一、前言 吕四洋位于黄海南端,是我国的主要渔场之一,调查和研究本海区附着生物的附着季节、群落组成和数量变化,不仅在海洋附着生物生态学研究上有重要意义,而且也是防除必需掌握的生物学资料。 我们在调查研究中国沿海主要港湾的附着生物中,把吕四洋列为调查点,并于1977年9月—1978年8月在吕四水文平台进行挂板试验。同时还对吕四水文平台水泥桩上的附着生物的垂直分布,和两个灯浮上的附着生物进行定性、定量的调查。 试验的材料和方法基本上是按照海洋调查规范进行的,只挂底层试验板,分月板、季板和年板。本试验承国家海洋局吕四海洋站的大力协助。
I. Introduction Lv Soyang is located at the southern tip of the Yellow Sea and is one of the major fisheries in China. Investigation and study on the attachment season, community composition and population change of attached organisms in this area not only make great sense in the study of marine bio-ecological attachment, but also are necessary for controlling Master biological information. In our investigation of the attached organisms in the main harbor along the coast of China, Lu Sanyo was included as the investigation point. From September 1977 to August 1978, the peg board experiment was conducted on the Lv Si hydrological platform. At the same time, the vertical distribution of attached organisms on the cement piles of Lv4 hydrological platform and the attached organisms on the two lights float were also investigated qualitatively and quantitatively. The test materials and methods are basically in accordance with the ocean survey norms, only the bottom of the test plate, sub-lunar, seasonal and annual board. This test is supported by the State Oceanic Administration Lvsi Ocean Station.
