台湾海峡及其邻近海域中华哲水蚤的分布和繁殖

中华哲水蚤(Calanus sinicus Brodsky)是我国近海的优势桡足类。它的数量大，分布广。特别在冬、春季，在我国近海浮游动物中，占有相当大的比例；同时它的个体也较大，是滤食性种类。因其在海洋生态系统的物质循环和能量流动中，起着相当的作用，所以被国家自然科学基金重大项目-“东、黄海生态系统动力学与生物资源可持续利用”课题定为浮游动物的关键种之一。 作者根据以往历史资料(方金钏，1979；朱长寿，1997；朱长寿等，1991、1999；林玉辉等，1988；林元烧等，1984；李少菁，1963；陈清潮，1964；福建省海岸带和海凃综合调查领导小组，1990；福建海洋研究所，1988；Tan，1970)和多年来的研究结果(黄加祺等，1984，1986a、b、c，1989，1991a、b，1997a、b)，对中华哲水蚤在不同水域的分布，与温、盐度关系及繁殖进行了探讨，并提出见解，为本项目子课题提供了历史资料。     

福建红树林上钻孔动物的生态

福建红树林上的钻孔动物共发现了５种，其中软体动物的龙骨节铠船蛆Ｂａｎｋｉａ ｃａｒｉｎａｔａ、裂铠船蛆Ｔｅｒｅｄｏ ｍａｎｎｉ和甲壳动物的光背团水虱Ｓｐｈａｅｒｏｍａ ｒｅｔｒｏｌａｅｖｉｓ是破坏红树林的主要的钻孔动物。钻孔动物钻凿红树茎的基部和裸露的根部，垂直分布受潮汐水位制约，在红树林区的纵深分布与水流畅通程度有关。     

虾夷扇贝人工诱导雌核发育精子遗传失活及紫外线照射对精子形态结构影响的研究

在1698μWcm-2s^-1的紫外线照射强度下，虾夷扇贝雌核单倍体的最佳诱导时间为60s。从早期胚胎存活率可以观察到Hertwig效应的存在。随着照射时间增加，受精率明显下降，而受精卵在到达D形幼虫期之前便停止发育。扫描电镜显示，随着紫外线照射强度的增加。精子顶体和鞭毛结构趋向于受到更大程度的破坏，直到完全失去顶体和鞭毛。并指出这可能是造成受精率降低的主要原因。     

海岸带专题地图编绘相关问题

海岸带是影响人类活动的重要地带，海岸带专题地图能够详细表示出海岸带的特性。随着海洋经济的发展，海岸图的需求日益增加。从地图的数学要素出发，提出目前海岸图绘制存在的问题，并从地图学、海洋学、遥感地学的角度，对地图投影的选择、坐标系转换、比例尺对海岸图编绘的影响及控制点的确定等问题进行了综合分析。

Sublittoral meiofauna with particular reference to nematodes in the southern Yellow Sea, China

Densities of major meiofaunal taxa were investigated at 34 sampling stations during six cruises by R/V Beidou to the southern Yellow Sea, China from 2000 to 2004, and the community structure of free-living marine nematodes was studied during one of the cruises in 2003. Meiofauna abundance ranged from 487.4 to 1655.3 individuals per 10 cm². Nematodes and harpacticoid copepods were the two most dominant groups, contributing 73.8–92.8% and 3.5–18.7%, respectively, to the total meiofauna abundance. One-way ANOVA showed no significant annual fluctuation of meiofauna and nematode abundances from 2000 to 2004 in the southern Yellow Sea. However, two-way ANOVA based on six stations sampled in 4 years (2001–2004) showed that there were significant differences among the six stations and the 4 sampling years for meiofauna, nematode and copepod abundance. Correlation analysis demonstrated that meiofauna abundance was mainly linked to chloroplastic pigments. Other environmental factors could not be ruled out, however. A total of 232 free-living marine nematode species, belonging to 149 genera, 35 families and 4 orders, were identified. The dominant species in the sampling area were the following: Dorylaimopsis rabalaisi, Microlaimus sp.1, Prochromadorella sp., Promonohystera sp., Cobbia sp.1, Daptonema sp.1, Leptolaimus sp.1, Halalaimus sp.2, Aegialoalaimus sp., Chromadorita sp., Parodontophora marina, Parasphaerolaimus paradoxus, Quadricoma sp.1, Campylaimus sp.1, Halalaimus gracilis, Paramesacanthion sp.1, Paramonohystera sp.1, and Metalinhomoeus longiseta. CLUSTER and SIMPROF analyses revealed three main types of nematode community (or station groups) in the sampling area, including I: coastal community, II: transitory community between coastal and YSCWM (Yellow Sea Cold Water Mass), and III: YSCWM community. Each community was indicated by a number of dominant nematode species. Bio-Env correlation analysis between the nematode community and environmental variables showed that water depth, sediment water content, organic matter, chlorophyll a (Chl-a) and phaeophorbide a (Pha-a) were the most important factors to determine the community structure.     

沉积物镁铝含量比及其古气候意义

沉积物的镁铝含量比——m 值(m=100×MgO/Al_2O_3)与沉积水介质的盐度、pH 水温关系密切。当水温处在冰点以下时,沉积物的m 值随水温降低而增大。当水温处在冰点以上时,水介质的盐度、pH 和水温的增加,都有利于m 值增大。由于气候条件能直接或间接地影响沉积水介质的特征,因此,沉积物的m 值对古气候的变化具有一定的判别功能。通过对中国元古宙以来沉积物m 值的分析,发现古气候的热冷变化有1200Ma 的周期,其中还有次一级的热冷气候波动。第四纪的气候是处在热气候期后期的一个冷的气候波动阶段。     

Carbonate and organic carbon sedimentation on the continental margin off Southeastern Taiwan

Sediment and porewater data of two sediment cores from offshore southeastern Taiwan show important effects of the complex sea floor topography upon carbonate and organic carbon deposition. The variations in carbonate and organic carbon contents are attributed to the effects of carbonate compensation depths, glacial-interglacial history, and condition of anoxia. The study is of significance for environmental reconstruction and petroleum source bed evaluation of ancient analogues.     

Holocene strata along the coastal area of eastern Guangdong

The data of about 1700 drill holes are correlated, of which 47 drill sections are discussed comprehensively for chronology and sedimentology, and the characteristics and changes of sporo-pollen are analysed. The authors consider that the Holocene strata along the coast of eastern Guangdong can be divided into five formations. The Holocene began 12 000 years ago; the fluvial facies gravel, the striped weathered clay and the "old red sand" serves as the boundary between the Holocene and the Pleistocene.
