摘    要:2000年在象山港3个养殖区(海带、牡蛎、鱼类)和非养殖区水域进行了四季调查,对养殖区和非养殖区大型底栖生物的生态学进行比较研究。调查鉴定出71种大型底栖生物,其中养殖区45种、非养殖区61种,两区共有种为35种。牡蛎养殖区外侧、鱼类网箱养殖区周围平均生物量和密度分别高达433.53g·m-2和155ind·m-2、91.92g·m-2和114.96ind·m-2;海带养殖区仅为1.55g·m-2和27.5ind·m-2,也明显低于非养殖区5.24g·m-2和53.04ind·m-2;鱼类网箱养殖区中心未见生物分布。本文同时对底栖生物与养殖生物、沉积物及水文环境因子的相关性作了研究探讨。

关 键 词:底栖生物  生态学  养殖区  非养殖区  象山港

Abstract:Seasonal investigations were carried out for 3 cultured areas ( of algae, oyster and fish ) and noncultured area in Xiangshan Bay. 71 species from study areas were identif ied. 45 species of them were collected in cultured areas, 61 species in non-cultured area, 35 species from both cultured and non-cultured areas. The biomass and density in oyster and f ish cultured areas were 433. 53g ..m- 2 and 155ind..m- 2, 91. 92g..m- 2 and 115ind..m- 2 respect ively. It was higher than that in algae cultured area and non-cultured areas. The biomass and density in algae cultured area were 1. 55g..m- 2 and 27. 5ind..m- 2, which was lower than that in non-cultured area ( 5. 24g..m- 2 and 53. 04 ind..m- 2) . No macro-benthic species was found in the center of f ish cultured area. The relativity of the benthos with sediment, reared biology and hydrographic factors is discussed.
Keywords:benthos  ecology  cultured areas  non-cultured areas  Xiangshan Bay
