In this paper, the research of ocean biogeochemistry of nitric oxide is introduced , including the NO production of ocean and phytoplankton , and the elationship between the nitric oxide and the phytoplankton.

摘 要：介绍了 NO 海洋生物地球化学的研究现状，包括海水和浮游植物的 NO 来源和 NO 对浮游植物生长影响的研究概况，并对今后 NO 的研究提出了若干想法。

He proved that the left ward turning of Yangtze river diluted water is mainly resulted from the interaction between the bottom declining and the lag of the transversal pressure gradient, made the numerical simulation and preliminary study on the thermohaline staircase structure formation mechanism, improved American Academician Wunsch's inverse method of ocean circulation, jointed the discover of " Mindanao Under Current", which is the first ocean current found and named by Chinese scientists and widely accepted over the world, simulated the horizontal and vertical carbon fluxes in East China Sea by a simple ecosystem model, estimated the photosynthesis efficiency less than 8% in Jiaozhou Bay, applied statistical downscaling technology to Chinese coast and Japanese islands realizing the simulation and forecast of sea level low frequency variations, pointed out that the quasi-periodicity of El Nino events should be resulted from the interaction between the 3~4 year oscillation in tropical Pacific and decadal oscillation in the northern Pacific of middle latitudes of the air-sea coupled climate system and at decadal time scale the precipitation influence on sea level variation along Chinese coast and Japanese islands becomes more important, which is closely related to the decadal oscillation of air-sea coupled climate system, therefore precipitation most likely play a major role for the decadal oscillation formation;; proposed Extended Associate Pattern Analysis to analyse combined observed datasets of sea surface temperature and sea level pressure or geopotential hight at 1000 hPa (GH1000) over the Pacific and related seas.

论证了长江冲淡水向左转向主要由于底形下倾与横向压力梯度滞后相互作用的结果。对温盐阶梯结构的形成过程及物理机制进行了数值模拟与初步探讨。改进了美国科学院院士Wunsch的大洋环流反演法。与胡敦欣院士共同发现了"棉兰老潜流"，这是第一支由中国科学家发现、命名并得到普遍承认的洋流。借助较为简单的生态模式数值模拟了东海的水平与垂直碳通量；胶州湾浮游植物的屏蔽效应可以使底层海水温度在升温季节降低2度，由此推算出其光合作用的效率应小于8%；浮游植物春季水华的生物过程实际上强化了海水层化的物理过程。将统计学降尺度技术应用于日本列岛和我国沿海，实现了海平面长周期变化的模拟与预报。

The main results are as follows: 1. From the specimens we observed 5 phyla 53 genus 106 species of phytoplankton. The mean density and biomass of phytoplankton are 80.954xl04 ind/L and 0.567 mg/L.

结果如下： 1。样品中共检出浮游植物5门53属106种，浮游植物的平均密度和生物量分别为80.954×10~4 ind／L和0.567 mg／L。

In total, 5 phyla, including 72 genera and 177 species were identified, of which chain\|shaped ones were dominant, in which diatoms dominated, and dinoflagellates went the second place.

共鉴定出浮游植物5门72属177种，浮游植物以硅藻为主，但甲藻在群落中的比重也很明显，此外还有少量的绿藻、蓝藻和金藻。

Pelagic tunicates are an important group of zooplankton in the subtropic and tropic waters. Distribution and variation of their species richness and abundance are influenced by physical and biological factors. Pelagic tunicates play an important role in marine food web carbon cycle as they feed on bacterioplankton and pico-and nano-phytoplankton and meanwhile are preys for commercial animals.

浮游被囊动物是热带和亚热带海域重要的浮游动物类群，种类和数量的分布变化受物理和生物环境因素的影响；它一方面大量摄食浮游细菌和微小浮游植物，另一方面被一些经济动物摄食，因此在海洋食物链的传递和生态系统的物质循环中占有重要位置。

The results show that the contents and distributions of mercury in Jiaozhou Bay were affected by coastal runoff and phytoplankton bloom The linear relationship between organic mercurv and the COD and the exponential relationship between inorganic mercury and chl-a implied that marine phytoplankton could absorpt mercury in sea water and played an important role in controling the speciations of mercury in the Bay.

测定结果表明，胶州湾中汞含量和分布规律与浮游植物的盛衰和陆地迳流有关。有机汞和COD之间存在着线性关系，溶解无机汞含量随叶绿素a含量增加呈指数下降，表明浮游植物对汞的富集及其在海水中形态的转化起着十分重要的作用。

Of the total 262 species found in this area, 82 occurred in spring, 117 in summer, 119 in autumn, and 141 in winter. Taxonomically, 252 species in 67 genera were Bacillariophyta, 8 species 5 genera were Pyrrophyta and 2 species 1 genus were Cyanophyta.

中文摘要：2006 年8 月—2007 年4 月对广东省徐闻珊瑚礁区的浮游植物进行了周年的季节调查，结果共检出浮游植物262 种：春季82 种、夏季117 种、秋季119 种、冬季141 种，其中硅藻门67 属252 种，甲藻门5 属8种，蓝藻门1 属2 种。

Results show that there are 73 species,62 genus,8 phylum phytoplankton,which is mainly composed of the Chlorophyta ,Bacillariophyta and Cyanophyta.

2005年12月和2006年6月对苏州平原河网区57个浅水湖泊的浮游植物群落进行了调查，共检出浮游植物8门62属73种，浮游植物主要由绿藻、硅藻和蓝藻组成。

From Chaotianmen to Zigui,the Shannon-Weaver diversity index of phytoplankton changes undeely.4 the impact of sediment deposition on zooplankton in the waters studiedAccording to the results of the experiment, we had learnt that the species composition of zooplankton sampled had the same tendence-the species was from less to more, and the biomass was also gradually increasing. Particularly Copepoda had increased significantly in the type and quantity. The main of zooplankton at each sampling situs were protozoa and rotifers.

朝天门江段到秭归江段的浮游植物的Shannon-Weaver多样性指数呈波浪式变化，整体有下降趋势。4研究水域泥沙沉降对浮游动物的影响从本次实验的结果来看，四次采样浮游动物种类组成都有同一个趋势：种类由少到多，生物量也逐渐增大，特别是桡足类在种类和数量上都增加明显，各采样点的浮游动物以原生动物和轮虫为主。
