根据浙江省海岛资源调查资料 ,对台州列岛海域的贝类作了统计分析。结果表明 ,该区共发现贝类 46种 ,隶属 2纲 8目 2 4科。种类组成以广温广布种为主 ,其次为亚热带种 ,暖温带种和热带种所占的比例较少。全区平均生物量为 1 8.0 6g/m2 ,平均栖息密度为 2 67.1 6个 /m2 。数量季节变化显著。这些特征与海流、沉积物等环境因子密切相关。
According to the survey data of island resources in Zhejiang Province, the shellfish in the Taizhou archipelago area were analyzed statistically. The results showed that 46 species of shellfish were found in the area, belonging to 2 orders, 8 orders and 24 families. The species composition is mainly broad-width broad-leaved species, followed by subtropical species, while warm temperate species and tropical species account for a relatively small proportion. The average biomass of the whole area was 1 8.06g / m2, with an average habitat density of 2 67.1 6 / m2. The number of seasonal changes significantly. These features are closely related to environmental factors such as currents and sediments.
