厦门西港底栖生物的生态

本文根据1980年11月和1981年2,5,8月在厦门西港调查的底栖生物资料,研究了本区底栖生物的生态特点。结果表明,本区底栖生物333种,主要由多毛类、甲壳动物和软体动物组成;其平均生物量46.53g/m~2;平均栖息密度699个/m~2,这两者分布很不均匀,季节变化明显;环境质量和水动力是影响本区底栖生物分布的主要因子。     

AN ECOLOGICAL STUDY OF BENTHIC ORGANISMS IN THE NEARSHORE WATERS TO THE WEST OF TAIWAN STRAIT

In seven cruises on benthic organisms in the nearshore waters(>50 m) to the west of the Taiwan Strait(23°20''-25°54''N,117°11''-119°58''E) in 1961-1964,altogether 189 stations of quantitative grabbing and 33 stations of qualitative trawling were made.
Altogether 392 species of benthic organisms have been identified.The composition was dominated by nearshore shallow water species,with tropical and subtropical species absolutely dominant.The total average of biomass was 38.0 g/m² and average density,116.0 ind./m².The communities of benthic organisms in the area can be classified into five communities namely,(1) Amphiura sp.-Acaudina molpadioides Community;(2) Protankyra asymmetrica-Arnphioplus pracstans-Murex trapa Community;(3) Modiolus meicalfei-Phyllophorus liuwutiensis-Armandia letocirris-Nephtys sinensis Community;(4) Branchiostoma belcheri-Solenr oseomaculatus-Marphysa sinensis- Onuphis eremita Community;(5) Iconomtra japonica-Barbatia decussata Community.     

A Preliminary Study of Quantitative Distribution of Benthic Animals in the East China Sea Continental Shelf and Its Adiacent Waters

In October and November of 1977 and September and October of 1978,a quantitative survey of benthic animals was conducted in the East China Sea Continental Shelf and its adjacent waters(26°00'-34°00'N,124°00'-129°00'E,water depth 39-1550m),where 307 stations were dredged and 1200 samples collected.     

台湾海峡西部海域软质海底多毛类的生态

本文根据１９８４－１９８５年４航次底栖生物调查资料，首次全面地研究了台湾海峡西部海域多毛类的种类组成，数量分布及其与环境因子的关系。结果表明，该海域多毛类４０４种，习见种１９１种，区系属亚热带性质；平均生物量４．３３ｇ／ｍ＾２，平均栖息密度６８个／ｍ＾２；有沿岸性和外洋性两种明显不同的生态类型，前者位于沿岸水系常年控制海域，种类多，数量较大，后者位于南部粗粒沉积物分布区，种类较少；多毛类高数量区与     

COMMUNITY ANALYSIS OF SHALLOW SEA BENTHOS IN GREAT WALL BAY, ANTARCTICA

The data used in this paper were acquired at 19 quantitative dredging stations and 4 trawling stations during the three crusies of the 4th Chinese Antarctic Research Expedition for investigating the shallow sea benthos in Great Wall Bay, in the period from December 1987 to March 1988. Based on environmental characteristics, diversity of species composition and the eveness of interspecific distribution of individuals, cluster methods were used to divide the investigated area into three benthic community distribution areas. The structures of the various communities were further divided into 3 structure types, namely, high diversity, intermediate diversity and low diversity types. From the study of the relationship between community structure and environmental factors it was pointed out that there was an extremely close relationship between benthic communities structure and the stability of the bottom types and sediments, whereas in sea areas where the depth gradient is not large, there is no obvious relat     

A STUDY ON THE QUANTITY OF SHALLOW SEA BENTHOS IN GREAT WALL BAY, ANTARCTICA

Based on the investigation material acquired during the three cruises of the 4 Chinese Antarctic Research Expedition at 19 quantitative dredging stations and 4 trawling stations from the period December 1987 to March 1988, this paper studies the quantity of the benthos in Great Wall Bay,the distributive characteristics and variations, and points out that the stock number of the benthos in the bay is extremely large and that there are two large ranged high mass area and 2 -3 low small-ranged mass area. The instability of the sediments is the cause for the low mass areas. The warm season is the vigorous reproductive period of the various kinds of the benthos and the monthly variation of the quantity is remarkable.     

南极长城湾浅海底栖生物群落分析

本文采用 1 987年 1 2月 - 1 988年 3月南极长城湾浅海区底栖生物的三航次 1 9个定量采泥站和 4个拖网站的调查资料。根据环境特征、种类组成的多样性和种间个体分配的均匀度 ,采用了聚类方法将调查区分为三个底栖生物群落分布区。并对各群落的结构作进一步分析 ,分为高多样性、中多样性和低多样性三种结构类型。并研究了群落结构与环境因素的关系 ,指出底栖生物的群落结构与底质类型和沉积物稳定性的关系最为密切 ;在深度梯度度不大的海区 ,底栖生物群落结构与深度梯度没有明显关系。     

台湾海峡西部海域底栖生物生态研究——Ⅰ.厦门港底栖动物群落分析

厦门港他于台湾海峡西部金门湾内,包括九龙江口、厦门外港、厦门西港和浔江海域,系一个亚热带河口港湾,本港不同程度地受到南海水系和浙闽南下沿岸流的影响,生物区系比较复杂,郑重、金德祥、黄宗国等人已先后研究了该港的浮游动物、浮游植物、附着生物和潮间带生物[2-4],但迄今为止,对厦门港浅海带和潮下带底栖动物生态学的研究,尚未见报道.国家海洋局第三海洋研究所于1980-1981年对该港进行了周年逐月的综合调查,本文根据其中四个季度月(2、5、8、11)底栖动物资料整理而成.     

Quantitative Distribution of Deep-water Benthos in Western Central Pacific

Altogether 10 surfaces and 8 cores were sampled quantitatively from the Western Central Pacific(4°00′S—5°00′N, 160°00′—165°00′E and 2°00′—10°00′S, 170°00′—173°20′E) in 1978 and 1979. The results of preliminary analysis show that the faunal composition was quite simlpe, only eight species of macrobenthic invertebrates, four species of Polychaete, two
