摘要
本文报导了１９９７．７－１９９８．４期间北麂列岛岩相潮间带底栖生物群落的组成特征。研究结果表明：总平均生物量和栖息密度分别为５０９１．８０９·ｍ－２和４２６９个·ｍ－２；生物量和栖息密度的水平分布为关帝山＞大筲箕屿＞海利＞壳菜岙，垂直分布为中潮区＞低潮区＞高潮区，生物量和栖息密度的季节变化分别为冬季＞春季＞秋季＞夏季和冬季＞秋季＞春季＞夏季。数量的水平分布主要受海岸开敞度及浪击度的影响、垂直分布主要受潮区及浪击度的影响、季节变化主要受温度和动植物繁殖的影响。
This paper is a report of the quantity distribution of the benthic community in the rocky intertidal zone of Bet n islands from July 1997 to April 1998. The results show that the average biomass and density are 5091 .80 g .m-2 and 4269md .m-2 respectively. The biomass and density of the horizontal distribution is in the order of Guandishan>Daxiaoqiyu>HaiIi>Kecaiao, and the vertical distribution are in the order of the mid-tide area>the low-tide area>the high-tide area The seasonal changes of the biomass are in the order of Winter> Spring>Autumn>Summer and the density are in the order of Winter>Autumn>Spring>Summer. The horizontal distrbutions of quantities are related to the seashore open degree and the lapping degree of waves, the vertical distributions are related to the tidal zone and the lapping degree of waves, but the seasonal changes are in connection with the temperature and the reproduction of animals and plains.
