福建省海洋工程装备产业现状与发展对策探讨

近年来,福建海洋工程装备产业进步显著,初步形成了以港口装卸、海上起重机、海底铺管、大型汽车滚装船等传统装备为主导的制造基地;同时,海水淡化核心装备、海洋防腐材料、水下作业机器人、游艇装备等新兴产业也取得了快速发展,但仍存在产业基础薄弱、整体产品低端、研发力量小且分散、试验研发平台严重不足等制约"瓶颈"。文章通过现场调研和资料查询分析了福建海洋工程装备产业的发展现状,总结归纳出当前制约产业发展的主要因素,明确发展思路,提出建设具有海西特色的海工装备制造业应发展海洋工程装备的重点领域、编制福建省海洋工程装备中长期发展规划和实施方案、提升海洋工程装备科技创新能力、制定海洋工程装备发展的扶持政策、构建比较完整的重点领域海洋工程装备产业链等对策与建议。     

农村信用社产权制度创新研究

现行农村信用社存在的出资人所有权虚置、收益权削弱、法人财产权丧失等产权制度缺陷 ,严重阻碍着它的进一步发展。形成这些缺陷的主要原因在于农村信用社产权改革的方向不明和对产权范畴的片面理解 ,因此 ,农村信用社产权制度创新应在清晰界定产权的基础上、向股份制、股份合作制、合作制等多种产权形式的方向发展。

Fishing industry and related perspectives on the issues raised by no-take marine protected area proposals

In the face of growing calls for no-take marine protected areas (NTMPAs), the views of fishing industry representatives in south-west (SW) England on related issues are analysed. Only 23% thought NTMPAs were the way forward and a range of concerns were expressed, e.g. that the ‘terrestrial’ protected areas approach and related biodiversity conservation objectives will be extended to the seas, and that fish yield reductions from the loss of access to NTMPAs are very unlikely to be compensated for through spillover/export. Some interesting approaches to ameliorating these concerns emerged, such as being open and honest that NTMPAs are primarily intended to achieve biodiversity conservation benefits, reducing uncertainty concerning the potential for any secondary fisheries spillover/export benefits, justifying NTMPAs on an objective, rational basis rather than on a subjective, precautionary basis, and the quid pro quo streamlining of wider fisheries management approaches. This research reveals a more diverse range of perspectives amongst fishing industry representatives on the issues raised by NTMPA proposals than is often assumed.     

Decoupling of stalagmite-derived Asian summer monsoon records from North Atlantic temperature change during marine oxygen isotope stage 5d

The Asian monsoon is an important component of the global climate system. Seasonal variations in wind, rainfall, and temperature associated with the Asian monsoon systems affect a vast expanse of tropical and subtropical Asia. Speleothem-derived summer monsoon variation in East Asia was previously found to be closely associated with millennial-scale change in temperature in the North Atlantic region between 75 and 10 ka. New evidence recovered from East Asia, however, suggests that the teleconnection between summer monsoon in East Asia and temperature change in the North Atlantic region may have significantly reduced during 120 to ~ 110 ka, a period directly after the full last interglaciation and corresponding roughly to marine oxygen isotope stage 5d. This reduction may be due to the low ice volume in the North Hemisphere at that time, which makes the millennial-scale change in temperature in the North Atlantic region less effective in influencing the Asian summer monsoon. This is important for investigating the mechanisms controlling the Asian summer monsoon and the paleoclimatic teleconnection between East Asia and the North Atlantic region, and for predicting monsoon-associated precipitation in East Asia under a global-warming trend.     

UV-B辐射对海洋微藻抗氧化系统的影响

研究了UV－B辐射对两种海洋微藻－小新月菱形藻（Ntzschia closterlum)和亚心形扁藻（Platymonas subcordiforming)的抗氧化系统的影响。结果表明：在本实验的辐射剂量范围内，随着UV－B辐射剂量的增强，两种藻的抗氧化防御系统的非酶性组分还原型谷胱甘肽（GSH）和类胡萝卜素（CAR）的含量随之下降；抗氧化防御系统的酶性组分超氧化歧化酶（SOD）和过氧化氢酶（CAT）的活性逐渐降低。加入外源性抗氧化剂GSH可减轻UV－B辐射对藻的伤害。分析表明海洋微藻的UV－B伤害是由于抗氧化防御系统遭到破坏而导致活性氧积累的结果。     

环球海洋大气气溶胶化学研究

1986年11月—1987年5月,在中国第三次南极考察和环球科学考察期间,收集了58个海洋气溶胶样品,采用中子活化法分析了Al,V,Mn,I,Br,Mg,Na,Cl等元素。应用因子分析、回归分析和富集因子分析对气溶胶中元素进行分类、定量评估和来源判别,讨论不同来源元素的特征,计算各主要来源的贡献分量。结果表明,海洋气溶胶中Al的99.99％是来自陆源地壳风化物,Na的99.2％。和Cl的99.99％是来自海水,V的91.4％。来自陆源污染物。因此,Al可作为海洋气溶胶中陆源地壳风化物的示踪元素,Na和Cl可作为海水源示踪元素,非地壳源的V则可选择为陆源污染物的示踪元素。     

The role of marine spatial planning in sea use management: The Belgian case

The expansion of offshore activities and the increasing need to meet international and national commitments to biodiversity conservation have led to an enhanced interest in marine spatial planning (MSP) as a tool for sea use management. Several European countries, on their own initiative or driven by European legislation and policy, have taken global leadership in implementing MSP. This article will discuss the Belgian experiences with MSP. It will give a short historical overview based on legal developments and review the implementation process of a ‘Master Plan’ as a spatial management policy for the Belgian Part of the North Sea. Additionally, this article will reflect on the research that has been done in Belgium to apply a land-use planning approach to the marine environment. The MSP process in Belgium shows that a spatial approach to sea use management is possible despite the lack of a legal zoning framework. However, it concludes that a legal basis for MSP, in addition to the current permit system, would provide a more strategic and integrated framework for ecosystem-based, sea use management.

Developing a Marine Information System by Integrating Existing Ocean Models Using Object-Oriented Technology

Information systems developed for different applications within the environmental domain have common characteristics, which can potentially be abstracted for sharing and reuse of design and software modules. This article presents an approach to designing for reuse by abstracting commonalities in the design of a Marine Information System (MIS), facilitating data management in a prototype operational monitoring, forecasting, and management system for the North Atlantic and the Nordic Seas. A detailed study of the requirements and data analysis was carried out, and Object-Oriented Technology (OOT) is employed to encapsulate abstractions and to promote reuse of code and design. This article identifies the Object-Oriented Frameworks (OOFW) required to build the MIS. It also provides guidelines to environmental scientists for restructuring legacy software and employing modern programming techniques.
