苏北废黄河口滨海港建设对近海水沙和床面冲淤的影响

以废黄河三角洲海岸盐城市滨海港的建设为背景,通过建立二维潮流泥沙数学模型,模拟建港前后水动力场环境与泥沙运移变化,分析滨海港建设对近海水沙的影响。南北堤建成后,流速变化主要集中在防波堤建设区域15 m等深线以内海域,变化量为−0.8～0.5 m/s。北堤堤头流速增幅明显,除大潮落急外港区均处在流速减小区,流速衰减幅度最高可达0.6 m/s。建港工程造成海域内潮汐不规则性减弱,主要分潮的平均振幅比降低约10%。建港工程对近海地貌格局的影响集中在港区周围8 km范围,且基本在16 m等深线以内海域,淤积区域分布在港区口门周围,冲刷区域分布在北堤堤头,床面变化随着时间推移加剧。     

Econometric analysis to differentiate effects of various ship safety inspections

This article provides a refined technique to measure and interpret variables associated with the quality of an inspection—be it port state control or vetting inspections towards the probability of a very serious, serious or less serious casualty. It concentrates on filtering out the effect of variables such as detention, the port state control regime that inspected the vessel, time in-between inspections, deficiencies found during an inspection and the effect of vetting inspections. The consensus amongst policy makers in the shipping industry is that data cannot be combined to target vessels. While this article does demonstrate that the decrease in the probability of casualty is stronger for the South American Region, the Indian Ocean Region and Australia versus North Europe, North America or the Caribbean, it also demonstrates that the data can be combined to target vessels for inspections. Since the time in-between inspections and detention is mostly not significant towards decreasing the probability of casualty, these results reflect the lack of coordination amongst port state control regimes and industry inspections. Due to this lack of coordination and trust, a ship might be inspected in several regimes during a relative short time period where the benefit of an inspection can be easily saturated. Our recommendation on direct policy implication is to promote the harmonization of inspection databases across port state control regimes, preferably with the coordination of the development of the Global Integrated Ship Information System (GISIS) of the International Maritime Organization (IMO), to review the policy of a release of a vessel from detention and to increase cooperation amongst regimes with respect to the follow up of the rectification of deficiencies.     

烟台港倾倒区表层沉积物重金属的富集特征及风险评价

分析了2001~2011年烟台港倾倒区表层沉积物中6种重金属的含量及时空分布特征,采用地累积指数(Igeo)和潜在生态风险指数(ERI)对重金属富集现状及潜在生态风险进行评价。结果显示：历次调查重金属含量均较低且空间分布差异小,与黄海背景值相比, Cd和Cu出现一定程度的富集。ERI评价表明2011年倾倒区潜在生态风险性较低,年际变化顺序为：2008年＞2006年＞2009年＞2011年＞2001年, Cd和Hg是近年来的主要风险因子。     

试论洋山深水港与上海国际航运中心建设

建设国际航运中心是上海城市发展的宏伟目标之一。目前,围绕东北亚国际航运中心的竞争十分激烈,釜山、神户、高雄等港口均提出了明确的发展目标,并纷纷建设一系列深水集装箱泊位。本文以国际竞争态势为背景,着重分析了国际集装箱航运市场的最新动态、洋山深水港对建设上海国际航运中心的重要意义,并详细论证了强化上海国际航运中心功能的政策创新,探讨了优化上海国际航运中心营运水平的关键措施,为推进上海国际航运中心建设献计献策。     

基于"一带一路"建设的环渤海地区港口优势评价

港口作为海陆运输的节点,是一个城市和国家的重要门户,对推动经济发展和对外贸易有着不可忽视的作用。基于国家提出的"一带一路"建设,评估环渤海港口的发展优势,逐步实现从沿海、沿江开放向内陆延伸具有重要意义。文章选取环渤海港口中的大连、天津、唐山、丹东、营口、锦州、秦皇岛、黄骅、日照、青岛、威海和烟台共12个港口进行发展优势对比。从港口吞吐量、港口规模范围、港口城市及腹地、港口未来发展4个方面构建环渤海港口优势评价体系。并利用熵权-TOPSIS法进行深入的实证分析。结果表明,环渤海港口群港口发展优势水平悬殊,基本可以分为4个档次。基于此,环渤海各港口应合理准确定位,通过错位发展和协同合作等方式谋求共赢。     

Dose of truth—Monitoring marine non-indigenous species to serve legislative requirements

Non-indigenous species (NIS) are recognized as a global threat to biodiversity and monitoring their presence and impacts is considered a prerequisite for marine environmental management and sustainable development. However, monitoring for NIS seldom takes place except for a few baseline surveys. With the goal of serving the requirements of the EU Marine Strategy Framework Directive and the EU Regulation on the prevention and management of the introduction and spread of invasive alien species, the paper highlights the importance of early detection of NIS in dispersal hubs for a rapid management response, and of long-term monitoring for tracking the effects of NIS within recipient ecosystems, including coastal systems especially vulnerable to introductions. The conceptual framework also demonstrates the need for port monitoring, which should serve the above mentioned requirements but also provide the required information for implementation of the International Convention for the Control and Management of Ships Ballast Water and Sediments. Large scale monitoring of native, cryptogenic and NIS in natural and man-made habitats will collectively lead to meeting international requirements. Cost-efficient rapid assessments of target species may provide timely information for managers and policy-advisers focusing on particular NIS at particular localities, but this cannot replace long-term monitoring. To support legislative requirements, collected data should be verified and stored in a publicly accessible and routinely updated database/information system. Public involvement should be encouraged as part of monitoring programs where feasible.
