【摘要】 本文报导榆林港附着生物的的种类组成及其季节变化,并从种类、附着量及附着季节等方面与厦门港的附着生物作比较。 榆林港最主要的附着生物是:滸苔、管滸苔、水云、褐茸藻及笼果藻等藻类;盤管虫、螺旋虫、(?)牡蠣、(?)合草苔虫及悉尼海(?)等动物,藻类月附着量9.5克/米~2,季附着量3.1克/米~2;动物月附着量5.8克/米~2,季附着量187.1克/米~2。种类多、附着期长、附着量少是榆林港附着生物的主要特点。 榆林港与厦门港附着生物的差异,反映了热带性和亚热带性港湾附着生物的特点;也表明了深海外港与河口内港(盐度及透明度不同)在生态上的意义。更多还原

【Abstract】 The present paper emhodies the results of investigations on the composition of fouling organisms of Yu-lin harbour and its seasonal variation. A comparison is made of the fouling organisms of this harbour with those of Amoy harbour in the respects of their composition, biomass and seasonal fluctuation.The dormanant fouling plants of Yu-lin harbour are: Enteromorpha clathrata, E. tubulosa, Ectocapus confervoides, Giffordia spp. and Sp(?)ridia filamentosa, and the dormanant fouling animals are: Hydroldes sp., Spirorbis sp., Ostrea cremilifera, Bugularia neritina and Ascida sydneinesis. The biomass of plants is 9.5g/M~2 per month and 3.1g/M~2 per season. The biomass of animals is 5.8g/M~2 per month and 187.1g/M~2 per season. The chief ecological chara cteristics of fouling organisms of Yu-lin harbour are: large number of species, long period of attachment and the small biomass.There exists a great difference in both composition and biomass between the fouling organisms of Yu-lin harbour and those of Amoy harbour which reflects the subtropical and tropi cal nature of these two harbours. The difference is also due to the fact that. Yu-lin. harbour is situated nearby the deep sea with high salinity and transparency, whilst Amoy harbour is situated nearby the mouth of Giulong estuary with low salinity and transparency.更多还原
