶段,但与欧美国家的差距正逐步缩小;(3)30年间南大洋生态环境的主要研究领域包括“气候变化”“浮游植物”“南极磷虾种群”“海洋生... 相似文献

我国是遭受海洋灾害影响最为严重的国家之一,海洋防灾减灾不仅是我国也是全球重大议题。我国海洋灾害灾次频、灾种多、灾情重,直接危及人民生命财产安全,制约海洋经济长足发展并阻碍海洋生态文明建设。现阶段我国的海洋防灾减灾体系建设发展迅速,但与发达国家相比尚存差距。面对复杂严峻的形势,尤其是在机构改革的背景下,借鉴他国经验并健全完善我国海洋防灾减灾体系十分必要。因此,本文立足我国基本国情,选取具有丰富经验的日本作为比较研究对象,深入剖析中日两国现有海洋防灾减灾体系,在“一案三制”基本架构的视角下归纳两国差异,审视我国问题所在,并为我国未来海洋防灾减灾工作提出具有针对性的对策建议。 相似文献

Environmental management of military activities is of growing global concern by defence forces. As one of the largest landholders
in Australia, the Australian Defence Force (ADF) is increasingly concerned with sustainable environmental management. This
paper focuses on how the ADF is maintaining effective environmental management, especially in environmentally sensitive marine
protected areas. It uses Shoalwater Bay Training Area (SWBTA) as a research example to examine environmental management strategies
conducted by the ADF. SWBTA is one of the most significant Defence training areas in Australia, with a large number of single,
joint and combined military exercises conducted in the area. With its maritime component contained in the Great Barrier Reef
Marine Park (GBRMP), the Great Barrier Reef World Heritage Area (GBRWHA), and abutting Queensland’s State Marine Parks, it
has high protection values. It is therefore vital for the ADF to adopt environmentally responsible management while they are
conducting military activities. As to various tools employed to manage environmental performance, the ISO 14001 Environmental
Management System (EMS) is widely used by the ADF. This paper examines military activities and marine environmental management
within SWBTA, using the Talisman Saber (TS) exercise series as an example. These are extensive joint exercises conducted by
the ADF and the United States defence forces. The paper outlines relevant legislative framework and environmental policies,
analyses how the EMS operates in environmental management of military activities, and how military activities comply with
these regulations. It discusses the implementation of the ADF EMS, including risk reduction measures, environmental awareness
training, consultation and communication with stakeholders. A number of environmental management actions used in the TS exercises
are presented to demonstrate the EMS application. Our investigations to this point indicate that the ADF is complying with
all relevant legislation and policies. Further research is required to confirm compliance and conclude that military activities
have good accord with environmental management objectives. 相似文献

青岛市在海洋强国、海洋强省建设中拥有重要地位,切实提高海洋可持续发展能力、科学合理开发利用海洋资源是现阶段青岛市海洋工作的重点之一。在这一背景下,本文采用改良的DPSIR模型,从驱动力、压力、状态、影响、响应、改革的阻碍六个方面出发,构建了青岛市海洋资源可持续利用评价指标体系,利用熵值法确定了指标权重,并对2013年到2017年青岛市海洋资源可持续利用水平进行了分析。评价结果显示,青岛市海洋资源可持续利用水平在这几年间不断提高,呈现稳中向好的趋势。本文的结论将为青岛市相关政策的制定提供参考依据。 相似文献
