南极长城湾浅海底栖生物数量的研究

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

本文据 1 987年 1 2月 - 1 988年 3月对南极长城湾底栖生物的三航次 1 9个定量采泥站和4个拖网站的调查资料 ,研究了该湾底栖生物数量的组成、分布特点和变化。指出该湾底栖生物资源量特别大 ,有 2个大范围的高数量区和 2 - 3个小范围的低数量区。沉积物不稳定是造成低数量区的原因。暖季是各种底栖生物生殖期 ,数量月变动明显。

Based on the investigation material acquired during the three cruises of the 4th Chinese Antarctic Research Expedition at 19 quantitative dredging stations and 4th 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, 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.
