【摘要】 舟山潮间带生物种类数量的平面分布与盐度和海岸开敞性有关,垂直分布与潮汐有关;群落数量的水平分布与底质和海岸开敞性有关,垂直分布与潮汐有关。舟山潮间带生物有明显的分带现象,隐蔽的岩岸区分为:滨螺带和藤壶-牡蛎带两个带;开敞性岩岸区分为:滨螺带,藤壶-(虫戚)-藻类带及藻类带3个带。沙滩区分为:沙蟹带和浅蛤-斧蛤带两个带;泥沙滩区分为:盐碱植物-滨螺带和招潮蟹-大眼蟹带;泥滩区分为:蟹守螺-囊螺带和蟹守螺-织纹螺带。更多还原

【Abstract】 The Level distributions of species quantities in Zhousan shore are related to the salinity and the expose of shore. The vetical distributions are in relation to the tidal zone. The level quantities distributions of communities are in connection with the substrat and the expose of shore The vertical distributions are connected with the tidal zone. The distributions of biotic zones are obviously classified. As below shows: (1) Shelter reeky shores are divided into two zones: The Littorina zone, Balanus and Ostrea zone. (2) The expose rocky shores have three zones: The Littorina zone, Tetradita, Ce//ana-algae zone and algae zone. (3) Sand beaches are seperated into two zones: The Ocypoda zone and Gomphina-Donax zone. (4) There are two zones in the belt of sand-mud beaches: The halophyte-Littorina zone and Uca-Macropthalmus zone. (5) Mud beaches also have two zones: The Cerithidea-Rutusa zone and Cerithidea-Nassarius zone.更多还原
