加强CEPA框架下的粤港澳海洋事业合作

海洋经济在粤、港、澳经济中具有十分重要的地位,港、澳回归以后,三地海洋事业合作的内在需求得到充分表达。CEPA破除地方贸易保护和改进贸易合作创造了新机遇。建议以8个重点领域的海洋合作作为CEPA扩展的内容。     

情系港珠澳大桥

正10月24日,超级跨海工程、世界最长的跨海大桥——港珠澳大桥历经14年筹建,正式开通。它跨越伶仃洋,东接香港、西接广东珠海和澳门,总长约55千米,是粤港澳三地首次合作共建的超大型跨海交通工程;它实现总体跨度最长、钢结构桥体最长、海底沉管隧道隧道最长,也是公路建设史上,技术最复杂、施工难度最高、工程规模最庞大的桥梁。人们欣喜地注视着这颗伶仃洋上的明珠时,作为大桥建设的参与者,我深感自豪和欣慰。港珠澳大桥的正式开通,把我的思绪带回到十年前的日日夜夜……     

全国省（区）界线全部勘定

自1996年开始的全国大勘界即将完成。除港、澳、台外，其余68条省、区界线全部勘定，其总长63000km的实勘结果，比原来数据增加很多。     

海洋经济研究生教育的兴起与发展

人们对海洋的探索以及对海洋经济的认识和研究,促使海洋经济(专业)教育的兴起。20世纪80年代初期,与"海洋经济"相近方向的研究生教育开始;新世纪以来,明确设立"海洋经济"研究方向的研究生教育得到较快发展。必须积极解决海洋经济的学科性质及其归属、发展定位等限制研究生教育的问题,有关海洋经济科研院所和高校必须大力合作,促进海洋经济学科及其研究生教育的大发展。     

蔚蓝色：中华文明的再度辉煌

在数千年的历史长河中，中华民族既有因亲近海洋，在航运及船舶制造、海上贸易、海洋渔业等方面谱写下了壮丽的篇章，创造出了灿烂的海洋文明的辉煌时期，也有过因疏远海洋、丧失了世界文明领先地位，沦为“东亚病夫”而遭受任人崭割的悲惨岁月。回顾过去，展望未来，开发海洋、经略海洋，必将带来中华文明的再度辉煌。     

白海豚跃出水面红树林遍布湿地 ——粤港澳携手推动大湾区生态文明建设

<正>穿行在港珠澳大桥上,如果足够幸运,可以看到野生中华白海豚跃出水面,与大桥上的"海豚"造型钢塔相映成趣。9年时间,这座连接粤港澳三地的钢铁巨龙在伶仃洋上凌空而起,其建造过程竟实现了中华白海豚"零伤亡"和生态环境"零污染"。作为粤港澳大湾区建设的重大基础设施,港珠澳大桥犹如大湾区建设的注脚,清晰传递了生态文明之于大湾区的意义。     

借海洋文化之风扬泛北部湾经济合作之帆

随着中国-东盟博览会永久落户广西南宁,北部湾(广西)经济区建设逐步升温,泛北部湾经济合作日益紧密,古老的北部湾广西沿海地区迎来了现代海洋文明的曙光,获得了大发展的历史性机遇.相信借助海洋文化与海洋经济的成功互动,将广西沿海建设成为新的一极,必将有力地推动泛北部湾经济合作,支撑起北部湾(广西)经济区的可持续发展.     

论海洋文化及其与海洋经济的关系

从哲学的角度，探讨了海洋文化的概念和构成，论述了海洋经济和海洋文化的关系。同时指出，正确处理海洋经济和海洋文化的关系，对发展海洋经济具有重要意义。     

海洋自然资源国民经济评价体系的探讨

海洋开发主体在开发利用海洋自然资源时，往往会产生负的外部性，所以在对项目中费用和效益识别的基础上应加强海洋开发项目的国民经济评价，其中采用的主要经济指标有经济净现值、经济净现值率、经济内部收益率、经济外汇净现值和经济换汇成本。     

博弈论视域长三角港口群双港口合作策略稳定性研究

构建演化博弈模型情景化模拟长三角港口群双港口间合作效益的稳定性以判别长三角港口群竞合关系趋向合作的临界条件。研究表明:(1)长三角海洋岸线类型总体呈现以南通市为分界点的空间格局,且目前长三角港口群合作形成以上海港和宁波―舟山港为核心的两条合作主线;(2)长三角港口群中港口合作策略稳定性受价格敏感度差异性的影响,呈现稳定性、不稳定性以及阶段性稳定的3种情景,且随着选择合作策略港口数量的增加,该比例最终会趋向稳定于某一水平;(3)港口高层管理者在选择策略时应考虑其他港口价格策略变动对自身策略的影响,共同优化长三角港口群演化方向。     

Thermohaline structure inhomogeneity associated with polynia at the northern margin of Emery Ice-shelf

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area.     

Phylogenetic analysis of cultivable bacteria isolated from Arctic sea-ice

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter.

Relationship of Arctic sea ice and Northern Hemispheric 500 hPa Polar vortices

Using the NCEP/NCAR reanalysis monthly 500 hPa height data on a 2.5 latitude-longitude grid and 1°×1° sea ice data,the polar vortex area,intensity index and arctic sea ice area index are calculated respectively,and the meridional distribution,period variation and the abrupts in the long range trend are analyzed to study their relationship.The results show that the meridional distribution of sea ice and polar vortex h-ave distinctive difference,the relative positions of them are different in the eastern and western hemispheres,and exept they have periods of 4 months,quasi half year,quasi year,4-5 years and 10 years commonly,and each of them has its own respective variation as well.The sea ice area is decreasing apparently since 1980's,so is the polar vortex area,but their abrupt changge time are different totally.The area of sea ice and polar vortex has prominent positive correlation,but the relationship of sea ice intensity,polar vortex intensity,polar vortex area is complicated.     

Preliminary study on plasma membrane fluidity of Psychrophilic Yeast Rhodotorula sp.NJ298 in low temperature

The ability of cell to modulate the fluidity of plasma membrane was crucial to the survival of microorganism at low temperature. Plasma membrane proteins, fatty acids and carotenoids profiles of Antarctic psychrophilc yeast Rhodotorula sp. NJ298 were investigated at -3 ℃, 0 ℃ and 8 ℃. The results showed that plasma membrane protein content was greater at -3 ℃ than that at 8 ℃, and a unique membrane polypeptide composition with an apparent molecular mass of 94.7 kDa was newly synthesized with SDS-PAGE analysis; GC analysis showed that the main changes of fatty acids were the percentage of unsaturated fatty acids (C18∶ 1 and C18∶ 2) and shorter chain saturated fatty acid (C10∶ 0) increased along with the decrease of the culture temperature from 8 ℃ to -3 ℃; HPLC analysis indicated that astaxanthin was the major functional carotenoids of the plasma membrane, percentage of which increased from 54.6±1.5% at 8 ℃ to 81.9±2.1% at -3 ℃. However the fluidity of plasma membrane which was determined by measuring fluorescence anisotropy was similar at -3 ℃, 0 ℃ and 8 ℃. Hence these changes in plasma membrane's characteristics were involved in the cellular cold-adaptation by which NJ298 could maintain normal plasma membrane fluidity at near-freezing temperature.
