柴达木盆地昆特依盐湖的地球化学演化与古气候变化

１９９０年用铀系年代学及古地磁对昆特依盐湖沉积物进行年代测定，探讨该湖区地球化学演化与古气候变化关系。结果表明，该区最老的盐层形成于早更新世晚期（大于７３０ｋａ），大量的盐类沉积则始于３００ｋａ左右；盐湖沉积物中元素含量变化主要受古盐度、矿物、类质同象和吸附控制；沉积物水溶Ｆ／Ｃｌ比值与古盐度成反比关系；该湖２０００ｋａ以来的古环境演变：盐层形成于干冷、偏酸性的氧化环境，泥岩层形成于湿暖、偏碱性的     

中国近海鱼类生活史型与生态学参数地理变异

根据1985－1986年东海北部近海调查材料及其它有关文献，对43种鱼计74个种群或群体的生活史选择型及其生态参数进行了比较研究。结果表明，分布于我国近海的主要鱼类大多偏于r选择型。对r－K选择鱼种的资源特征及其对捕捞的反应作了阐述。各鱼种的种群生态学参数在种间和空间分布均表现出地理变异。     

中国沿海星虫动物门名录

取1980～1989年间在我国沿海进行星虫动物区系调查的标本和有关资料做了整理、鉴定,共39种,分隶于2纲,4目,6科,12属。其中1种在我国为首次记录。     

东海黑潮区海水中磷酸盐的分布特征及成因探讨

本文报道了1987年夏、冬两个航次在26°50′～32°30′N,124°30′～131°30′E海区中可溶性无机磷酸盐的调查结果,阐明了磷的分布特征和形成机制。结果表明陆架区表层测值较高,大洋区为低值区,底层则相反。大洋水常年分层,中层水有爬坡涌升现象,其浓度与Aou呈正相关,与pH和S呈负相关。夏、冬两季底层磷与Aou呈正相关,其浓度变化主要依赖于生物过程。     

钛型吸附剂的表面特性

用自装的BET容量法装置测定了几种粒状钛型吸附剂的比表面及其孔径分布。测定是在常温减压下进行的。结果表明:钛型吸附剂在加铀海水中的吸铀量与样品的比表面及孔径分布有一定的内在联系。这种表面性质的研究对吸附剂的筛选有重要的指导意义。     

The Distribution of Amphipoda in a Brackish-Water Lagoon in Greece

Abstract. The distribution of the benthic Amphipoda was studied in the brackish-water lagoon Mazoma of Amvrakikos Bay, Ionian Sea, Greece. Eleven amphipod species typical of the sublittoral zone, some with preference for enclosed bays and lagoons, were identified. Gammarus crinicornis, Microdeutopus bifidus, C. rotundirostris , and Erichthonius difformis are mentioned for the first time for Greek waters. The distribution of amphipods in the lagoon is governed by the vegetation and is probably modified by interspecific relations.     

盐田中嗜盐菌的初步研究

在连云港台南盐场盐田中取卤水和底泥样品，以盐(NaCl)为限制性生长因子，主要采用12％NaCl平板，对样品中的嗜盐菌进行初步鉴定和培养计数研究。结果表明，盐田中的嗜盐菌类群在菌落、个体特征以及数量分布上有所不同，并且底泥中的菌量比卤水中高1～2个数量级。     

中国鱼类名录Ⅺ--隆头鱼亚目、尤鰧鱼亚目、绵鳚亚目、玉筋鱼亚目

隆头鱼亚目5科63属316种，鰧鱼亚目8科19属53种，绵鳚亚日3科7属8种，玉筋鱼亚目1科3属3种。     

Depth distribution of radiolarians from the Chukchi and Beaufort Seas, western Arctic

The depth distributions of the radiolarian fauna in the Chukchi and Beaufort Seas, marginal seas of the western Arctic Ocean, were examined quantitatively in depth-stratified plankton tows from 4 or 5 intervals above 500 m and in surface sediments from various depths between 163 and 2907 m. The radiolarian assemblage from the water column in September 2000 was dominated by Amphimelissa setosa and followed by the Actinomma boreale/leptoderma group, Pseudodictyophimus gracilipes and Spongotrochus glacialis. These species are related to the Arctic Surface Water shallower than 150 m. This assemblage is similar to that in the Greenland Sea relating to the ice edge, but did not contain typical Pacific radiolarians in spite of the flow of water of Pacific origin in this region. The living depth of Ceratocyrtis historicosa was restricted to the relatively warm water between 300 and 500 m corresponding to the upper Arctic Intermediate Water (AIW) originating from the Atlantic Ocean. Radiolarian assemblages in the surface sediments are similar to those in the plankton tows, except for common Cycladophora davisiana in sediment samples below 500 m. C. davisiana is probably a deep-water species adapted to the lower AIW or the Canadian Basin Deep Water ventilated from the shelves.
