宁波商帮的海洋文化情结

宁波商帮是我国十大商帮之一 ,百年经久不衰 ,究其原因是宁波商帮受到独特的宁波城市文化熏陶。宁波得天独厚的海洋优势 ,造就了有悠久历史凝结和中外文化交融的宁波海洋文化。海洋文化是一种先进的文化 ,具有大海的许多秉性 :大度、创新、包容。宁波城市文化把中国传统的儒家文化和宁波海洋文化很好地结合起来。正是这种独特的宁波城市文化 ,才哺育出顽强开拓、勇于创新 ,克勤克俭、脚踏实地 ,注重团队、和衷共济的“宁波商帮精神”。     

Statistical analysis of surface hydrography and circulation variations in northern South China Sea

1 INTRODUCTIONThe South China Sea (SCS) is a semi-enclosedmarginal sea in western North Pacific Ocean withvery complex topography and is the important pas-sage connecting the Pacific and Indian Oceans. Ithas great impact to the global climate and a greatinterest of many oceanography researchers. Twodominant surface hydrographic and circulation fea-tures in the northern SCS are a strong fresh waterexpansion and a warm and high-salinity seawaterintrusion such as the SCS Diluted Water…     

修武:千年古坑免遭一劫

近日,修武县国土资源局西村国土所及时制止一起盗采铁矿石行为,使该乡一"千年古坑"免遭破坏. 被当地人称为"千年古坑"的大水坑位于修武县北部山区西村乡黑岩村与孟泉村交界处,呈椭园形,长约50米,宽约30米,最深处约4米.此坑是自然形成,坑里的水是靠雨季和雪融水储存的.千百年来,黑岩和孟泉两村千余口人和牲畜就是靠吃这个水坑里的水生存的,坑里的水常年清澈见底,不用过滤不用沉淀可直接饮用.随着经济的发展,山区饮水条件的改善,此坑里的水现已成为黑岩村的牲畜饮用水.在上世纪70年代,黑岩村村民对坑内进行了清於,对已损坏的护坑石楞进行了维修,并作为历史古迹保护了下来.

Mantle processes during ocean formation：Petrologic records in peridotites from the Alpine－Apennine ophiolites

Mantle peridotites were early exposed at the sea-floor of the Jurassic Tethys derived from the subcontinental mantle of the Europe-Adria system. During continental rifting and oceanic spreading, these lithospheric peri-dotites were percolated via diffuse reactive porous flowby melt fractions produced by near-fractional melting of the upwelling asthenosphere. Ascending melts inter-acted with the lower lithosphere, dissolving pyroxenes and precipitating olivine, and crystallized at shallower levels in the mantle column causing melt impregnation.Subsequent focused porous flow formed replacive dunitechannels, cutting the impregnated oeridotites, which were conduits for upward migration of MORB-type liq-uids. Melt migration produced depletionlrefertilization and significant heating of the percolatedlimpregnated mantle, i.e the thermochemical erosion of the litho-sphere. Impregnated and thermally modified lithos-pheric mantle was cooled by conductive heat loss dur-ing progressive lithosphere thinning and was intrudeaby MORB magmas, which formed Mg-rich and Fe-richgabbroic dykes and bodies. Alpine-Apennine ophiolitic peridotites record the deep-seated migration of melts which changed their compositions and dynamics during the rift evolution. The thermochemical erosion of the lithospheric mantle by the ascending asthenospheric melts, which induces significant compositional and rhe-ological changes in the lower lithosphere, is a major process in the evolution of the continent-ocean transi-tion towards a slow spreading oceanic system.

赤潮

严格来讲,赤潮是一种自然现象。《圣经》中记载的河水变红、《聊斋志异》里提到的河水发光,或许是民间对赤潮类事件最古朴也最形象的记录。1831～1836年达尔文乘“Beagle”号环球航行时也对赤潮做过相关记录,虽然那时尚无人提出明确的“赤潮”概念。近几十年来由于对人类的娱乐及生产活动影响越来越严重,频繁发生的赤潮逐渐被界定为环境污染及海洋灾害的一种。河里的水都变作血了。河里的鱼死了,河也腥臭了,埃及人就不能吃这河里的水,埃及遍地都有了血。——《旧约·出埃及记》众坐舟中,旋见青火如灯状,突出水面,随水浮游;渐近舡,则火顿灭…     

澳门附近海域沉积物污染状况及特征分析

掌握澳门附近海域沉积物的污染状况及特征,对于合理安排澳门海洋海岸工程疏浚泥的海洋倾倒,防止造成海洋污染有十分重要的意义。根据1997—1999年连续三年对澳门附近主要区域的海洋沉积物采样测定结果,通过分析认为澳门附近海域沉积物污染具有下列特征:1)沉积物中重金属和油类含量普遍较高,除了总Hg外均高于珠江口海区的其他港口;2)沉积物中污染物的分布受人类活动的影响明显,澳门内港受船只排污、码头作业、陆地工业和生活污水排放的影响,是澳门附近海域沉积物污染最为严重区域;3)受水质交换的影响明显,澳门外港、路环岛东北等区域受珠江径流影响水质交换较快,沉积物中污染物的含量较低,而内港由于水质交换较差,沉积物中污染物的含量相对较高;4)与沉积物的成分组成(吸附)有关,大部分污染物与沉积物中粉砂有较好的相关性,表明粉砂对污染物质有较广泛性的吸附能力,尤其是Cu、Zn、Cd、油类、有机质。
