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。     

60Co－γ辐照对坛紫菜原生质体诱变的研究

利用^60Co-γ射线对坛紫菜（Porphyra haitanensis）原生质体进行辐照诱变，发现原生质体对^60Co-γ射线有极强的耐受性。前期的培养结果表明，原生质体是一种理想的诱变材料。诱变结果表明，^60Co-γ射线对坛紫菜可诱变剂量范围很大，从200-1300 Gy均有突变株生成。诱变后细胞的存活率不宜作为坛紫菜诱变最佳剂量的指标。

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.     

The algorithms of chlorophyll-a concentration for CMODIS

The algorithms of extracting chlorophyll-a(Chl-a) concentration have been established for Chinese moderate resolution imaging spectrometer(CMODIS) mounted on Shenzhou-3 spaceship launched on 25 March 2002.The CMODIS is an ocean color sensor with 30 visible channels and 4 infrared channels,much different from other ocean color satellites and needs new algorithms to process data.Three models of Chl-a concentration were established based on Chl-a data retrieved from sea-viewing wide field-of-view sensor(SeaWiFS),with the average relative errors of 26.6%,24%.0% and 33.5%,respectively.This practical and economic approach can be used for developing the algorithms of Chinese ocean color and temperature sensor(COCTS) on the satellite Haiyang-1 to derive the Chl-a concentration concentration distribution.The applicability of the algorithms was analyzed using some in situ measurements.Suspended sediment is the main factor influencing the accuracy of the spectral ratio algorithms of Chl-a concentration.The algorithms are suitable to using in the regions where suspended sediment concentrations(SSC) are less than 5 g/m3 under the condition of relative error of Chl-a concentration retrieval within 35%.High concentration of suspended sediment leads to the overestimate remote sensing retrieval of concentration of Chl-a,while low-middle SSCs lead to the low Chl-a concentration values using the spectral ratio algorithms.Since the accuracy of Chl-a concentration by the spectral ratio algorithms is limited to waters of Case 2,it is necessary to develop semi-analytical models to improve the performance of satellite ocean color remote sensing in turbid coastal waters.     

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。
