山东省大中型水库浮游生物研究──Ⅰ．浮游动物生态

报道１９８９～１９９０年山东省３０多个大中型代表水库浮游动物的种类组成，种类频级、优势类群。主要种和生物量；统计分析掠食性与植食性浮游动物生物量，浮游动物与浮游植物生物量及浮游动物与代表水库营养状态指标的总磷，透明度和深度的关系。提出浮游动物个体越小，其生物量与水库营养水平关系越密切。     

安徽宣城地区中晚更新世风成堆积与环境变迁

通过对宣城向阳中晚更新世沉积剖面的综合研究,认为该剖面与中国北方同时代的黄土—古土壤剖面相比较,虽然长江下游以南地区中晚更新世多个冰期中风成堆积的单层厚度与累积厚度,亦即风成物质的沉积通量与沉积速率均比北方黄土区要小,但它们所反映的气候与环境的变化具有明显的可比性。     

太阳黑子、厄尔尼诺及西北太平洋热带气旋的活动

本文用１９００～１９９４年的资料，以统计分析的方法，对太阳黑子，厄尔尼诺及西北太平洋热带气旋活动的相互关系，进行了初步探讨，归纳出几点有参考价值的结论

一个南海热带气旋发展的环流特征分析

本文用ECMWF2.5×2.5网格点资料通过一个例子,对有利于南海热带气旋发展的环流场作了详细的分析,发现几点事实:(1)扰动在风的垂直切变较大的环境中仍可发展。(2)扰动位于中、低空西南急流左侧,高空南支东风急流右侧时,有利发展。(3)中,低空西南急流形成了扰动环流的强风潮,强风潮从扰动南侧入角,并包围扰动的东半圆。(4)扰动中、低层的入流和高层的外流呈现严重的不对称性。(5)当扰动发展到一定强度时,对南海热带季风环流圈的加强起到正反馈作用。     

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。     

西沙群岛附近海域羽纹硅藻分类研究 Ⅰ

继“西沙、中沙群岛附近海域浮游硅藻类分类的研究”之后,作者又对西沙群岛所属岛、礁附近海域的羽纹硅藻进行了初步整理,共鉴定出羽纹硅藻11属27种及其变种(其中8种是我国首次记录)。本文对首次记录的种类进行了比较详细的说明和绘图。某些在我国其他海域已有报道的种类,如光辉针杆藻、串珠梯楔形藻、海生斑条藻、琴状舟形藻、流苏胸隔藻、双标胸隔藻、钝端双眉藻、细纹斜盘藻等,以往的描述较简单,并且与西沙群岛标本的形态也不完全雷同,为了便于应用和比较,本文根据西沙群岛的标本,又进行了较详细的描述或补充说明。对有图而无说明,或仅有名录的种类的国内资料,在地理分布内注明。为了保持西沙群岛所属海城硅藻分类研究的连续性,本文仍采用 Hendey 提出的分类系统排列。 为便于读者査找,每一种名下列出其同物异名。 标本多用小型浮游生物网采得,有些则取自珊瑚表面。插图均用描图仪描绘。     

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。     

Variation of reactivity of particulate and sedimentary organic matter along the Zhujiang River Estuary

To investigate organic matter source and reactivity in the Zhujiang River (Pearl River)Estuary and its adjacent areas, particulate organic carbon (POC), particulate hydrolysable amino acids (PHAA), and Chl a during two cruises in July 1999 and July 2000 were measured. The highest POC and PHAA concentration was observed in the waters with maximum Chl a. The spectra distribution,relative content (dry weight in milligram per gram), PHAA-C% POC and other indicators such as the ratios of amino acids vs. amino sugars (AA/AS) and glucosamine vs. galactosamine (Glum/Gal) suggested that particulate amino acids in the water column and sediments in the Zhujiang River Estuary were mainly derived from biogenic processes rather than transported from terrestrial erosion. In inner estuary where high turbidity was often observable, organic matter was mainly contributed by re-suspension of bottom sediments with revealed zooplankton, microbial reworked characteristics, which suggest that these organic matters were relatively “old“. In the estuarine brackish region, organic matter in water column is mainly contributed by relatively fresh, easily degradable phytoplankton derived organic matter.During physical - biological processes within the eastuary, organic matter derived from phytoplankton was subjected to alteration by zooplankton grazing and bacterial reworking.
