Analysis on Marine Science and Technology Strategy and Key Layout of Japan and the Inspirations to China

The Basic Ocean Law (BOL) and Basic Ocean Plan (BLP) are important guarantee for the maritime strategy of Japan, which has established a complete policy system for the development of marine science and technology. On the other hand, the Japanese Government has started some major marine strategies and plans to promote the BLP. In this paper, the marine science and technology plans launched by the Japanese Government and its participation in the international cooperative research projects were introduced. The research of Japan Marine Science and Technology Center and the University of Tokyo Institute of Oceanography in the long-term planning and focus on the layout features, deep sea research technology layout, contents and advanced equipment were analyzed. At last, some recommendations for China’s development on marine science and technology were proposed, such as strengthening the legislation work and process, carrying out research and development of marine infrastructure with independent intellectual property rights, actively participating in international large-scale ocean plan, improving the discourse right and enhancing national maritime awareness and suggestions and so on.

基于第二代测序技术的条斑紫菜(Pyropia yezoensis)贝壳丝状体附生菌群研究

条斑紫菜(Pyropia yezoensis)贝壳丝状体黄斑病给育苗产业造成危害,但目前对健康状态下的菌群结构及其发病后变化仍缺乏认识。本研究基于第二代测序技术和16S r RNA序列分析,对健康和患病丝状体的细菌组成与变化进行比较。测序共产生1.6Gb配对末端序列,获得了第一个高通量的条斑紫菜贝壳丝状体细菌群落数据集。通过数据分析共识别出7,833种可操作分类单元(operational taxonomic units,OTUs),比对确定为18个细菌门。相对于健康样本,黄斑病丝状体样本的微生物多样性显著增加。主坐标分析和非加权组平均法(unweighted pair group method using arithmetic average,UPGMA)聚类均将健康和黄斑病丝状体分成不同的组,且健康组样本间的距离明显小于黄斑病组。上述结果说明,健康贝壳丝状体保持着相似的微生物群落结构,而患病后的丝状体则发生了不同的变化;健康样本和黄斑病样本组间差异显著的细菌属有39个,其中29个在健康样本中的相对丰度明显高于病患组样本。本研究从菌群生态角度分析了健康贝壳丝状体微生物菌群结构、发病后菌群的变化及其对丝状体生长的潜在作用,为丝状体病害的检测和预防提供有价值的信息。     

Marine science and technology transfer: Can the Intergovernmental Oceanographic Commission advance governance of biodiversity beyond national jurisdiction?

Marine scientific research is crucial to forge solutions in the development of a new international legally binding instrument for the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction (ABNJ) under the 1982 United Nations Convention on the Law of the Sea . The transfer of marine technology, capacity development and marine genetic resources are key issues. This paper examines how the Intergovernmental Oceanographic Commission (IOC), as a competent international organisation for marine scientific research and technology transfer, can inform the development of the instrument. Synergies between marine technology transfer and non-monetary benefit sharing of genetic resources are illustrated. Four key lessons from the IOC are examined: 1. Coordinating international cooperation in marine scientific research; 2. Enabling open access to data and knowledge; 3. Facilitating capacity development through scientific training and education; and 4. Governance of marine scientific research. Realising the potential of the IOC to advance governance solutions for ABNJ will depend on increased political will from Member States and strengthened partnerships to reduce resource constraints and enhance the IOC's capacity at global and regional scales.     

反渗透海水淡化技术现状和展望

反渗透膜技术于20世纪60年代取得突破性进展,促使反渗透海水淡化在近50年间高速发展,淡化产能自20世纪90年代起激增.海水反渗透(SWRO)淡化已成为目前投资最省、成本最低的利用海水制备饮用水的过程.文中主要对海水反渗透淡化的发展状况进行了介绍,如膜和组件的改进,关键设备高压泵和能量回收装置效率的提高,多种工艺过程的不断发展,包括预处理和后处理的新工艺,以及对环境的影响和相应对策等.反渗透技术的发展也推动了其他膜分离技术的进步,并扩展其应用领域.预计在不久的将来,膜技术在海水淡化和水再利用、扩大和保护水资源、循环经济、清洁生产、改造传统产业、节能减排及提高人民生活水平等方面发挥的作用会越来越显著.
