摘要:
海洋附着生物群落的种类组成、附着季节以及数量变动受到各种环境因子的约制,在众多的因子中,往往有少数几个因子起主导作用,成为矛盾的主要方面。作者在以往有关研究中,曾经侧重讨论了离岸远近[1,2]以及盐度梯度[3]和附着生物群落分布的关系。本文提供了东山湾附着生物群落的基本资料,并着重对比在同一港湾中,水流畅通程度和附着生物分布的关系。
Abstract:
Wooden panels were exposed under the rafts at 6 sites of Dongshan bay,Fukien province (Fig.1) for monthly,quarterly,and yearly intervals,1961-1965.The major species are listed in Table 2,the percent coverage of surface and the wet weights per unit time are given in Tahles 3,4 and the seasons of attachment are illustrated in Fig.2.There existed a very great difference in both composition and biomass between the fouling community of Dapingyu (in the mouth of bay with more rapid current and stronger wave action prevailing at this time of the year) and that of the other 5 sites(the various sheltered coastal waters).The result showed that the current was the most important factor that influenced the attachment and growth of fouling organisms.In other words the rapid current favours the attachment and growth of fouling organisms.
