In this study, the bacterial community structures in samples of ballast water collected from a ship from Singapore and of local sea water collected from Xiamen Port were compared using restriction fragment length polymorphism (RFLP) and 16S rDNA sequence analysis. Except for dominant a-Proteobacteria that are common to both systems, the bacterial community structures of the two systems were quite different. Most of the clones derived from the different systems were grouped into different phylogenetic clusters, and the systems share only one common RFLP pattern. The ballast water, which is likely from clean offshore waters, contains sequences specific to aand c-Proteobacteria. Phylogenetic analysis revealed that the ballast water contained sequences belonging to attached bacteria and bacteria commonly found in the open sea, as well as many novel sequences. In addition, no known pathogenic bacteria were detected in the ballast water samples. Conversely, water samples from Xiamen Port were apparently affected by the near shore environments. Specifically, in addition to aand c-Proteobacteria, water from Xiamen Port contained band d-Proteobacteria, Synechococcus, Bacteroidetes and Actinobacteria, which are common in coastal environments. Additionally, four pathogenic bacterial sequences and one plasmid sequence of a potential red tide forming alga were detected in the water from Xiamen Port, which suggests that the local sea water is polluted. The results of this study can be used as background information to assess the risk associated with the introduction of non-indigenous species to local systems and to establish ballast water management systems.

The variability of the sea surface temperature（SST） in the china seas has been studied in seasonal,interannual and interdecadal scales based on the monthly data of HadISST spanning from 1870 to 2007. The main results obtained are SST in the china offshore changes most actively at the seasonal scale with the intensity diminishing from north to south,as the temperature differences between summer and winter reaching 17 and 4 C in the northern and southern areas,respectively. Moreover,seasonal variation near the coastal regions seems relatively stronger than that far from the coastline;significant interannual variations are detected,with the largest positive anomaly occurring in 1998 in the overall area. But as far as different domains are concerned,there exists great diversity,and the difference is also found between winter and summer. Differed from the seasonal variations,where the strongest interannual variability takes place,resides to the south of that of the seasonal ones in the northern section,nevertheless in the South china Sea,the most significant interannual variability is found in the deep basin;interdecadal changes of summer,winter and annual mean SST in different domains likewise present various features. In addition,a common dominant warming in recent 20 a are found in the overall china offshore with the strongest center located in the vicinity of the Changjiang Estuary in the East china Sea,which intensifies as high as 1.3 C during the past 130 a.

A two-dimensional numerical model is constructed to study the interaction between the coastal upwelling and the coastal front off Zhejiang coast in summer. In the f-plane model, the shelf topography, continuous stratification, and Richardson number-dependent eddy coefficients are considered. The results show that the coastal up-welling off Zhejiang in summer can be divided into two regions, the nearshore one (Region A) and the offshore one (Region B). In Region A, the alongshore wind stress has more important effect on the coastal upwelling while in Region B, the upwelling is mainly induced by the Taiwan Warm Current. The results also suggest that the formation of coastal front off Zhejiang in summer is closely related to the strength of the coastal upwelling in Region A.

滨海盐沼及其植物群落的分布与多样性

滨海盐沼是广泛存在于世界中、高纬度地区的一种湿地生态系统,具有抵御风暴潮灾害、净化污染物和为珍稀濒危生物提供适宜生境等重要的生态和经济价值。滨海盐沼因随高程变化而急剧变化的环境梯度和植物带状分布现象而为生态学者阐释自然界物种的分布机制提供了理想系统。主要概述了滨海盐沼的定义、特点、类型、全球分布以及潮汐作用、土壤盐度等环境因子特征;阐述了不同尺度下滨海盐沼的植物群落分布和多样性特征。在滨海盐沼植物群落的分布特征上,重点阐述了中尺度下的植物带状分布,即植物群落往往在自海向陆渐高的不同高程梯度上表现出显著的分带分布,不同植物各自占据该梯度上的一定区域。通常认为,带状分布是植物竞争和物理性胁迫共同调控的结果,但其在不同地理区域的普适性仍存争议。滨海植物群落多样性往往较低,在中、小尺度上盐沼植物多样性受控于盐度、潮汐等物理性胁迫、植物间相互作用等因子的作用;在大尺度上盐沼植物多样性可能随纬度增大而增加。系统深入地认识滨海盐沼植物群落生态格局和过程,将为气候变化、生物入侵等人类影响下的滨海盐沼生态系统的管理和恢复提供有益经验。

依据1842～1997年10幅不同年代的长江口海图资料,利用地理信息系统和数字化仪进行处理,建立不同时期的长江口水下数字高程模型,以此作为基础资料,实现了从横剖面、深泓线纵剖面、平面变化等不同角度对长江口拦门沙地区滩槽演变、岸线侵蚀、沙岛形成与变迁等进行研究.通过计算河槽容积,实现了对不同时段泥沙冲淤量的计算.结果表明,155a来拦门沙总的趋势是不断淤积,但不同时期淤积速度大不一样,个别时期甚至会发生一定程度的冲刷,这主要与动力条件的波动有关.1842～1997年,共淤积泥沙38.10亿t,平均每年淤积 0.246亿t,约占长江来沙的5％,年均淤厚为1.1cm 泥沙淤积部位主要在九段沙、横沙及横沙东滩、崇明东滩三处.发生冲刷的范围较小,仅占总面积的21.4％,主要在北槽,北港上段和南槽局部也有轻微的冲刷发生.
